Hello, I just installed the demo. It seems to work fine when I click on an item on the tree list but when I click on another item on the tree list, it crashes. It always crashes when I select my second item but the first item loads fine.

Here's a screenshot: http://img291.imageshack.us/img291/7963/crashwi6.jpg

Hi Miguel,

First of all, I apologize for the late reply.

Did you mean that the QSF crashes upon clicking on an item? Can you elaborate a bit more on what you did before the problem appeared? Step-by-step details will be of great help for us to try to reproduce the problem locally.

Sincerely yours,
Nick

When I load the application, I am able to click on a single item and it will load correctly. The moment I select another item from the list, that's when the crash occurs. It happens 100% of the time.

Hello Miguel,

Sorry for the caused inconvenience. After performing some tests at our side we did not reproduce this problem. I would suggest that delete your browser's cache(if you run the sample as a .xbap application), and then download again the installation and run it again. We really have no clues what might be causing the problem as everything is running as expected at our side.

Let us know how this goes.

Regards,

the Telerik team

Hello Tor,

We are sorry to hear that you experience any problems with our controls.

We tried to reproduce the problem, but to no avail. Could you please provide us with more details on how to reproduce the issue? Does the error appear  when you click on a particular example? If so, could you tell us which is the example?

This will help us to understand the problem better and provide you with more specific instructions. Also I suggest you install the examples locally and let us know how this goes.

Hi,

I'm experiencing the same thing. The xbap seems to load just fine, but when I try to navigate to any of the links I get the same security exception. FYI.


Kind Regards,

Arne Wauters

I had the same problem, an issue with the UIPermission (I'm running on Windows 7).

However, when I ran IE in Administrator mode (bad idea, generally), it worked fine.

Can the fact that the user is not an administrator cause a problem?

Hello, I meet the same issue as well.

yonadav, I'm not sure if this is a UAC issue in Vista and Windows 7.
I run on Vista with UAC disabled but see the same issue.

My guess is that the Demo XBAP application requires full trust to run.

Telerik team,
Do you think you could test this via internet.

Thanks,
yagimay
