R – Telerik RadGrid opening an extra popup edit form when pressing “enter” from a popup form for inserting

I have a radgrid that uses the popup edit mode with a custom edit template. The edit form upon pressing the enter key will insert a new item into the grid. I go in and add an item. This successfully inserts. Then I go to add a second item: The popup form appears. I enter in my data and press the "enter" key to insert the item. This time, instead of inserting the item, my edit form will clear out the data I entered and open another popup edit form to allow editing of my previously inserted item (from the first time). I now have 2 popups (1 for inserting, 1 for updating).

If I click the insert button instead of pressing "enter", then everything works ok. From what I can guess is that it is thinking that I'm pressing the enter on a selected row on the grid. How do I prevent it from triggering the "edit" event while I'm trying to insert?

Thanks
