Dear deepu As you said AJAX Modal popup control is the best to show your Popup to the user. As your wish it will show an YES or NO sequence to user before he gets in to the Home page. But there are some things to note 1: if the browser does not support JavaScript, the pop-up will not work .So the user's web browser should compatible with javaScript. 2:Ajax is not a programming language,it's just an extension,rather a javascripted extension 3:The user might have pop-up killers running that close the window the moment it’s opened You can cover all that probs with your page's source <a href>
