How can I delete rows from datagrid control

hi all, I want to delete rows from datagrid control on clicking a button. So I gave datagrid.SetDataBinding( null, null ); It is deleting all the rows, but it gives the following exception. Could any one give me a solution for this ? System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Windows.Forms.DataGrid.GetCellBounds(Int32 row, Int32 col) at System.Windows.Forms.DataGrid.GetCurrentCellBounds() at testdatagrid.OnPaint_datagrid(Object sender, PaintEventArgs e) at System.Windows.Forms.Control.OnPaint(PaintEventArgs e) at System.Windows.Forms.DataGrid.OnPaint(PaintEventArgs pe) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) regards, lat.

Before you reset the datasource, try setting the currentcell to 0,0. this.dataGrid1.CurrentCell = new DataGridCell(0, 0);
