A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E2410.

You can define a Window, Page or UserControl in external XAML files and then, with DXDocking, load their contents into DocumentPanel objects.


This example demonstrates how to load an external Window and UserControl into DocumentPanels.


In the example three approaches are demonstrated:


1) The contents of MyWindow.xaml is loaded into a DocumentPanel at design time (in XAML) via the DocumentPanel.Content property. The Content property accepts a Uri object, which must refer to a XAML file defining a Window, Page or UserControl.


<dxdo:DocumentPanel x:Name="docPanel2" Caption="Panel 2" Content="{dxdo:RelativeUri UriString=CustomWindows\\MyWindow.xaml}"/>


2) The DocumentPanel.Content property is set with a Uri object at runtime:


docPanel1.Content = new Uri(@"CustomWindows\MyWindow1.xaml", UriKind.Relative);

 


3) The DockLayoutManager.DockController.AddDocumentPanel method creates a new DocumentPanel object and loads the contents of an external XAML file into the created panel.


panel1 = dockLayoutManager1.DockController.AddDocumentPanel(documentGroup1,

new Uri(@"CustomWindows\UserControl1.xaml", UriKind.Relative));

panel1.Caption = "Document " + (ctr++).ToString();



In the example, the XAML file defines a UserControl object. The loaded UserControl is accessed via the DocumentPanel's Control property and then a method on the UserControl is invoked.


//...

(panel1.Control as UserControl1).SetDataContext(imageInfo);



You can see this in action by clicking the "Set DataContext for UserControl" button in the example.
