Hi George,
I performed a test based on your description but didn't reproduce the
problem on my side. I could set the Template property of a Thumb control at
run time.
The following is XAML:
<Window x:Class="WpfApp lication1.Windo w1"
xmlns="http://schemas.microso ft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microso ft.com/winfx/2006/xaml"
Title="Window2" Height="300" Width="300" Loaded="Window_ Loaded" >
<Window.Resourc es>
<ControlTemplat e x:Key="ThumbTem plate" TargetType="{x: Type Thumb}">
<Ellipse Width="20" Height="20" Fill="Blue"/>
</ControlTemplate >
</Window.Resource s>
<StackPanel>
<Canvas Name="myCanvasS tretch" Width="200" Height="200"
Background="Pin k">
<Thumb Name="myThumb" Canvas.Left="80 " Canvas.Top="80"
Background="Blu e"
Width="20" Height="20" />
</Canvas>
</StackPanel>
</Window>
The code in the Window1.cs file:
public partial class Window1 : Window
{
public Window1()
{
InitializeCompo nent();
}
private void Window_Loaded(o bject sender, RoutedEventArgs e)
{
this.myThumb.Te mplate = TryFindResource ("ThumbTemplate ") as
ControlTemplate ;
}
}
Build and run the application. The Thumb control is rendered as a blue
ellipse.
Is there any difference between your code and mine?
Sincerely,
Linda Liu
