Try handling the CurrentCellKeyDown event to see if that does what you need.

void gridDataBoundGrid1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
    if((e.Alt && e.KeyCode == Keys.Z)
        || (e.Control && e.KeyCode == Keys.Z))
    {
        e.Handled = true;
    }
}

Hi,

Thank you for your answer.

I forgot to add that in my country RIGHT ALT + Z is a combination for a special character. I''d like this combination to put this special character in grida and not to generate undo/redo commands.

Hi Marek,

You can handle the CurrentCellKeyDown event and try to put the special character there itself. Try the code below.

void gridDataBoundGrid1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
if((e.Alt && e.KeyCode == Keys.Z) || (e.Control && e.KeyCode == Keys.Z))
{
string str = cc.Renderer.ControlText;
cc.Renderer.ControlText = str + "spl-char";
e.Handled = true;
}
}

Let us know if this helps.
Thanks,

Hi,
I tried your code.

cc.Renderer.ControlText is correct and contains special character.
But GDBG seems to catch the undo command anyway (although I set e.Handled = true) and any of my changes to cell value is being undone (rolled back by undo command) :(

PS

Maybe I should handle

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {}

But I can''t figure out how to check whether ALT+Z was pressed.

Hi Marek,

Please try the below piece of code.

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{			
    if(this.gridDataBoundGrid1.CurrentCell != null)
    {
	if((Control.ModifierKeys & Keys.Alt) != 0)
	{
	    if ((keyData & Keys.Z) == Keys.Z)
	    {
		Console.WriteLine("Hello");
		return true;
	    }
	}
    }
    return base.ProcessCmdKey (ref msg, keyData);
}

Let me know if you need any further assistance.
Thanks,

Hi,

Thank you - it works! However cell contents becames highlighted.

Could you please tell me how to make grid not to highlight the cell contents after I press ALT+Z

I replaced your line:
Console.WriteLine("Hello");

with

GDBD.CurrentCell.Renderer.ControlText += "spec-ch";

Regards,
Marek

Hi Marek,

Try adding the code below, this will help you.

///
this.gridDataBoundGrid1.CurrentCell.Renderer.ControlText += "spec-ch";

GridTextBoxCellRenderer tr = this.gridDataBoundGrid1.CurrentCell.Renderer as GridTextBoxCellRenderer;
tr.TextBox.SelectionStart = this.gridDataBoundGrid1.CurrentCell.Renderer.ControlText.Length;
tr.TextBox.SelectionLength = 0;
