GridView’GridView1’触发事件排序未处理

我已经在C#中使用工具箱创建了一个gridview,
它可以显示&对我的sqldatasource中的项目进行排序,但是当我更改sqldatasource时,如在下面的代码中可以看到的那样,它显示错误“未处理的GridView’GridView1’触发事件排序”

SqlDataSource searchResults = new SqlDataSource(WebConfigurationManager.ConnectionStrings["MyDbConn"].ToString(), "SELECT * FROM Books WHERE id=1");
GridView1.DataSourceID = null;
GridView1.DataSource = searchResults;
GridView1.DataBind();

以下是我的gridview&我的Default.aspx中的sqldataconnection代码(由工具箱中的拖放创建)

        <asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
        AllowSorting="True" AutoGenerateColumns="False" 
        DataSourceID="SqlDataSource1" BackColor="White" BorderColor="#DEDFDE" 
        BorderStyle="None" BorderWidth="1px" CellPadding="4" ForeColor="Black" 
        GridLines="Vertical" Width="748px">
        <AlternatingRowStyle BackColor="White" />
        <Columns>
            <asp:BoundField DataField="Id" HeaderText="Id" SortExpression="Id" />
            <asp:BoundField DataField="BookName" HeaderText="BookName" 
                SortExpression="BookName" />
            <asp:BoundField DataField="Status" HeaderText="Status" 
                SortExpression="Status" />
            <asp:BoundField DataField="ReturnDate" HeaderText="ReturnDate" 
                SortExpression="ReturnDate" />
            <asp:CheckBoxField DataField="Reserve" HeaderText="Reserve" 
                SortExpression="Reserve" />
        </Columns>
        <FooterStyle BackColor="#CCCC99" />
        <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" />
        <RowStyle BackColor="#F7F7DE" />
        <SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" />
        <SortedAscendingCellStyle BackColor="#FBFBF2" />
        <SortedAscendingHeaderStyle BackColor="#848384" />
        <SortedDescendingCellStyle BackColor="#EAEAD3" />
        <SortedDescendingHeaderStyle BackColor="#575357" />
    </asp:GridView>

    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ConnectionStrings:MyDbConn %>" 
        SelectCommand="SELECT * FROM [Books]"></asp:SqlDataSource>

解决方法:

更新

您无需动态添加新的数据源,因为您要更改的只是数据源的SelectCommand.做就是了

SqlDataSource1.SelectCommand = "SELECT * FROM Books WHERE id=1";
gv.DataBind();

如果您想通过搜索字词搜索图书,则可以执行以下操作

SqlDataSource1.SelectCommand = "SELECT * FROM Books WHERE id LIKE '%" + searchTxt.Text + "'%";
gv.DataBind();

据我所知,动态添加新的数据源似乎会引起严重的问题.

请试试

SqlDataSource searchResults = new SqlDataSource(WebConfigurationManager.ConnectionStrings["MyDbConn"].ToString(), "SELECT * FROM Books WHERE id=1");
searchResults.ID = "searchResults"; //or something else
this.Controls.Add(searchResults);
GridView1.DataSourceID = searchResults.ID;
GridView1.DataBind();

或更容易

 SqlDataSource searchResults = new SqlDataSource(WebConfigurationManager.ConnectionStrings["MyDbConn"].ToString(), "SELECT * FROM Books WHERE id=1");
this.Controls.Add(searchResults);
GridView1.DataSource = searchResults;
GridView1.DataBind();
