Object doesn't support property or method 'add_show'

[Suzy]

Hi

I'm using add_show from Radwindow but sinds installing version UI for ASP.NET AJAX Q1 2015, I get following error :

Object doesn't support property or method 'add_show'


This is the javascript function I use it in it:

function openChildDialog(url, wndName, title) {
    if (!url)
        url = "errorPage.aspx";
    if (!wndName)
        wndName = "popup_" + Math.random();
    var currentWnd = GetRadWindow();

    var browserWnd = window;
    if (currentWnd)
        browserWnd = currentWnd.BrowserWindow;
    setTimeout(function () {
        browserWnd.add_show(returnDataToParentPopup);
        var wnd = browserWnd.radopen(url, wndName);
        wnd.__parentBackReference = window; //pass the current window object of the page that opens the dialog so it can be used later

        if (title)
            wnd.set_title(title);
    }, 0);

Can someone please help me? It is urgent because no window is opening in my production environment!

Kind regards

Suzy

Hi Suzy,

This should never have worked, because the browser window object does not have an add_show() method, only RadWindow instances do. Moreover, you should not add handlers to an instance created in the main page from inside the iframe. These are two different contexts and this can break. Please refer to the code library that explains how to create parent-child relationships between windows for details on how to do this properly by using the events of the RadWIndows in the proper context.

HI Marin,

I used that page to implement this???

Hello Suzy,

Here is the function from the code library:

function openChildDialog(url, wndName, title) {
    //in case of erroneous arguments, add some error handling and prevention
    if (!url)
        url = "errorPage.aspx";
    if (!wndName)
        wndName = "popup_" + Math.random();
    var currentWnd = GetRadWindow();
    var browserWnd = window;
    if (currentWnd)
        browserWnd = currentWnd.BrowserWindow;
    setTimeout(function () {
        var wnd = browserWnd.radopen(url, wndName);
        wnd.__parentBackReference = window; //pass the current window object of the page that opens the dialog so it can be used later

        if (title)
            wnd.set_title(title); //you can pass more parameters for RadWindow settings, e.g., modality, dimensions, etc.
        //you can even add arguments that will pass data from the parent to the child as shown here
        //http://www.telerik.com/help/aspnet-ajax/window-programming-using-radwindow-as-dialog.html
        //in the On the Dialog Page section that shows how to access custom fields in the RadWindow object and use them.
        //of course, you can also use querystrings in the URL.
    }, 0);
}

The add_show() call is not part of it.

I was just checking the post again and indeed that line is not in your example.  I know when I implemented it I have tested a lot of different scenario's and I think that part is from a test that I forgot to remove or something like that.

Sorry for that!

I will remove that line and check if everything is still working..
