将RichTextBox绑定到C#中的Slider控件

我有以下要在xaml.cs中执行的XAML代码.

<RichTextBox.LayoutTransform>
    <ScaleTransform ScaleX="{Binding ElementName=mySlider, Path=Value}"
                    ScaleY="{Binding ElementName=mySlider, Path=Value}"/>
</RichTextBox.LayoutTransform>

基本上它将滑块绑定到richtextbox并执行缩放.

以下是我的尝试：

RichTextBox newtext = new RichTextBox();
ScaleTransform mytran = new ScaleTransform();
mytran.ScaleX = mySlider.Value;
mytran.ScaleY = mySlider.Value;
newtext.LayoutTransform = mytran;

解决方法:

后面的代码相当于Xaml

//<RichTextBox.LayoutTransform>
//    <ScaleTransform ScaleX="{Binding ElementName=mySlider, Path=Value}"
//                    ScaleY="{Binding ElementName=mySlider, Path=Value}"/>
//</RichTextBox.LayoutTransform>

ScaleTransform scaleTransform = new ScaleTransform();
Binding scaleXBinding = new Binding("Value");
scaleXBinding.Source = mySlider;
Binding scaleYBinding = new Binding("Value");
scaleYBinding.Source = mySlider;
BindingOperations.SetBinding(scaleTransform,
                             ScaleTransform.ScaleXProperty,
                             scaleXBinding);
BindingOperations.SetBinding(scaleTransform,
                             ScaleTransform.ScaleYProperty,
                             scaleYBinding);

RichTextBox newText = new RichTextBox();
newText.LayoutTransform = scaleTransform;
