 ## MVVM 
 
-This section explains how to adapt the Syncfusion docking manager to an MVVM application. Since the WPF DockingManager is not an Items Control, it is not possible to have a traditional [ItemsSource](https://docs.microsoft.com/en-us/dotnet/api/system.windows.controls.itemscontrol.itemssource?view=netframework-4.7.2) binding to a collection of objects in the view model. However this can be achieved by creating a wrapper or adapter for the DockingManager.

 ### Docking Adapter
-The adapter is simply a user control that contains DockingManager as its content. The adapter has two properties — ItemsSource and ActiveDocument. Binding a collection of objects to the [ItemsSource](https://docs.microsoft.com/en-us/dotnet/api/system.windows.controls.itemscontrol.itemssource?view=netframework-4.7.2) property triggers a collection change where the adapter creates a corresponding Framework element, example: ContentControl in the DockingManager, setting the underlying data context of the control to the business model.

 ### Application structure

-The view model has a collection of workspaces that is data-bound to the [ItemsSource](https://docs.microsoft.com/en-us/dotnet/api/system.windows.controls.itemscontrol.itemssource?view=netframework-4.7.2) property of the docking adapter. The adapter transforms the particular view model or business object into a corresponding dock element in the DockingManager.

The adapter transforms the particular view model or business object into a corresponding dock element in the DockingManager.
 
 Every dock element in the application is a workspace. There are three kinds of workspaces: the All Documents view, the Properties view, and the Document view. The docking adapter hooks up the “active window changed” event of the docking manager; the view model receives the message whenever the active document is changed.
