控制模板
我对 WPF 很陌生，有一个基本问题： 假设以下是我的 xaml 文件中的 xaml 声明
<ContentControl x:Name="interactionActivityContent" Loaded="interactionActivityContent_Loaded">
<shapes:BaseShape.DragThumbTemplate >
<ControlTemplate x:Name="interactionActivityTemplate">
<Grid AllowDrop="True" x:Name="GridTest" >
<Rectangle Name="Interaction" Fill="Yellow" Stroke="Green" StrokeThickness="2" IsHitTestVisible="True" AllowDrop="True"></Rectangle>
<local:DesignerCanvas x:Name="ActivitiesCanvasArea" Margin="1,1,1,1" IsHitTestVisible="True" AllowDrop="True" Background="Blue"></local:DesignerCanvas>
</Grid>
</ControlTemplate>
</shapes:BaseShape.DragThumbTemplate>
*shapes:BaseShape.DragThumbTemplate 来自一些不同的类。 *DesignerCanvas 是我自己的自定义画布，我想在运行时为其设置值。 如何从代码隐藏文件中访问 C# 代码中的 ActivityCanvasArea？ 我是否需要更改 xaml 的声明方式？我需要将 DragThumbTemplate 应用到我的网格，以便我可以在主屏幕上的网格中移动。
I am quite new to WPF and have a basic question :
Assume the following is xaml declaration in my xaml file
<ContentControl x:Name="interactionActivityContent" Loaded="interactionActivityContent_Loaded">
<shapes:BaseShape.DragThumbTemplate >
<ControlTemplate x:Name="interactionActivityTemplate">
<Grid AllowDrop="True" x:Name="GridTest" >
<Rectangle Name="Interaction" Fill="Yellow" Stroke="Green" StrokeThickness="2" IsHitTestVisible="True" AllowDrop="True"></Rectangle>
<local:DesignerCanvas x:Name="ActivitiesCanvasArea" Margin="1,1,1,1" IsHitTestVisible="True" AllowDrop="True" Background="Blue"></local:DesignerCanvas>
</Grid>
</ControlTemplate>
</shapes:BaseShape.DragThumbTemplate>
*shapes:BaseShape.DragThumbTemplate is coming from some different class.
*DesignerCanvas is my own custom canvas for which I want to set value at run time.
How can I access ActivitiesCanvasArea in my C# code from the code behind file?
Do I need to change the way xaml is declared. I need to apply DragThumbTemplate to my grid so that I can move around grid on main screen.

如果您需要在 myButton1 的 ControlTemplate 中查找命名元素（例如 Grid），您可以使用 Template.FindName，如下所示：
//Finding the grid generated by the ControlTemplate of the Button
网格 gridInTemplate = (Grid)myButton1.Template.FindName("grid", myButton1);

If you need to find a named element in the ControlTemplate of myButton1, like the Grid, you can use Template.FindName like so:
// Finding the grid generated by the ControlTemplate of the Button
Grid gridInTemplate = (Grid)myButton1.Template.FindName("grid", myButton1);
