  I have a VB.NET winforms application using C1Ribbon and C1BackStageView. Suppose the backstage view is closed and the user clicks the tab to open the backstage view. Is there any way to perform validation prior to opening the backstage view?

  Something like:

  Home tab clicked to open backstage view
  
  If (validation passes) then
  
  Open the backstage view
  
  else
  
  Do not open the backstage view
  
  end if

  I can’t seem to to figure it out via C1BackstageView.DropDown or any other of the C1Ribbon events.

  Thanks,
  
  Andrew

  Hi Andrew,

  You can achieve your requirement by using the MouseDown event of the C1Ribbon. In the event handler, you can check if the mouse is clicked on the “Application menu button” and if so, set the C1BackstageView.DroppedDown property on the basis of your validation.

  Please see the attached sample project showing a simple implementation of the same. In the project, the validation results are determined by the checked state of the checkbox.
