Hi one Selected index change event you need to rebind the Grid and hide the column or visible the column as per selected value.like. 1. Grid templeted set the visibility in column and bind with boolean values. 1. catch the event on dropdown. 2. apply the visibility column value and set the true or false. 3. bind the grid view again.
