Question

What code should be used to focus a Textbox?

I am creating a system, where I need that when the client keystrokes ESC, the focus of the textbox is lost.

How do I do?

Answer 1

You need some other focusable control to change the Focus, you can set to a label, for example:

private void key_pressed(object sender, KeyPressed e)  
{ 
  this.ActiveControl = label1;       
}

or for a NULL

private void key_pressed(object sender, KeyPressed e)  
{ 
  this.ActiveControl = NULL;       
}

Answer 2

It is possible to do this two ways:

1. Change focus to a label, for example, since this does not remain user-friendly.
   In my view, this is the best idea because it makes it possible to choose the next control that will receive focus when clicking Tab    .

2. It is also possible to change the active control of the form for null.

   this.ActiveControl = null;
