    I have implemented reordering functionality in RadGridView its works fine. But when I am doing Drag n Drop functionality with ListBox and same grid view at that time its throwing following exception

    Stack Trace:
       at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
       at MS.Internal.XcpImports.Collection_AddValue[T](PresentationFrameworkCollection`1 collection, CValue value)
       at MS.Internal.XcpImports.Collection_AddDependencyObject[T](PresentationFrameworkCollection`1 collection, DependencyObject value)
       at System.Windows.PresentationFrameworkCollection`1.AddDependencyObject(DependencyObject value)
       at System.Windows.Controls.UIElementCollection.AddInternal(UIElement value)
       at System.Windows.Controls.ItemsControl.AddVisualChild(Int32 containerIndex, DependencyObject container, Boolean needPrepareContainer)
       at System.Windows.Controls.ItemsControl.AddContainers()
       at System.Windows.Controls.ItemsControl.RecreateVisualChildren(IntPtr nativeItemsControl)

    Element is already the child of another element.

    Please help me how to resolve this issue?
