[Solved] Can't close window after maximizing it in ie.

[Darren]

Hi,

I have a problem in ie where after maximizing the window and the trying to close it, the window returns to its original size and poistion and loses the close and maximize buttons?

The window loads a web page after selecting an option from a context menu, no issue in Firefox or Chrome.

Error below
Line: 2359
Error: 'sender._popupBehavior' is null or not an object

Thanks
Darren

Adding the below code resolved this problem.

The only case where I have seen similar behavior is when a version prior to Q1 2011 is used with IE9 - IE9 introduced a breaking change in the way iframes are created and handled and therefore versions of the RadControls for ASP.NET AJAX that have been released before the IE9 release do not support this browser. If you are using an older version you probably get a DOM exception error (5) when you open the RadWIndow initially. If so - please upgrade to the latest version (currently 2011.2.915 - Q2 2011 SP1) and see if the issue persists.

There is, however, one omission in the way the OnClientCommand event is handled - the popup behavior modifications need only be done if the command is not close:

functionOnClientCommand(sender, args)
{
    if(!args.get_commandName() == "Close")
    {
        args.set_cancel(true);
        sender._popupBehavior._manageVisibility = false;

        args.set_cancel(false);
        setTimeout(function()
        {
            sender._popupBehavior._manageVisibility = true;
        }, 200);
    }
}

The original code would, indeed, prevent the RadWindow from closing, yet it should not result in an error.

If you are still experiencing difficulties please modify this test page so that it reproduces the described behavior reliably and send it back to me so I can debug it and see what is going on. A screen capture or detailed instructions showing how you recreate the error would also be helpful.

All the best,
