I'm sure this has been asked a million times, but I did a yes no search and got nothing. Anyway, I'm sorry.
I just want the buttons to be Yes and No buttons, and of course the header and content as simple text. But I'm still getting OK and Cancel buttons with the following code:
DialogParameters dp = new Telerik.Windows.Controls.DialogParameters
Header = headerText,
Content = message,
Do I really need to add a template to get this to work as in the following article?
