I have a very basic grid with the ability to add records directly to it. When you click Add Record, you get a blank grid until a postback. If you click the foo button, you'll see the grid comes back in add mode. I tried adding an RadAjaxPanel and a RadAjaxManager, but neither fixed the issue.

Help!
