handling function key press

I have a C# form with 5 buttons. The users enters the information and depending on the press of a function key, a specific action is performed. F9-Execute Order, F6-Save, F3-LookUp.

I have added the foolowing code:

OnForm_Load

this.KeyUp += new System.Windows.Forms.KeyEventHandler(KeyEvent);

and 

private void KeyEvent(object sender, KeyEventArgs e) //Keyup Event 
    {
        if (e.KeyCode == Keys.F9)
        {
            MessageBox.Show("Function F9"); 
        }
        if (e.KeyCode == Keys.F6)
        {
            MessageBox.Show("Function F6");
        }
        else
            MessageBox.Show("No Function");

    }

but nothing happens

Thanks

You need to set

KeyPreview=True

for your form. Otherwise key press is swallowed by the control that has focus.
