We have run into a problem trying to load the state of docking controls using Syncfusion 4.2.0.37. Our application has an OverviewControl that is docked to the mainform in the designer and is initially hidden on load. An Invalid Cast assertion is raised in the method DocToFormController in DockingMgr.cs during the call to LoadDockState. This same code worked correctly in 4.1.0.50.
Attached is a modified version of the DiagramBuilder sample that shows this problem. To reproduce the problem, do the following:
1. Open the DiagramBuilder
2. Close the DiagramBuilder (to save the docking state)
3. Open the DiagramBuilder again.
You don''t even need to open the OverviewControl to see the problem.
We are using VS 2005 with .Net 2.0. We would appreciate any help you can provide.
Thanks in advance for your help.
