TabControl ScrollViewer_MouseWheel unhandled exception

[Manuel]

Hi guys, 
my application recently logged the following unhandled exception.
It happened just once and I'm unable to reproduce it, but looking at the stacktrace it seems an invalid cast on the RadTabControl.ScrollViewer_MouseWheel.

I never subscribe to that event so I'm assuming it's something related to RadTabControl internal implementation...
Can you have a look at it?

Thanks

Manuel

Hello Manuel,

Thank you for reporting this issue. We have isolated the scenario and the root cause is the embeded MouseWheel scrolling functionality of the RadTabControl. We have logged that issue in our system and you can track its progress in our feedback portal. I have also updated your Telerik points as a small appreciation for your cooperation.

Please excuse us for any inconvenience caused.

Kind regards,

Great, just one more question: "status Approved" means that the fix has been planned for the next release?

Hello Manuel,

Status "Approved" means that we have verified that an issue is reproducible in the controls and it need to be fixed. Which items to be fixed for the next release are calculated by other criteria such as impact over the control, votes, scenario .. e.t. However due to the nature of this issue (exception) it has a high priority and we have scheduled its fix for our next official release.

Kind regards,
Kiril Vandov
