Not sure when to use

[Rayne]

I would like to persist a RadGridView for visibility and order of columns per user between sessions. The GridView is on a User Control that is added to a RadTabControl at startup via Prism's RegionManager.  This UserControl/TabItem doesn't get removed from the TabControl until the application closes. 

When (which events) is the best time to load and save?

Hi Rayne,

 You can try Saving on Application.Exitt event and Loading RadGridView.Loaded event. If the loading in Loaded does not work, you can try load in Dispatcher.BeginInvoke(..). Please let us know if this helped you.
