I am able to register the usercontrol(view) as the toolwindow using the prism integration with docking .

As i run the application usercontrol will be display as the toolwindow in my main application and i am handling the windowdrgaging event for that docksiteof the usercontrol  but not able to get the usercontrol from that toolwindow.

ForExample 

void dockSite_WindowDragging(object sender, RoutedEventArgse)

{

DockSite dockSite = (sender asDockSite);

List<ToolWindow> twlist = dockSite.ToolWindows.ToList();

foreach (ToolWindow tw intwlist)

{

if (tw.Name == "abc")

{

----------How to get the view of usercontrol from this toolwindow. like tw.GetView();

DockSite.SetControlSizeForState(tw.ParentContainer, newSize(230, 165), DockingWindowState.Docked);

}

}
