RadGrid Edit Template

[Varun]

Hi,

We have a dropdown and add button inside edit template of radgrid column, We have a functionality wherein inside the edit mode of a row of radgrid we populate the dropdown and then on clicking the add button open a radwindow to add a new item to dropdown. When the radwindow is closed the dropdown inside the edit template should refresh and show this new item.

Can someone please guide me in achieving the above functionality.

Thanks
