All,
I am using the latest RadGrid control. I am seeing an unusual error when "Inserting" a row. The error occurs when the grid's "insert" button is clicked. The Error: Sys.WebForms.PageRequestManagerServerErrorException: Cannot find cell bound to column with unique name 'EditCommandColumn'. However, 'EditCommandColumn' is clearly the first column in the grid! This is happening no matter which EditMode I choose...
What am I missing here please?!
