    Hi Telerik,

    we are creating a RadWindow using below code and we got a RadSchedulerView inside the usercontrol which is the content of the RadWindow and This is common method in our application.

    var radWindow = new RadWindow
                                            VerticalContentAlignment = VerticalAlignment.Stretch,
                                            HorizontalContentAlignment = HorizontalAlignment.Center,
                                            Header = menuCaption,
                                            Tag = windowId,
                                            Content = content,
                                            Width = width,
                                            Height = height,
                                            IsRestricted = true,
                                            WindowStartupLocation =
                                            RestrictedAreaMargin =
                                            new Thickness(RestrictedAreaLeft, RestrictedAreaTop,
                                                              RestrictedAreaRight, RestrictedAreaBottom)

    Adding the DragDrop behavior to the control.

                    RadDragAndDropManager.SetAllowDrag((UserControl)content, true);
                    RadDragAndDropManager.AddDragQueryHandler((UserControl)content, OnDragQuery);
                    RadDragAndDropManager.AddDragInfoHandler((UserControl)content, OnDragInfo);

    On the RadSchesuler when I start drag,CanStartDrag event fires and CanDrop event never fires.
    I think one of the above methods are overriding the CanDrop method on CustomDragDropBehavior class.

    Any suggestions to make DragDrop work for RadSchedulerView inside RadWindow.

    public class CustomDragDropBehavior : Telerik.Windows.Controls.ScheduleViewDragDropBehavior 
            public override bool CanDrop(DragDropState state)
                return true;

            public override bool CanStartDrag(DragDropState state)

                return true;

            public override void Drop(DragDropState state)

    Hi Kotte,

    Actually this is expected - there are some changes in the DragDropBehavior of the ScheduleView in the latest version, that's why you cannot use it together with the RadDragAndDropManager.

    Please send us more information about your exact scenario and we'll try to find a suitable solution. Thanks
