trap the click event for a button that is in the resourcedictionary

Answer 1

If you are trying to search inside of a resource dictionary, you should be using the function FindName(string), not GetTemplateChild(string).

Even if you are searching for a child control within the template of the current control, you should use Template.FindName(string, FrameworkElement templatedParent) not GetTemplateChild(string).

If this doesn't help, please expand you description.

If you have a code behind file, usually you can add the handler right in the XAML and have it attach to the code behind (even if the control is in a dictionary you can often do this).

I hope this helps.
