Opening a window with an external page via JavaScript shows a blank page, raw HTML work though

[paul-2011]

Hi, I'm able to load external pages inside a window when I use html components but when using Ext.Net components the window displays blank, could you please take a quick look at the code snippet bellow?
I can load just the external page on the browser and it displays my Ext.Net components without a problem.
I'm using Ext.Net 2.3.
Thanks

new Ext.Window({
                id: "wndExternal",
                title: "External",
                width: 640,
                height: 480,
                maximizable: false,
                minimizable: false,
                resizable: false,
                modal: true,
                closeAction: 'close',
                autoLoad: {
                    url: "externalwindow.aspx", mode: "iframe", showMask: true
                }
            });

Your script is incorrect
If you not sure what script need to use then just create widget in aspx, run the page and see generated script

Hi Vladmir, thanks for point out that the script is no good, in fact it used to work with older versions of Ext that I played with.
Here's a good script for ExtJs4 that I just found:

new Ext.Window({
    title : "iframe",
    width : 300,
    height: 300,
    layout : 'fit',
    items : [{
        xtype : "component",
        autoEl : {
            tag : "iframe",
            src : "http://www.yahoo.com"
        }
    }]
}).show();
