Overriding Control Template in a Custom Control Library not working

[Eric Bush]

I have the following derivation that includes the customary static constructor.

 

public class CustomRadDatePicker : RadDatePicker

 

 

static CustomRadDatePicker()

 

{

DefaultStyleKeyProperty.OverrideMetadata(

 

typeof(CustomRadDatePicker),

 

 

new FrameworkPropertyMetadata(typeof(CustomRadDatePicker))); // also tried RadDatePicker here

 

}

In the XAML for the controls template I have the following.

 

 

 

<Style TargetType="{x:Type SharedControls:CustomRadDatePicker}">
...

 

 

 

<Setter Property="Template">

 

 

 

 

 

 

<Setter.Value>

 

 

 

 

 

 

<ControlTemplate TargetType="{x:Type SharedControls:CustomRadDatePicker}">

Now when I use the control on a page it does not use the style I have set up but is using the Telerik style.
I have my derived control and its template set up in a WPF custom control library.
Is it allowed to override the Teleric Style?

Hi Eric Bush,

Thank you for contacting us.
 
You could override OnInitialized method, call the base OnInitialized and after that set the DefaultStyleKey.
For example: 

protected override void OnInitialized(EventArgs e)
        {
            base.OnInitialized(e);
            this.DefaultStyleKey = typeof(CustomRadDatePicker);
        }

I hope this helps!

Best wishes,
George
