How to detect a key press?

  • 772

I know the event KeyPress, but I want it to detect the key being in any part of the program, I could put this event in all the elements of the program, but I want to know if there is a more efficient way to do this

c#

    There is a method that could solve the problem

    Form.ProcessCmdKey(Message, Keys) Method

    leaving something like this

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

     if (keyData != Keys.Enter) 
     {
         return base.ProcessCmdKey(ref msg, keyData);
     }

     //resto codigo

     return true;
}

    In this example it is detected if the enter key is pressed no matter where the focus is in the form

    This is a method, not an event, so you will see that the override, but it allows you to capture the keyboard events of the entire form
