hi Sashibhusan Meher,

This is because you need to register the script once to DOM, Try doing the below things

write the window.open code in a javascript function
like

JavaScript

<script language="javascript">
function popUp()
{
window.open('detailsofjobseeker.aspx', '', '', 'height=200,width=400'); return false;
}
</script>

then in pageLoad()
write like this..

C#

protected void Page_Load(object sender, EventArgs e)
        {
         String name1 = "PopupScript";
         String text1 = "<script type=\"text/javascript\">popUp();";
         RegisterStartupScript(name1, text1);
        }

and while calling.. write like this

C#

btn.Attributes.Add("onClick", "popUp();");

it may work.

Thanks.
