So you have not actually tried anything and you just want someone to write some code for you?

i want code for that
:doh:
It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
Members will be more than happy to help like this.

For now, you need to:
Option #1:
Handle/Validate it on client side itself. Use RequiredFieldValidator OR define a JavaScript onsubmit event of page where you check if the textbox has value or not

Option #2:
After page postback, in the submit event (if a button submitted the page), look for the text value and show a message in case value is nothing.

I would by far suggest option 1.
Try out and post specific issues if you have any.
