How to extend the Telerik theme for a custom control

[Patrick]

Hello,
I have a scenario where I will leave the user change the theme of the application, selecting one of the available Telerik themes.
But I have a custom control that also needs to be themed. I don't want to modify the Telerik defined themes, because it could be complicated when a new version of the RadControls is available.
What would be the best option for this:

1. Define theme files for the custom control and load them at the same time as the Telerik theme is loaded (how to do this?)
2. When the custom control is created, detect the current application theme and set the control theme at this time.

Hi,

Create two resource dictionaries that contain implicit styles for your control. When you are applaying a telerik theme, merge one of these two dictioanries to your application resource. For example you could call:

Application.Current.Resources.MergedDictionaries.Clear();
Applicatin.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = ......

This would apply different implcit styles on your control at runtime.

Implicit styles now work for telerik controls too. You could check how you could apply implicit styles to Telerik controls here.
