I think it is a WinForms application since you say desktop app. So there are some events that you can use KeyUp, KeyDown or KeyPress.

You can use KeyDown event and define a global or static variable that holds how many times it enters that event before that click button is pressed.

KeyDown Event MSDN[^]

Good luck,

There is nothing standard to do that - we aren't generally interested in how a user entered the data, but what he ended up with.

You can do it: handle the KeyPress event for the TextBox and count the key presses:

C#

private int pressed = 0;
private void myTextBox_KeyPress(object sender, KeyPressEventArgs e)
    {
    if (char.IsLetterOrDigit(e.KeyChar))
        {
        pressed++;
        }
    }
