I set the data source of my radGrid to a dataset (which I saved in the session). I turned on AllowAutomaticUpdates and EnableViewState, implemented NeedDataSource, installed DatakeyNames, etc. (See code below)
However, when I click the “Change” button and make changes and click the “Refresh” link, the record does not update and does not exit the editing mode ... it just remains in the editing mode and no error occurs.
So the question is ... does anyone know if radGrid with EnableViewstate can even support AutomaticUpdates, so changes to the grid will automatically be inserted into the dataset to which it is bound?
You might think that you can read the documentation, but I could not find the final answer.
thanks
