Exception When Dragging object from a floating window

Dec 8, 2014 at 8:00 AM
We have integrated the Xceed DockPanel in one of our project.
Our project is divided in three main components

-1 Component for the configuration (LayoutDocument)
-2 A componet to store library elements (LayoutAnchorablePane)
-3 A component to automatically detect elements on a network (LayoutAnchorablePane).

All these components are hosted inside a dock DockPanel communication between components
-1- and components -2- and -3- is achieve using OLE Drag and Drop standard mechanism.
OLE exchanges between elements -1 and -2 and elements -1 and -3-working properly as long as -elements 2 and -3 are not floating windows. When property of elements -2- or -3- is set to floating we get Exception: (Additional information: Invalid tymed (Exception from HRESULT: 0x80040069 (DV_E_TYMED)) when dragging object. Any idea on this problem?
