1、 如何解决单击记录整行选中的问题

View->OptionsBehavior->EditorShowMode 设置为:Click

 

2、 如何新增一条记录

(1)、gridView.AddNewRow()

(2)、实现 gridView_InitNewRow 事件

 

3、如何解决 GridControl 记录能获取而没有显示出来的问题

gridView.populateColumns();

 

4、如何让行只能选择而不能编辑(或编辑某一单元格)

(1)、View->OptionsBehavior->EditorShowMode 设置为:Click

(2)、View->OptionsBehavior->Editable 设置为:false

 

5、如何禁用 GridControl 中单击列弹出右键菜单

设置 Run Design->OptionsMenu->EnableColumnMenu 设置为:false

 

6、如何隐藏 GridControl 的 GroupPanel 表头

设置 Run Design->OptionsView->ShowGroupPanel 设置为:false

 

7、如何禁用 GridControl 中列头的过滤器 过滤器如下图所示:     

设置 Run Design->OptionsCustomization->AllowFilter 设置为:false

 

 

8、如何在查询得到 0 条记录时显示自定义的字符提示/显示 如图所示:

方法如下:

//When no Records Are Being Displayed

 

private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)

 

{

 

 //方法一(此方法为GridView设置了数据源绑定时,可用)

 

 ColumnView columnView = sender as ColumnView;

 

BindingSource bindingSource = this.gridView1.DataSource as BindingSource;

 

if(bindingSource.Count == 0)

 

{

 

string str = "没有查询到你所想要的数据!";

 

Font f = new Font("宋体", 10, FontStyle.Bold);

 

Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);

 

e.Graphics.DrawString(str, f, Brushes.Black, r); }

 

//方法二(此方法为GridView没有设置数据源绑定时,使用,一般使用此种方 法)

 

if (this._flag)

 

 { if (this.gridView1.RowCount == 0)

 

 { string str = "没有查询到你所想要的数据!"; Font f = new Font("宋体", 10, FontStyle.Bold);

 

Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);

 

e.Graphics.DrawString(str, f, Brushes.Black, r); } } }

 

 

 

9、如何显示水平滚动条?或

 

设置 this.gridView.OptionsView.ColumnAutoWidth = false;

 

 

 

.....列表宽度自适应内容

 

gridview1.BestFitColumns();

 

 

 

10、如何定位到第一条数据/记录?

 

设置 this.gridView.MoveFirst()

 

 

 

11、如何定位到下一条数据/记录?
设置 this.gridView.MoveNext()

 

 

 

12、如何定位到最后一条数据/记录?

 

设置 this.gridView.MoveLast()

 

 

 

13、设置成一次选择一行,并且不能被编辑

 

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

 

 this.gridView1.OptionsBehavior.Editable = false;

 

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

 

 

 

 14、如何显示行号?
  private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
            if (e.Info.IsRowIndicator)
            {
                if (e.RowHandle >= 0)
                {
                    e.Info.DisplayText = (e.RowHandle + 1).ToString();
                }
                else if (e.RowHandle < 0 && e.RowHandle > -1000)
                {
                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                    e.Info.DisplayText = "G" + e.RowHandle.ToString();
                }
            }
        }

 

 

 

15、如何让各列头禁止移动?

 

设置 gridView1.OptionsCustomization.AllowColumnMoving = false;

 

16、如何让各列头禁止排序?

 

设置 gridView1.OptionsCustomization.AllowSort = false;

 

17、如何禁止各列头改变列宽?

 

设置 gridView1.OptionsCustomization.AllowColumnResizing = false;

 

 

 

18.拖动滚动条时固定某一列

设置Columns,选择要固定的列。设置Fixed属性,可以选择:固定在左边、固定在右边、不固定。

 

 

 

19.获取选定行,指定列单元格的内容

 

      return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();

 

20.分组显示

 

OptionsView>OptionsBehavior>AutoExpandAllGroups = True
选择要分组的列,将GroupIndex属性设置为0

 

21.格式化数据

 

       private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
        {
            if (this.gvList.FocusedColumn.FieldName == "passQty")
            {
                string passQty = e.Value.ToString().Trim();
                int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty;
                if (!JXType.IsIntBigThanZero(passQty))
                {
                    e.Valid = false;
                    e.ErrorText = "合格数量必须为大于等于0小于等于接货数量的整数!";
                }
                else
                {
                    if (int.Parse(passQty) > receiveQty)
                    {
                        e.Valid = false;
                        e.ErrorText = "合格数量必须为大于0小于等于接货数量的整数!";
                    }
                }
            }

 

}

 

 

 

22.合并表头

 

   ///初始化表格

 

using DevExpress.XtraGrid.Columns;
using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.BandedGrid;
using DevExpress.XtraEditors.Repository;
        private void InitGrid()
        {
            // advBandedGridView1是表格上的默认视图,注意这里声明的是:BandedGridView
            BandedGridView view = advBandedGridView1 as BandedGridView;
            view.BeginUpdate(); //开始视图的编辑,防止触发其他事件
            view.BeginDataUpdate(); //开始数据的编辑
            view.Bands.Clear();

 

            view.OptionsView.ShowColumnHeaders = false;                         //因为有Band列了,所以把ColumnHeader隐藏
            //添加列标题
      //添加列标题
            GridBand bandID = view.Bands.AddBand("ID");
            bandID.Visible = false; //隐藏ID列
            GridBand bandName = view.Bands.AddBand("姓名");
            GridBand bandSex = view.Bands.AddBand("性别");
            GridBand bandBirth = view.Bands.AddBand("出生日期");
            GridBand bandScore = view.Bands.AddBand("分数");
            GridBand bandMath = bandScore.Children.AddBand("数学");
            GridBand bandChinese = bandScore.Children.AddBand("语文");
            GridBand bandEnglish = bandScore.Children.AddBand("英语");
            GridBand bandSubTotal = bandScore.Children.AddBand("小计");
            GridBand bandRemark = view.Bands.AddBand("备注");

 

            bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//这是合并表头居中显示
            view.EndDataUpdate();//结束数据的编辑
            view.EndUpdate();   //结束视图的编辑
        }

具体可看 

dev gridcontrol 合并表头

 

23.   //动态添加列
            DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();
            Col1.FieldName = "name";
            Col1.Caption = "名字";
            Col1.Visible = false;
            Col1.VisibleIndex = gvCountry.Columns.Count;
            gvCountry.Columns.Add(Col1);

 

24。设置自动增加的行号

  private void gridview_CustomDrawRowIndicator(object sender,                            DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
    {

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
            if (e.Info.IsRowIndicator)
            {
                if (e.RowHandle >= 0)
                {
                    e.Info.DisplayText = (e.RowHandle + 1).ToString();
                }
                else if (e.RowHandle < 0 && e.RowHandle > -1000)
                {
                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                    e.Info.DisplayText = "G" + e.RowHandle.ToString();
                }
            }

25.特效:gridcontrol中有5种view 型式,普通的是gridview,然后分别为cardview、BandedView、Advanced BandedView、LayoutView;共5种。

  1)、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了
  2)、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角 
  3)、Roll Angle 属性决定着 倾侧角度
  4)、指定数据源,显示数据:
  //显示数据
        private void showData(List<Employee > list)
        {
            DataTable dt = new DataTable("OneEmployee");
            dt.Columns.Add("Caption", System.Type.GetType("System.String"));
            dt.Columns.Add("Department", System.Type.GetType("System.String"));
            dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

            for (int i = 0; i < list.Count; i++)
            {
                DataRow dr = dt.NewRow();
                dr["Caption"] = list[i].Name;
                dr["Department"] = list[i].Department;
                string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;
                dr["PhotoName"] = getImageByte(imagePath);
                dt.Rows.Add(dr);
            }
            gridControl1.DataSource = dt;
        }

        //返回图片的字节流byte[]
        private byte[] getImageByte(string imagePath)
        {
            FileStream files = new FileStream(imagePath, FileMode.Open);
            byte[] imgByte = new byte [files.Length ];
            files.Read(imgByte, 0, imgByte.Length);
            files.Close();
            return imgByte;
        }

 

26.检查数据的有效性

  在gridview的ValidateRow事件中加入检查代码:
  #region 检查数据
  private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)
  {
  GridView view = sender as GridView;
  view.ClearColumnErrors();

  if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)
  {
  e.Valid = false;
  view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");
  }

  }

 

27.设某一列文字和标题局中显示                  
   gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
   gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

 

28.列表过滤条件多选

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

 

29.隔行换色的方法

 this.gridView1.Appearance.OddRow.BackColor = Color.White;  // 设置奇数行颜色 // 默认也是白色 可以省略 
this.gridView1.OptionsView.EnableAppearanceOddRow = true;   // 使能 // 和和上面绑定 同时使用有效 
this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 设置偶数行颜色 
this.gridView1.OptionsView.EnableAppearanceEvenRow = true;   // 使能 // 和和上面绑定 同时使用有效

 

 

1.隐藏最上面的GroupPanel
gridView1.OptionsView.ShowGroupPanel=false;

2.得到当前选定记录某字段的值
sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

3.数据只读
gridView1.OptionsBehavior.Editable=false;

4.不显示MasterDetailView
gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel内容
gridView1.GroupPanelText="柳生飘絮";

6.设置数据源:
gridControl1.DataSource = dt;
绑定每一列的FiledName--属性
对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.

7.读写拷贝权限设置
只读不可拷贝:
ColumnViewOptionsBehavior.Editable = False

只读可拷贝:
ColumnViewOptionsBehavior.Editable = True
OptionsColumn.AllowEdit = True
OptionsColumn.ReadOnly = True

可编辑:
ColumnViewOptionsBehavior.Editable = True
OptionsColumn.AllowEdit = True
OptionsColumn.ReadOnly = False

8.模板列的设置:
到Columns中,在他的属性中找到ColumnEdit.
以LookUpEdit为例:
首先从Designer左边菜单In-Place Editor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空.
  AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为True.
  SearchMode设置为OnlyInPopup.
  然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)
  最后我们还要在代码里面给Re1绑定数据源和显示项.
Re1.DataSource = DALUse.Query("select fid,fname,fsex from dual").Tables[0];
Re1.DisplayMember = "FSEX";
Re1.ValueMember = "FNAME";

 

9.设某一列文字和标题局中显示
gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;


10.去掉某一列上面的自动筛选功能(Filter)
gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;
gridView1.Columns[0].OptionsFilter.AllowFilter = false;
gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false;


11.设置冻结列(左冻结)
gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;


12.得到单元格数据(0行0列)
string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]);
string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);


13.设置单元格数据(将0行0列的单元格赋值123)
gridView1.SetRowCellValue(0, gridView1.Columns[0], "123");


13.手动添加dev的列
DevExpress.XtraGrid.Columns.GridColumn Col1=new DevExpress.XtraGrid.Columns.GridColumn ();
Col1.FieldName="FID";
Col1.Visible=true;
Col1.VisibleIndex=gridView1.Columns.Count;
gridView1.Columns.Add(Col1);


14.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator

private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
if (e.Info.IsRowIndicator && e.RowHandle >= 0)
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}

15.删除: (修改了dgvdel里的datagridviewdel方法)
public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)
{
if (MessageBox.Show("你确定要删除选中的记录吗?", "删除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)
{
int iSelectRowCount = Mydgv.SelectedRowsCount;
if (iSelectRowCount > 0)
{
Mydgv.DeleteSelectedRows();
}
}
}

16. 新增: (对于新增,其本身的AddNewRow方法就可以做到)
private void btn_add_Click(object sender, EventArgs e)
{
gridView1.AddNewRow();
}
具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写:
private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
{
ColumnView View = sender as ColumnView;
View.SetRowCellValue(e.RowHandle, View.Columns[0], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[0])); //复制最后一行的数据到新行

View.SetRowCellValue(e.RowHandle, View.Columns[1], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[1])); //复制最后一行的数据到新行

}


17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以)


18.特效:gridcontrol中有5种view 型式,普通的是gridview,然后分别为cardview、BandedView、Advanced BandedView、LayoutView;共5种。
1)、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了
2)、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角
3)、Roll Angle 属性决定着 倾侧角度
4)、指定数据源,显示数据:
//显示数据
private void showData(List<Employee > list)
{
DataTable dt = new DataTable("OneEmployee");
dt.Columns.Add("Caption", System.Type.GetType("System.String"));
dt.Columns.Add("Department", System.Type.GetType("System.String"));
dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

for (int i = 0; i < list.Count; i++)
{
DataRow dr = dt.NewRow();
dr["Caption"] = list[i].Name;
dr["Department"] = list[i].Department;
string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;
dr["PhotoName"] = getImageByte(imagePath);
dt.Rows.Add(dr);
}
gridControl1.DataSource = dt;
}

//返回图片的字节流byte[]
private byte[] getImageByte(string imagePath)
{
FileStream files = new FileStream(imagePath, FileMode.Open);
byte[] imgByte = new byte [files.Length ];
files.Read(imgByte, 0, imgByte.Length);
files.Close();
return imgByte;
}

19.检查数据的有效性
在gridview的ValidateRow事件中加入检查代码:
#region 检查数据
private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)
{
GridView view = sender as GridView;
view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)
{
e.Valid = false;
view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");
}

}
#endregion
调用gridview.UpdateCurrentRow()方法执行检查


最常用的DevExpress Winform 4个代码片段:

一 、GridControl的删除操作

private void rILinkEditInfoDel_Click(object sender, EventArgs e)
{
if (XtraMessageBox.Show("请确定是否删除当前记录?", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
{
DataRow row = gvInfos.GetDataRow(gvInfos.FocusedRowHandle);
delByCode(row["Code"].ToString());
XtraMessageBox.Show("操作成功!");
}
}

二、绑定非数据表中列

Hashtable ht = new Hashtable();

private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{
GridView View = sender as GridView;
if (e.RowHandle >= 0)
{
object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);
if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns["Value"]) != DBNull.Value)
{
decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));
object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]);
object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]);
if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")
{
decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]));
decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]));
if (gridColumn2 > AverValue || AverValue > gridColumn1)
{
if (!ht.ContainsKey("pic"))
ht.Add("pic", GetImage(1));
e.Value = ht["pic"];
}
}
}
}
}

/// <summary>
/// 由资源文件获取图片
/// </summary>
/// <param name="key"></param>
/// <returns></returns>
byte[] GetImage(int key)
{
Image img = DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif", key.ToString()), typeof(RiverInfos).Assembly);
return DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img, ImageFormat.Gif);
}

/// <summary>
/// 动态根据条件设置行样式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void gridView6_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{
GridView View = sender as GridView;
if (e.RowHandle >= 0)
{
object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);
if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns["Value"]) != DBNull.Value)
{
decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));
object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]);
object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]);
if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")
{
decimal gridColumn2 = Convert.ToDecimal(MinValue);
decimal gridColumn1 = Convert.ToDecimal(MaxVlaue);
if (gridColumn2 > AverValue || AverValue > gridColumn1)
{
e.Appearance.ForeColor = Color.Red;
e.Appearance.BackColor = Color.LightGray;
}
}
}
}
}

三、GridControl 中颜色选择控件

private void gvMapColor_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{
GridView view = sender as GridView;
DataView dv = view.DataSource as DataView;
if (e.IsGetData)
{
string strVal = dv[e.ListSourceRowIndex]["Color"].ToString();
if (strVal != "")
{
//e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal);
e.Value = Common.HexToColor(strVal);
}
}
else
{
//Color colorVal = DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString());
Color colorVal = (Color)e.Value;
dv[e.ListSourceRowIndex]["Color"] = Common.RGB_HEX(colorVal.ToArgb());
}
}

四、关于 GridControl 验证示例

/**//// <summary>
/// 初始化GridView,绑定数据
/// </summary>
/// <param name="parentId"></param>
private void GridViewBindData(string parentId)
{
this.gridView1.Columns.Clear();
this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);
this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

this.gridView1.Columns["id"].VisibleIndex = -1;
this.gridView1.Columns["childCounts"].VisibleIndex = -1;

this.gridView1.Columns["reg_id"].Caption = "区划编号";
this.gridView1.Columns["reg_name"].Caption = "区划名称";
this.gridView1.Columns["parent_id"].Caption = "父区划编号";
this.gridView1.Columns["reg_desc"].Caption = "区划描述";
this.gridView1.Columns["parent_id"].ImageIndex =1;
this.gridView1.Columns["reg_desc"].ImageIndex = 0;

RepositoryItemTextEdit textEditReg_Id = new RepositoryItemTextEdit();
textEditReg_Id.Mask.EditMask =parentId+"\\d{2,3}";
textEditReg_Id.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.Regular;

this.gridView1.Columns["reg_id"].ColumnEdit = textEditReg_Id;

this.gridView1.Columns["reg_desc"].ColumnEdit = new RepositoryItemMemoExEdit();

TreeListNode node = this.treelArea.FocusedNode.ParentNode;
string fid = node==null?"0":node.GetValue("RegID").ToString().Trim();
DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);
RepositoryItemLookUpEdit lookUEParent_Id = new RepositoryItemLookUpEdit();
lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_id", 40, "区划编号"));
lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_name", 40, "区划名称"));
lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;
lookUEParent_Id.ValueMember = "reg_id";
lookUEParent_Id.DisplayMember = "reg_id";
this.gridView1.Columns["parent_id"].ColumnEdit = lookUEParent_Id;
}
/**//// <summary>
/// gridView单元格验证的相关处理程序
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void gridView1_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
{
if (e.Valid == false&this.gridView1.FocusedColumn.FieldName == "reg_id")
{
e.ErrorText = "区划编号不合法!\n应为父区划编号加2~3位数据组成!";
}
if (this.gridView1.FocusedColumn.FieldName == "reg_name")
{
Regex reg=new Regex(@"[\u4e00-\u9fa5]{1,20}");
Match m=reg.Match(e.Value.ToString().Trim());
if (m.Length != e.Value.ToString().Trim().Length)
{
e.Valid = false;
e.ErrorText = "区划名称应为汉字\n长度为1至20";
}
}
}

private void gridView1_InvalidValueException(object sender, InvalidValueExceptionEventArgs e)
{
if (MyDialog.Alert(" 您所填写的内容不符合规则\n 要放弃您刚才对此项所做的更改吗?", "您所编辑的内容不符合规则", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
{
e.ExceptionMode = ExceptionMode.Ignore;
}
}

/**//// <summary>
/// gridView行验证的相关处理程序
/// </summary>
private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)
{
string regid = this.gridView1.GetRowCellValue(e.RowHandle, "reg_id").ToString().Trim();
string regName = this.gridView1.GetRowCellValue(e.RowHandle, "reg_name").ToString().Trim();
if ( regid.Length < 1)
