How to force the grid to focus the next row when Tab or Enter is pressed on the last column cell

XtraGrid 2 and 3 provide an option to support this behavior: the AutoMoveRowFocus option of the GridView.OptionsNavigation property. The option is activated by default.

In XtraGrid 1 this can be implemented using the ProcessGridKey event of your grid control. Simply check which keys have been pressed via the e parameter passed to the event. Use the sender parameter to obtain your GridControl object, its KeyboardFocusView property to access the view which receives keystrokes and the view’s FocusedColumn and FocusedRowHandle properties to determine which cell is currently focused.

	
[C#]
private void gridControl_ProcessGridKey(object sender, System.Windows.Forms.KeyEventArgs e){

 DevExpress.XtraGrid.GridControl gc = (DevExpress.XtraGrid.GridControl)sender;

 DevExpress.XtraGrid.Views.Grid.GridView gv = (DevExpress.XtraGrid.Views.Grid.GridView)gc.KeyboardFocusView;



 if(!e.Shift && (e.KeyCode == System.Windows.Forms.Keys.Tab) && (gv.FocusedColumn == gv.GetVisibleColumn(gv.VisibleColumnCount -1))){

   gv.FocusedColumn = gv.GetVisibleColumn(0);

   if (gv.FocusedRowHandle != gv.RowCount - 1)

     gv.FocusedRowHandle += 1;

   gv.ShowEditor();

   e.Handled = true;

 }

 if(e.Shift &&  (e.KeyCode == System.Windows.Forms.Keys.Tab) && (gv.FocusedColumn == gv.GetVisibleColumn(0))){

   gv.FocusedColumn = gv.GetVisibleColumn(gv.VisibleColumnCount -1);

   if (gv.FocusedRowHandle != 0)

     gv.FocusedRowHandle -= 1;

   gv.ShowEditor();

   e.Handled = true;

 }

}
