  Hi 
  
  I have an application that has been written over the past 4 years. My company has now purchased RadControls for WinForms and so I am going to slowly convert it screen by screen.
  
  In the meantime though I have a function that is called by all current screens.
  
  SetupScreen(byval frm as form)
  
  I want to do different actions if the form is a Telerik RadForm. How do I know if the frm passed to my function is the standard form or a telerik form? Hopefully without changing the signature of my function "SetupScreen"
  
  Cheers

  Hi Simon,

  Thank you for writing and thank you for choosing RadControls for WinForms.
  
  In order to understand whether the passed form is a RadForm descendant or not, check whether the type of the frm variable is RadForm:

  Private Sub SetupScreen(ByVal frm As Form)

      If TypeOf frm Is RadForm Then

          'Your new logic

      Else

          'Your existing logic

      End If

  End Sub

  
  I hope this helps. Write back if you have additional questions.
  Kind regards,
  Nikolay
