//Event triggered to apply CellPadding.
this.gridGroupingControl1.TableControlPrepareViewStyleInfo += gridGroupingControl1_TableControlPrepareViewStyleInfo;
void gridGroupingControl1_TableControlPrepareViewStyleInfo(object sender, GridTableControlPrepareViewStyleInfoEventArgs e)
{
   if (e.Inner.ColIndex == 2 && e.Inner.RowIndex == 4)
   {
      e.Inner.Style.TextMargins.Left =25;
   }
   if (e.Inner.ColIndex == 1 && e.Inner.RowIndex == 5)
   {
      e.Inner.Style.TextMargins.Right = 20;
   }
}

'Event triggered to apply CellPadding.
Private Me.gridGroupingControl1.TableControlPrepareViewStyleInfo += AddressOf gridGroupingControl1_TableControlPrepareViewStyleInfo
Private Sub gridGroupingControl1_TableControlPrepareViewStyleInfo(ByVal sender As Object, ByVal e As GridTableControlPrepareViewStyleInfoEventArgs)
