Steps to replicate:

Take any standard Syncfusion example which uses DockingManager, e.g. DockingDemo_2008. Put diagram control into the ContentControl.


syncfusion:DockingManager.Header="Docking"
syncfusion:DockingManager.State="Document"
syncfusion:DockingManager.CanDock="False"
syncfusion:DocumentContainer.MDIBounds="60,60,300,300"
syncfusion:DockingManager.CanFloat="False"

*** Any time you drag anything from SymbolPalette onto the diagram, you're getting this exception ****



"Object reference not set to an instance of an object."

Hi Kevin,

Thanks for your interest in Syncfusion products.

The drag and drop exception on hosting diagram into Docking manager has been confirmed as a defect and we have logged a defect report for this. The problem is with the Docking Manager. The drop event of diagram gets overridden by the docking manager drop event and therefore the diagram drop event is never executed. We will provide you the fix for this issue in three weeks.

We appreciate your patience. Do let us know if you have any concerns.

Regards,
Nikhil
