Adding Events To WinForms?

Question

I have a TextBox on a WinForm and I want to execute some code every time someone presses a key inside of that TextBox. I\'m looking at the events properties me

Answer 1

These answers will have visual studio generate the event and bind it behind the scenes in the Designer.cs file.

If you want to know how to bind events yourself, it looks like this.

MyTextBox.KeyDown += new KeyEventHandler(MyKeyDownFunction)

private function MyKeyDownFunction(object sender, KeyEventArgs e) {
    // your code
}

If done this way, the new KeyEventHandler() part is optional. You can also use lambdas to avoid boilerplate code.

MyTextBox.KeyDown += (s, e) => {
    // s is the sender object, e is the args
}
