i want to add columns to the grid dynamically and at the same time that should be rendered in the edit mode. Please refer the sample GRID->EDITING GRID DATA->ROW TEMPLATE. Here the columns are fixed. Can someone give me tips to implement this logic?
This feature is not available in the grid control. Not sure about the exact scenario, but one way to do it would be to have column hidden when the page initially loads, and show the column upon certain user action when you want to actually have add a column.
Or use an update panel and when you want to add a column do a server post add a column to the datasource and the Ajax call will finished the grid will show the newly added column within the datasource.
