I'm using Prism 4 with Silverlight and I want to use ItemsControl to host multiple views. I really want all the views to be wrapped inside a specified ItemTemplate or be able to specify an ItemStyle so that I can use something like the Expander control in the Silverlight Toolkit . When I try to specify an ItemTemplate an unhandled System.NotSupportedException is thrown at runtime.
ItemsControl.Items must not be a UIElement type when an ItemTemplate is set.

<ItemsControl Regions:RegionManager.RegionName="DetailsRegion">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Red" BorderThickness="1">
<ContentPresenter Content="{Binding}"/>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
