Hi Deepa Sudhir, You didn't mention in which event of the page, you are binding the data to the dropdown. I assume you are binding the data in the Page_Load event. And, you have set AutoPostBack property of the dropdown to True. In general, you should bind the data only in the initial request and not in the postbacks. So, you should write the databinding code in the "If (!isPostback)" condition. If you don't write the code in the above specified condition, the binding logic will fire for every postback and the code in the SelectedIndexChanged will not work though the event gets fired. Hope it helped. Thanks, Prawin

Dear Deep sudhir, I think your not setting page loading time your get the value to selected index box right?. So you can set the value to your selected index box use Jquery or Java script and validated It. Thanks,
