DockingManager "Index was out of range..." exception

[Dimitar Milov]

Hi,
I've upgrade my syncfusion from 3.3.0.0 to 4.1.0.50 and in all UserControls that i have dockingmanager arise the following eception:

"Insertion index was out of range. Must be non-negative and less than or equal to size.\rParameter name: index"

CallStack :

at System.Collections.ArrayList.Insert(Int32 index, Object value)
at Syncfusion.Windows.Forms.Tools.SizingController.InsertChild(DockControllerBase dc, Int32 index, DockingStyle db)
at Syncfusion.Windows.Forms.Tools.SizingController.AddChild(DockControllerBase dcinternal, DockingStyle db)
at Syncfusion.Windows.Forms.Tools.DockingManager.DockToFormController(DockStateControllerBase ctrl)
at Syncfusion.Windows.Forms.Tools.MainFormController.InvokeDocking(DockControllerBase dc)
at Syncfusion.Windows.Forms.Tools.DockingManager.InternalDockControl(Control ctrl, DockControllerBase dcbparent, DockingStyle dockstyle, Int32 nsize)
at Syncfusion.Windows.Forms.Tools.DockingManager.DockControl(Control ctrl, Control parent, DockingStyle dockstyle, Int32 nsize, Boolean tabGroup)
at Syncfusion.Windows.Forms.Tools.DockingManager.DockControl(Control ctrl, Control parent, DockingStyle dockstyle, Int32 nsize)

It happens within constructor of the UserControl when I call DockingManager.DockControl. With the old Syncfusion version (3.3.0.0) everything works fine.

Do you have some idea what is the reasen?

Hi Dimitar,

I am afraid that I am not able to reproduce the issue with the attached sample in Essential Studio version 4.1.0.50.

Please try running the above sample. If still the issue exists, kindly try reproducing it with this sample and send it back to me so that it would help me to find out the cause of the issue.

Thanks for your interest in Syncfusion products.

Best Regards,

Unfortunately, I can't reproduce this exception in your example, but reasen is DockStreamLayout, when I delete the serialized base64 value from the .resx file my application works fine. When I made some changes in the designer and DockStreamLayout is recreated the exception occurs.
