Our development team has used Telerik WPF controls for our application under test. ** GENERATED CODE SUCH AS A UIMAP OR ELEMENT LIST IS PROHIBITED** Our automation approach is to write a class to identify the outer window and use either GetMatchingControls or GetChildren in an iterative fashion. One of the Telerik controls involves a Telerik GridViewCell that has an imbedded Calendar control. The GetChildren method of Microsoft UITest control yields a Microsoft.VisualStudio.TestTools.UITesting.WpfControls.WpfCell for the Telerik GridViewCell. I can't figure out a way to recast the cell as a Telerik GridViewCell. I need to recase because using he GetChildren method of the Telerik GridViewCell represented as a WpfCell is "blind" to the embedded calendar control.
