I have a websplitter with 2 panes. Each pane includes an UpdatePanel. Inside each UpdatePanel is a WebDatagrid. The left WDG has selection/activation enabled and I want to reload the WDG on the right on the RowSelectionChanged event.

The target WDG updates when I use a button to fire the update, but not when it is the RowSelectionChanged event. Any help would be appreciated. Sample code is below:
