The screen turns blank when window closed

[Kevin]

Hi,

I have encountered a problem when the window's close button is clicked, sometimes the whole silverlight application is turned to blank. Below is the function that i used to call up the window.

ShowWindow(New Page1())

 Private Sub ShowWindow(ByRef obj As Object)
      
        Dim Service As New Telerik.Windows.Controls.NavigationService
        Dim Window As New Telerik.Windows.Controls.RadWindow
        Dim WindowPanel As New Telerik.Windows.Controls.RadFrameContainer

        LayoutRoot.Children.Add(Window)
        Window.Content = WindowPanel
        Service = NavigationService.GetNavigationService()
        Service.RootPanel = WindowPanel
        Service.Target = Service.RootPanel
        Service.Navigate(obj)

        Window.WindowStartupLocation = WindowStartupLocation.CenterScreen
        Window.CloseMode = CloseMode.Close
        Window.Show()

    End Sub

Based on my testing, it only happen on Firefox. IE so far didn't happened.

Hello Kevin,

I suppose that the problem is related to a conflict between RadNavigation and RadWindow - could you please open a new support ticket and send us a simple project, that can be used to reproduce the problem. We will answer with a solution as soon as possible.

Kind regards,

I can make this problem happen with your demo: http://demos.telerik.com/silverlight/#Window/APC.  It happens in my application as well.  Our purchase and adoption of the Silverlight controls depends on reliable pop-up window manipulation.  I don't know if your demo app uses RadNavigation, but I certainly combine it with the RadWindow pop-ups.

Any status on this?

Thanks,
Tim Lucia

Hello Tim,

I shot a short movie trying to break the example you mentioned. Am I doing something wrong? I also tried the same things with Firefox, but again with no success.

Could you provide more details about your application, steps to reproduce the problem, or even the application itself, because it will help us to find the problem faster? Unfortunately Kevin did not sent us a sample, so we were unable to find the problem in his application...

Kind regards,

I will try to strip it down to make it post-able.  It's not really proprietary since we're just dabbling.  I just tried your demo again and couldn't break it.  I broken it twice yesterday.  I wonder - could it be related to debugging and Visual Studio?  I wasn't debugging this morning, but may have been yesterday.  I am always debugging when running my app.

[Tim]

It just happened to me again - with the debugger attached.  The Firebug console has the following errors - I am not sure they are all related - in fact I thing some of the older ones may not be.

Hello Tim,

Could you please, provide at least the steps to break the demo?

Sincerely yours,

So far, the likely scenario to make it break is to:

Run FireFox (3.0.11)
Debug a simple application so it starts in a tab in FireFox
In a second tab, go to the demo application
Navigate through all the various pop-up controls (alert, prompt, confirm)

The last two times I've seen it were under the conditions above.  Previous times likely under the same conditions, but I wasn't paying attention at that time, unfortunately.

Tim

[Valeri Hristov]

Hi Tim,

Thank you for the instructions. I was able to reproduce the crash. I found several forum threads in the Silverlight forums about a similar issue, that is related to controls that remove themselves from the visual tree (such as RadWindow) and which hopefuly will be fixed in Silverlight 3. I will look for a workaround in RadWindow while waiting for Silverlight 3 RTM, but I cannot promise anything at the moment.

Your points have been updated.

is there a way how to catch the error ?
thanks
Giovanni

I post my test on the web site http://www.softwhale.it/default.html
if you click on the page "CHI SIAMO" and in the read More button under "Edoardo" you can see the rad window
if you click several times to other pages and come back ( many click around) after a while the RadWindows make SL app. blanck screen

I ho can help you
ciao

[Tim]

I will chime in with the fact that I have not seen this in a while now.  I am running one of the dev builds though, 2009.2.724.1020.  Speaking of which, can I ship this with a demo/beta version of our product to a small handful of customers?  And while I am on the subject, any date yet for the SP1 release version?

Tim

[Miroslav Nedyalkov]

Hi Giovanni, Tim, 

After a some investigating about the problem we found out that it might be related to a problem between Firefox 3.0.* and Silverlight. We were unable to reproduce it with Firefox 3.5, latest Firebug and latest Silverlight.

The service pack should be released this week.

Little update on this matter.

I am running my app on Silverlight 3, latest Q3 release, and FF 3.5.5, and I still randomely get the error "value does not fall within expected range" and blank screen when I close a RadWindow.

This bug happens more often when I'm debbugging, but it also occurs on a normal runtime.

Any news about that particular problem ?

[Nikolay]

Hi,

We used to occasionally reproduce the problem on one of our developer's machines, but it has been a while since we weren't been able to reproduce the problem. We think that most probably the problem was caused by some plug-in in Firefox that we had removed. Could you please provide some more details about the browser's plug-ins you are running? Otherwise, we are shooting in the dark with this issue.

Sincerely yours,
Nick

Ok, well, here's what I could gather.

I must tell that it's pretty random, and does not happen very often

So, right now, I'm using Windows 7 pro, Firefox 3.6b4, RadControls Q3 1120, .NET 3.5, Silverlight 3 and Visual Studio 2008.

After trying open and close (through coding with .Show method) several time a window, my screen turned blank and here's the exception :

Erreur : Unhandled Error in Silverlight Application

I was running the debugger on Visual Studio 2008, here's the faulty code :

                RadWindow CubeWindow = new RadWindow();
                CubeWindow.Height = 480;
                CubeWindow.Width = 640;
                CubeWindow.WindowStartupLocation = WindowStartupLocation.Manual;
                CubeWindow.Top = 35;
                CubeWindow.Left = App.Current.Host.Content.ActualWidth - 640;
                CubeWindow.Content = new SilverCube.CubePage(env.Id_Contact, env.Id_societe, false, _wsApplicationClient);
                CubeWindow.Show();

And the xaml of the content of the RadWindow

            if (rotation)
            {

            }
            //Récupération des thèmes
            test.GetThemeAsync(this.id_contact);
            test.GetThemeCompleted += new EventHandler<GetThemeCompletedEventArgs>(test_GetThemeCompleted);

        }

        public CubePage(String query)
        {

            InitializeComponent();
            this.query = query;
        }

I really hope you can do something with that

Hello

I might have a lead related to the problem described above.

I was fighting with a "value does not fall within the expected range" on one of my radwindow when, searching the stacktrace on google, I found a post similar to my problem.

Do you think it might be possible that when the RadWindow closes (through the UI or the Close method), that a reference to the object RadWindow could still be retained by Silverlight. If that was the case, if someone tried to open a radwindow with the same name before the GC collected the memory, then, the Parent property of the initial radwindow would still be set.

Since a child can only have one parent at any time during runtime, that case would raise a "Value does not fall within the expected range" in the NodeKeyValueCollection.

I've managed to work around this exception by never recreate the window, only change its content and then Hide and Show it at will.

Hello Subileau,

It's good to hear that you solved the problem. Anyway we will continue investigating what caused it.

Well, I'm not saying that I've been completely able to work around it, as long as the open and close operations are handled in code, I can, but if the user close the radwindow from the UI (top right close button), there still is a chance that the exception could occur.

[Ludovic Gerbault]

This RadWindow problem is driving me mad, I can't solve it.

I tried everything I could think of, but I can't seem to be able to handle the error when the user closes the RadWindow through the UI.FYI
This "Value does not fall within the expected range" is always coming up randomly at some point during the runtime and crashes the whole thing.

Damn this is frustrating.

The thing is, I can also reproduce my problem directly in your demo. With a few manipulation of the radwindow of the demo (the radwindow and usercontrol example), the demo ends up crashing on Firefox.

FYI : I open Visual Studio and launch any project in debug mode, and then open and close repeteadly the RadWindow. Eventually, the demo crashes with the same error message as I get on my own application.

I can't release my application until this problem is solve, I really need a fix for this, or at least a hint on what's going wrong there.

I'm pretty sure it has something to do with two child controls with the same name on the same namescope, but I can't find it.

[Miroslav Nedyalkov]

Hi Subileau,

 The problem here is that we are unable to reproduce the problem at our side and it is really hard to debug an issue that cannot reproduce and if reproduced it doesn't happen every time. I'm really sorry that we cannot help with this.

Just as a suggestion - could you please try to install the latest versions of Firefox (if this is the browser in which the issue happens) and Silverlight 3 runtime. This might fix the issue as we are using the latest versions.

Best wishes,

Well, unfortunately, so am I, I'm running FF 3.6 beta RC2 and Silverlight 3 runtime

Have you tried running your demo whilste VS2008 debug mode is active ?

[Miroslav Nedyalkov]

Hi Subileau,

 I installed the RC2 version of Firefox 3.6 and couldn't reproduce the problem on the live demos site (http://demos.telerik.com/silverlight/#Window/Configurator), but I was able to reproduce it in debug mode. After that I started the application without debugging (Ctrl+F5) and the problem didn't happen again.

As this problem exists only in FF 3.6 RC2 and happens only in debug mode I guess it is a bug in FF and as it doesn't happen if you are not debugging I might be caused by the VS debugger.

This was the easiest way I could think of the reproduce the problem, the thing is that, in my application, this problem occurs (rarely I admit) during production runtime.

What bothers me is that I can't manage it or prevent application crash.

[Miroslav Nedyalkov]

Hello Subileau,

 We will continue investigating the problem and as soon as we have progress we will let you know.
