Resize Radgridview to fit the Columns width after datasource being updated

If you set AutoSizeColumnsMode to GridViewAutoSizeColumnsMode.Fill, the grid will be restricted to the size of its parent control it is put into (e.g. a Panel). Therefore, you can only adjust the columns width inside the restricted grid size by looping through all columns and calling column.BestFit().

To adjust the size of the grid itself, you need to set AutoSizeColumnsMode to GridViewAutoSizeColumnsMode.None whereby a horizontal scrollbar will appear if the grid size will get larger than its parent control.

Hello mansouri,

As M S mentioned, you can try using the BestFitColumns() method and pass BestFitColumnMode.AllCells enumeration as parameter. You could check the Resizing columns programmatically help article for more information regarding this method.
