How to access a UI elment in custom control template?

Question

Inside this custom control's control template

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

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

How can I access the Canvas from the class

 public class CustomLineGraph : Control
        {
           myCanvas.AddChild(obj);
        }

x:name doesn't work.

Answer 1

The following should give you the Canvas Element

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