DocumentItemsSource - Same View is created for all ViewModel

Docking/MDI for WPF Forum

The problem is: When binding ViewModels to the DocumentItemsSource of DockSite, only one instance of View is created for all ViewModels.

This behavior is similar to the standard TabControl, but it causes a lot of problems. I want to create a new instance of View for each ViewModel.

What workaround can I apply?

Thanks

    <docking:DockSite Name="dockSite" 
                      DocumentItemsSource="{Binding DocumentItems}" 
                      DocumentItemContainerStyle="{StaticResource DocumentItemStyle}"                       
                      behaviors:DockSiteViewModelBehavior.IsManaged="true">
        <docking:Workspace>
            <docking:TabbedMdiHost />
        </docking:Workspace>
    </docking:DockSite>

Hello,

Unfortunately, there really isn't a good workaround for this. You may be able to bind the DocumentItemsSource to a collection of Views, which you create from your ViewModels. But this really goes against the MVVM pattern.

We have a TODO item marked down to see about adding an option to load all child visuals, even the non-selected. I've added this forum post to that TODO item, so you will be notified when it's completed.
