Dockpanel Test

Hi there !

I tried to use the DockPanel controlaccording to the instructions at your web site .
But the only time I get the below error . I can config control on Modeleditor
but everytime i\'m trying to show it error appears.

There is no data sessions involved, so i\'m propably missing some assemblies?
