We have a situation where we need to display a particular ContentPane (in a TabGroup or DocumentContentHost) without causing the application to steal the focus. We are currently using latest NetAdvantage WPF v9.2.

Unfortunately, ContentPane.Activate() internally calls Window.Activate() on the Window that contains the ContentPane, this causes the application to get focus if it does not already have it.

Is there any way to make a ContentPane visible without causing the application to steal focus?

Below is a simple test that shows the problem. When this window is running the active pane is changed every second and each time the active pane changes the application gets focus (try clicking on another application while it is running).
