RegisterMdiChildTypes throw ApplicationException

[Henry Nguyen]

I upgraded my application from 3.2 to 7.1, When the main form call RegisterMdiChildTypes to register a child form, the application crashed with stack trace:


Error Message: A BarItem not part of a BarManager's Items list is encountered.
Exception Type: System.ApplicationException
at Syncfusion.Windows.Forms.Tools.XPMenus.BarItemID.FromBarItem(BarItem item)
at Syncfusion.Windows.Forms.Tools.XPMenus.MergedBar.MergeBars(Bar[] bars)
at Syncfusion.Windows.Forms.Tools.XPMenus.MergedBar..ctor(Bar[] barsToMerge, BarManager manager)
at Syncfusion.Windows.Forms.Tools.XPMenus.MainFrameBarManager.InitMergedBars()
at Syncfusion.Windows.Forms.Tools.XPMenus.MainFrameBarManager.RegisterMdiChildTypes(Type[] formTypes, Form[] forms)
at Syncfusion.Windows.Forms.Tools.XPMenus.MainFrameBarManager.RegisterMdiChildTypes(Type[] formTypes)

I figured out because in the main form, I remove references to some bar items (mainFrameBarManager.RemoveReferencesToBarItem) is the cause of the problem. My question is what I need to do in the child form or the main form to fix the problem, I cannot find what bar items in the child form that caused the merged problem, any hint to find them?

Hi Jaya,

Thanks for the response, I was able to fix the problem. When We use RemoveReferencesToBarItem method on both ParentBarItem and BarItem, we get the exception. This exception is not thrown in 3.2, but in 7.1.
