In your click event if you set the textbox.Text property to strig.empty it's not work ?

Answer 3

After you save your data with the click button you can set the textbox.text = ""

EDIT: After your comment that textbox.text = "" is not working....

When you hit the refresh it sounds like it is resubmitting your work again. Try just reloading the page by browsing to your page again.

Also be sure to check that you aren't saving your data on every postback but just on the button click event.

Do you have any code in your page load event?
