I have to track if F2 key is pressed on the form and perform some action after that ; I have written following code but nothing seems to happen

Code:

C#

private void Form1_KeyPress(object sender, KeyPressEventArgs e)
      {

          if (e.KeyChar == (char)Keys.F2)
          {
              MessageBox.Show("F2 pressed");
              //do something
          }
      }

Please suggest possible solution.....?

You will probably need to implement a keyboard hook:
Processing Global Mouse and Keyboard Hooks in C#[^]

or attach the handler to every control on your form. I would prefer the former.

Solution 2

The KeyPress event is not raised by non character keys and the only way to detect keys such as F2 is by the KeyDown and Keyup events msdn[^].

You'll also need to ensure that the KeyPreview property of the form is true.
