Receiving the error: "Insert Item is available only when grid is in insert mode." Shown at the end of this post. I have a grid with 3 text boxes and 3 dropdown lists. When I click a link " Add new item" it calls the RadGrid1_InsertCommand which would add a blank record to my data source and then I rebind. I do not modify any of the controls directly just the data source and rebind. Suddenly I have started to recieve this error and I don't understand what has changed for me to start getting this error. I've had this working fine. Please provide any insight you may have.

Thanks Pavlina,
Setting e.Canceled = true right before the bind did the trick. I missed that post in my search. Not sure why all of a sudden I have to do this, but thanks, your help is appreciated.
