Hi,

How can i control CTRL+X or CTRL+V in KeyDown Event...

Thanks,
Surti

Hi Surti,

To control the +V,+C keystroke in KeyDown event, you need to find the keystroke and set e.Handled = true to cancel the default behavior. Here is a code snippet to show this.

private void gridControl1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
Keys modifierKeys = Control.ModifierKeys;
Keys keyCode = e.KeyCode & Keys.KeyCode;
bool controlKeyDown = (e.Modifiers & Keys.Control) != Keys.None;
bool menuKeyDown = (e.Modifiers & Keys.Menu) != Keys.None;
switch (keyCode)
{
case Keys.V: // +V
if (controlKeyDown && !menuKeyDown)
{
Console.WriteLine("+V Pressed");
e.Handled = true;
}
break;
case Keys.C: // +C
if (controlKeyDown && !menuKeyDown)
{
Console.WriteLine("+C Pressed");
e.Handled = true;
}
break;
case Keys.X: // +X
if (controlKeyDown && !menuKeyDown)
{
Console.WriteLine("+X Pressed");
e.Handled = true;
}
break;
}
}
}

Thanks, i had some similar but it doesn't work well when +X, +V or +C are pressed because the value of KeyCode is "Control", not "X", "V", or "C".
Nevertheless, when any other key is pressed, the value of keycode is correct.

Hi, the code you sendme doesn´t work well because when i press "CTRL" with one of these keys (X, V or C) value of keycode is "Control", not "X", "V" or "C". Do you know why???

Thanks,
Surti.

Hi Surti,

We tried to reproduce this in V4.x by just implement KeyDown event in a GridControl, but could not get this issue. Maybe I am not following the steps that you are doing. Attached sample working fine here. Can you post a small sample showing this problem or tell us how to see it in the Browser sample/Attached sample?

Here is a sample for implementing it.
GC_KeyDownevent.zip

If you can provide more information, we can try to suggest some solution.

Hi,

I have Essential Suite 1.5.1.1.
I have same code that you send me but when i press the combination of CTRL with one of these three keys, the value of keycode, in keydown event, is "Control".

Previosly i had configured following properties of GC,

GridControl1.WantTabKey = false
GridControl1.NumberedColHeaders = false

Thanks,
Surti

PD: Sorry for my english.
