I have a user.aspx page that has grid and combobox, which combobox has static Please Select and dynamic items comes from datasource.. Grid gets populated based on the value selected from combobox. When row gets clicked windows opens up (windowUser.aspx) we can update that selected record, when it is updated windows closes and page goes back to user.aspx page, but it shows Please Select again.. I want it to show the value user selected, basically combobox should retain the value when return the page after updating the record from windows.aspx page.. what I need to do?

when you say "window opens up" you are changing pages, correct?

Two solutions:

1) make your user UI a popup menu that belongs to the orginal page, and use ViewState to hold the selected user.
2) persist the selected user value elsewhere (e.g., to Session variable) and initialize the combox box on the user page as approrpriate

Syntax may not be exact...

Session["userID"] = ComboBox.GetSelectedValue();

ComboBox.SetSelectedValue(Session["userID"]);

how about something like this??

passing  selected country combobox  value from user page on code behind to second page(window) and  
on javascript  when window closes pass that value back to first page again..
 winUser.NavigateUrl =xxx.aspx?id=" + dataKey["id"].ToString() + "&countryID ...

and how can I add add countryID to javascript function below after user.aspx?

 function OnClientClose(sender, eventArgs) {
                    var arg = eventArgs.get_argument();
                    if (arg) {
                        radalert("A custom argument was passed. Its value is: " + arg);
                    }
                    else {
                        window.location.href = "user.aspx";
                    }

If you want to do it that way you have to access the combobox from jscript by its ID and get its selected value.  You have several solutions - syntax is up to you :)

probably you are not using postback on popup close... use postback method, and make sure you rebind your data to your control based on posted values...
