Disable textbox after typing in a value C#

Question

I want to disable a textbox after user has inserted a value. I have tried playing with the "KeyPress" property but the first digit I type in is also the "KeyPress", so it locks on the first character. Maybe I can get the textbox to lock after pressing Enter or using Tab. What will be the best way to do this?

what should happen when the user leaves the textbox but with out typing any value? — StackTrace

It sounds like you want to disable the box after the person leave it. (I assume that from your Enter/Tab option.) If so, look into the TextBox.LostFocus event.

Though, the "Best" generally depends on the customer requirement, I would do the disabling act on the Lost Focus event.

 private void textBox2_Leave(object sender, EventArgs e)
  {
       textBox2.Enabled = false;
  }

Thanks

Just use Leave event and in body assign Enabled to false;
