Hi,

The ClassDiagram example defines the class shape inside <style> definition. I need now dynamically access one TextBlock inside the definition as I need to set the text according to user input. I'm having hard time to do this as following does not work:

private void NewClass_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)

{

ClassShape newClass= new ClassShape() { Content = "Class1", Position = new Point(300, 120) };

//newClass.ApplyTemplate();

var textBlock = newClass.FindName("TypeName") as TextBlock;

newClass.Loaded += this.OnNewClassLoaded;

this.diagram.Items.Add(newClass);

}

This is absolutely driving me crazy, so any help would be much appreciated.

The definition of ClassShape is something like:

<Window.Resources>

<Style TargetType="local:ClassShape">

<Setter Property="IsCollapsible" Value="True" />

<Setter Property="IsResizingEnabled" Value="False" />

<Setter Property="MinHeight" Value="100" />

<Setter Property="MinWidth" Value="100" />

<Setter Property="Padding" Value="15 5" />

<Setter Property="Width" Value="150" />

<Setter Property="Height" Value="Auto" />

<Setter Property="HorizontalContentAlignment" Value="Left" />
