3 Textboxes If I add text to any 1 box it shows also in the other 2
Hi everyone. I have 3 TextBoxes on a form. What I'm trying to do is if text is added to any 1 of the 3 text boxes, it is also automatically shown in the other 2, without the need to click a button. If someone could help me out on this it would be very much appreciated. Thank you
