You need TextChanged event. You might also want to check MaskedTextBox control.

Use a maskedtextbox control. That will solve your problem.

http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.mask.aspx

hook up the event on the textbox:

private void txtBOX_KeyPress(object sender, KeyPressEventArgs e)
{

}

You can use textchange event, or a mask. keypress as mention above is the ugliest way to do it, but the most powerfull.. you can "play" with the input data as you wish.

use these code in your key press event

if(!char.IsLetter(e.keyChar) && e.keyChar!=8)
{
e.handeled=true;
}  

These will prevent your text box to accept any thing else alphabets and the backspace button.
