I have a scenario where I only want to unhide the pane when certain property of the document is true. For example: I have 3 panes A,B and C Panes A and C are visible. Active Pane should always be Pane A. By default pane (B) is hidden. Now when I set the IsHidden Property of the pane B to FALSE. Pane B now becomes the active pane. I still want Pane A to be the Active Pane, but show the Pane B in background. If I try setting the Pane A to be the active pane after Pane B is shown. It flickers which you can see here http://screencast.com/t/dGvU7UwUyYp Is there any way i can unhide the pane in background while the active pane remains the same without having this flickering scenario.
