Hello Horst,
Thank you for writing.
I tested the examples in
the forum thread and I have found a problem with the last demo
RadDockQueries-2.zip when using our latest control version (Q3 2012 SP1).
This issue is caused by some major changes in the internal element structure of our control. I have tested with a previous version (Q2 2012 SP1) and everything is working properly there, so if this is an important feature for you, you can temporary use Q2 2012 SP1.
We will address this feature in our next service pack after Q1 2013. You can use
the following link to track the issue status and get notified when its done.
I updated also your
Telerik Points for bringing this issue to our attention.
I hope that you find this information useful.
Greetings,
Plamen
the Telerik team
