C# 如何在自定义控件模板中访问UI元素？

在此自定义控件的控件模板中

<ControlTemplate TargetType="{x:Type local:CustomLineGraph}">
         <StackPanel Orientation="Vertical">               
              <Canvas x:name"myCanvas"></Canvas>
              <Border Background="#FF0000"
                                BorderBrush="Red"
                                BorderThickness="5">

              </Border>
          </StackPanel>
 </ControlTemplate>

x:name不起作用。

以下内容应该为您提供Canvas元素

(this.Template.LoadContent() as FrameworkElement).FindName("myCanvas") as Canvas

(this.Template.LoadContent() as FrameworkElement).FindName("myCanvas") as Canvas
