Hi Mitul,
You need to catch the gridGroupingControl.TableControlResizingColumns event to avoid the columns getting hidden completely when resizing. Below is the code snippet.
void gridGroupingControl1_TableControlResizingColumns(object sender, GridTableControlResizingColumnsEventArgs e)
{
if (e.Inner.Reason == GridResizeCellsReason.MouseUp && e.Inner.Width == 0)
e.Inner.Cancel = true;
}
Similiarly, for rows you could catch the grid.TableControlResizingRows event handler.
Have a nice time.
