Modal dialog will not open in IE7 or FF - fine in IE8 and Chrome

[William Mace]

We are encountering a strange browser issue.  We have a page that checks for the existence of a querystring on page load.  If it does not exist, the page_load event calls the following:

                RadAjaxManager1.ResponseScripts.Add("OpenDialog();");

This is the javascript called:
        function OpenDialog() {
            var url = "dialogs/NewDialog.aspx";
            var windowName = "NewDialog";
            var window = GetRadWindowManager().getWindowByName(windowName);

            modalWindow = GetRadWindowManager().open(url, window);
            modalWindow.set_width(400);
            modalWindow.set_height(200);
            modalWindow.set_modal(true);
            modalWindow.center();
            modalWindow.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Close);
            modalWindow.setActive(true);
        }

This works fine in IE8 and Chrome.  It does not open the modal window in IE 7 or FF 3.6.8.

BUT - as soon as I add a debug statement in the javascript like this:
        function OpenDialog() {
            alert("We are here");
            var url = "dialogs/NewDialog.aspx";
            var windowName = "NewDialog";
            var window = GetRadWindowManager().getWindowByName(windowName);

            modalWindow = GetRadWindowManager().open(url, window);
            modalWindow.set_width(400);
            modalWindow.set_height(200);
            modalWindow.set_modal(true);
            modalWindow.center();
            modalWindow.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Close);
            modalWindow.setActive(true);
        }
It starts working fine in all browsers.

Can anyone help me out as to where I am going wrong?  Thanks.

Hi William,

It looks that the JS code is called before the controls are fully loaded on the page in such scenarios. I would suggest to either call the JavaScript code with a small timeout, or to use the Sys.Application.Load event and call the code there.
