Hello!

I've spent couple of hours trying to figure out how to delete, update or insert data into database via RadGrid. Could you point me out what I'm doing wrong. What I'd like to accomplish is to edit the data via EditForm, insert data via "Add New Record" Command and delete the data.

I've been going through Telerik's documentation, but I'm totally lost.

Any help would be appreciated.
