Solution 2

Check the source of the html. You are writing the values past the end of the actual html document (after the ). View the source of the response html and you might find the values at the end.

Good luck!

Then you need to put the value back in the textbox. Something like:
<input type="text" name="name" value="<?php print $_POST["name"]; ?>" />

Check this link...

or you can put values in viewstate then set them back to related control after page refreshed

AJAX can help to prevent refreshing of your page hence preserving your data!
