How to get Keypress event in Windows Panel control in C#

Question

i want to get keypress event in windows panel control in c#, is any body help for me...

Answer 1

You should handle the Panel.KeyPress event.

Example

public void MyKeyPressEventHandler(Object sender, KeyPressEventArgs e)
{
    ... do something when key is pressed.
}

...

(MyPanel as Control).KeyPress += new KeyPressEventHandler(MyKeyPressEventHandler);

Answer 2

The problem is, that at first your main form got the KeyPress and will immediately send this message to the active control. If that doesn't handle this key press it will be bubbled up to the parent control and so on.

To intercept this chain, you have to in your Form.KeyPreview to true and add an handler to Form.KeyPress. Now you can handle the pressed key within your form.

Answer 3

"Panel" objects cannot receive the "KeyPress" event correctly.

I've created Panel overload:

public class PersoPanel : Panel

and used the overridden method ProcessCmdKey:

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

to intercept pressed keys:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    MessageBox.Show("You press " + keyData.ToString());

    // dO operations here...

    return base.ProcessCmdKey(ref msg, keyData);
}
