I have a radgrid that inherits it hierarchy from a System.Data.DataSet. When I make a change I update the database from which the DataSet gets its data and rebuild the grid as this answer suggests. The first time the update always runs as expected and updates in the grid. After that after varying amount of changes( I can't seem to figure out exactly which one causes this) I get the following error:
JavaScript runtime error: Unable to get property 'get_element' of undefined or null reference
I hope you are able to help
