key press event on a ASP.net text box

donald

I got a ASP.net text box called textbox1 and a label called label1.

When a key is press in a text box i want it to up date the label with
what is in the textbox.

Label1.Text = TextBox1.Text;

But on a ASP.net text box there is no on key press event like this is
on a normal html text box but if i do the event in the normal html text
box i can't use the code in the .aspx.cs file.

How can i get round this?

Thanks

Donald
