SL4 upgrade - problems again with windows newly opened window appearing behind previously opened window

[Giancarlo Aguilera]

Hello,

I am using version of SL 4 RAD controls. I am having the same problem described here (http://www.telerik.com/community/forums/silverlight/window/modal-dialog-appearing-behind-parent-radwindow.aspx#0). In SL3 the workaround of using BeginInvoke worked great. In SL4 however it stopped working so I instead wait half a second before showing the window. This seems to have resolved most problems but now QA is reporting another occurrence of this problem and sure enough it's happening. Any ideas please on how to resolve this issue?

Hi Giancarlo Aguilera,

Thank you for contacting Telerik Support.

You can try calling BeginInvoke in BeginInvoke. I suggest you try this code:

Dispatcher.BeginInvoke(new Action(() =>
{
   Dispatcher.BeginInvoke(() =>
   {
      // your code goes here
   });
}));

Please tell me if this information helps. I will be glad to assist you further.

All the best,
George

Hello,

I am OK now. I am doing what you suggested only that instead of having a nested BeginInvoke I am instead waiting half a second via a timer and then display.

Having said this, these sorts of workarounds seem odd but it is what it is I guess. I certainly understand this is the SL platform we are dealing with here and that probably some pretty complicated stuff is being done by the Telerik windows. Overall I am very satisfied with you SL controls.

Thank you

Hello,

I spoke too soon. This issue is still randomly happening on various machines. I am not able to repro the issue on my dev box. However, QA continues reporting the issue and I just got back from seeing the issue live from a QA analyst's desk.

How do I troubleshoot this? This is SL4. It's a real problem.

Please advise. Thank you

Hello,

It's me again. I REALLY need assistance resolving this problem. Because of the "bizareness" of the issue now management is asking me to consider replacing the RAD windows with something else. That's crazy! Please advise

Hi Giancarlo,

If you could send us a sample project that reproduces the issue and some more information when it happens and on what configurations, this would help a lot to investigate what the problem is.
