Key Events

[dwedewdew]

Hi,

I'm using Syncfusion 4.3.0.30 windows.forms Grid Control in virtual mode.

I want to suppress certain key events triggered by the user (e.g. CTRL + X, CTRL + V, CTRL + Z, DELETE, etc.) if the grid isn't in editing state or the selected cell is readonly or static. Suggestions?

Thanks

Yours

I think you can use grid.CurrentCellKeyDown to get this behavior. Here is the idea.

//subcribe to the event
this.gridControl1.CurrentCellKeyDown += new KeyEventHandler(gridControl1_CurrentCellKeyDown);


//the handler code
       void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
        {
            GridControl grid = sender as GridControl;
            if (grid != null && !grid.CurrentCell.IsEditing)
            {
                if (e.Control)
                {
                    switch (e.KeyCode)
                    {
                        case Keys.V:
                        case Keys.C:
                        case Keys.X:
                            e.Handled = true;
                            break;
                        default:
                            break;
                    }
                }
                else if (e.KeyCode == Keys.Delete)
                {
                    e.Handled = true;
                }
            }
        }
