Oh. You asked about how to send parameters to popup window on asp.net 2.0 pro forum. Here's an example for that:
Code:
<script language="javascript" type="text/javascript">
function popUpWindow(id){
window.open('popup.aspx?id=' + id,[...],[...])
}
</script>
<asp:Button runat="Server" Text="Foo" OnClientClick='<%# Eval("ID", "popUpWindow({0}); return false;") %>' ...>
