Well, keyPress is an event. And it's triggered by pressing keys. That's it. It's up to you to use this event. What's your prob? What do you want to achieve?

Solution 1

Textbox is having KeyPress event.
So you can write your logic inside that event.

Solution 4

public textbox1_KeyPress(object sender,KeyPressEventArgs e)
{
e.KeyChar=char.ToUpper(e.KeyChar);//converts the entered char to upper
}

if you want to do any validations of the pressed key,you can do it in keydown event and pass a boolean value to keypress event,based on the bool value you can perform the operation you need

Hope it helps!!

Good Call.

Girish, here is my advice: always show how the handler is added to the event. I come across few questions when the users write some code like in your sample but fail to understand it won't ever called by itself unless added to the event instance...
