Refresh the main page on close of popup window

[CPK]

I am opening the popup window with the below code from Server side

var url = string.Format("../UserPopup.aspx?user_Ids={0}&fromDate={1}&toDate={2}", user_Ids, fromDate, toDate);
string script = string.Format("function f(){{openDialog('{0}', {1}, {2}, {3});Sys.Application.remove_load(f);}}Sys.Application.add_load(f);",
                                     url,
                                     "true",
                                     1000,
                                     300);
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "someKey", script, true)

Below is the code for closing the popup window from javascript. The below code is not working.

function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow)
                oWindow = window.radWindow;
            else if (window.frameElement.radWindow)
                oWindow = window.frameElement.radWindow;
            return oWindow;
        }

function Close() {
var result = window.confirm("Are you sure you want to close the window!");
if (result == true) {
    var oWindow = GetRadWindow();
    oWindow.argument = null;
    oWindow.onunload = refreshParent;
    oWindow.close();
    return false;
    }
 }

 function refreshParent() {
     window.opener.location.reload();
 }

How can I close the popup window from client side and refresh the parent page?

 

FYI: I am using RadWindow as popup for this.

Hi,

You should use the OnClientClose event in the main page: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/client-side-programming/events/onclientclose. The article also shows how to properly pass an argument to the event handler.

I am getting the below error when I placed the main page code in debug mode

An exception of type 'System.ApplicationException' occurred in System.Web.dll but was not handled in user code

Additional information: Response.Redirect cannot be called in a Page callback.

Also, I want it to open only on clicking of button from Server Side. Now it is opening the page on open of main page.

Hello,

This error indicates that the Response.Redirect() method was called during partial page rendering which is not supported by the MS AJAX framework. You can find a solution through RadAjaxManager here: http://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/how-to/redirecting-to-another-page. Or you can just register a script yourself.

As for the RadWindow reopening—you need to ensure the code that opens it is not called again after the postback and that its VisibleOnPageLoad property is not set to true: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server.
