I have a form with a grid in it that uses a LinqDataSource. The Selecting event is wired up to return the number of rows. I use a RadAjaxManager and a RadAjaxLoadingPanel. However, when I click on a paging control the grid "flashes" and the loading "wheel" does not appear like the 300,000 Linq demo shows. The paging does work though. How do I make the loading stuff work? I have supplied the code for a cutback version of what I am doing in a real web app.
