Hi Stafan,

That is the latest internal build, however the exception should be fixed. May I ask you to open a support ticket with a sample reproducing the issue so we can see what goes wrong and provide a fix in the shortest terms.

Thank you in advance!

We are planning on using HotFix 02424RadControls_for_WPF_2012_3_1029_DEV_hotfix
Does this pack include the Grouping fix ? is there an internal build you can link me with both included ?

Hello Avishay,

The DragDrop issue has been fixed for the internal build this week which is expected no later than tomorrow. As to the Grouping problem, may I ask you to clarify which issue exactly are you referring to?

Looking forward to hearing from you! 

Kind regards,
