<asp:ImageButton ID="ImgExportPdf" Height="20px" ImageUrl="~/images/pdf-icon.png"
runat="server" ToolTip="Export To Pdf" OnClientClick="javascript:return open_win();" />

and the javascript is this:

<script type="text/javascript">
function open_win() {

new window = window.open("ReadPdf.aspx", _blank);

return false;
}

</script>

why are you returning false? try to return true and then see it works or not.
