loginname control value

Hi..
does anyone know how to get loginname control value in textbox

I am using loginname control after login,where it will display the username of the user.
Now i want to get that username value to textbox.
How do i suppose to do that?

Use this code:


        TextBox1.Text = LoginName1.FormatString;

where to put this code,i mean is it in text_changed?

Put this code. whenever you required.

you can put in page_load event if you want it page_load.

it is based on your requirement.

I put in in the page_load..but its not working..

It says :
The name 'TextBox1' does not exist in the current context

any code to add on?
