So I am trying to figure out how to build the code behind for the updatecommand on a radgrid where the records I senrt are saved in viewstate, and once the user clicks on "save" button on the form, those records are saved on the db along with other data on the form. I am not sure how to go about updating? when I click the "edit selected" button, the record on the radgrid either disappears or opens up blank in the edit form, and one i hit update...nothing happens. how can I do this?
