Hi, I have implemented a WPF application that displays various pages. I have the following code that is executed on one of my pages after a user logs in. This same code is executed when the user returns to the page: If myUser.IsInRole("Master") Or myUser.IsInRole("Administrator") Then myRadGridView.SelectionMode = SelectionMode.Multiple Else myRadGridView.SelectionMode = SelectionMode.Single End If After logging in the myRadGridView grid behaves as if it is SelectionMode.Single even though my user is in the role "Master" and the code branch above is executed to set the myRadGridView grid into SelectionMode.Multiple. That being said, if I leave the page and come back to it, the same code is executed and the myRadGridView grid finally behaves as it should be in SelectionMode.Multiple. How do I fix get this to work? Thank you.
