I have a RadGrid bound to an EntityDataSource on a page that I also have a RadFilter. If I press enter when focus is in one of the RadFilter input fields, it causes the grid to trigger an export in whichever format is first in the CommandItemSettings. I've tried disabling enter with this method - http://www.telerik.com/help/aspnet-ajax/grid-cancel-enter-arrow-keypress.html on the RadGrid and it didn't help. The RadFilter doesn't have the same events, so I couldn't add it there. It also makes no difference if I position the CommandItem at the top or bottom. This is with the RadFilter positioned below the RadGrid.
