I have a custom control that is derived from TabItem, and I want to databind that custom TabItem to a stock TabControl. I would rather avoid creating a new TabControl just for this rare case.

This is what I have and I'm not having any luck getting the correct control to be loaded. In this case I want to use my ClosableTabItem control instead of the stock TabItem control.

<TabControl x:Name="tabCases" IsSynchronizedWithCurrentItem="True" Controls:ClosableTabItem.TabClose="TabClosed" >
        <TabControl.ItemTemplate>
            <DataTemplate DataType="{x:Type Controls:ClosableTabItem}" >
                <TextBlock Text="{Binding Path=Id}" />
            </DataTemplate>
        </TabControl.ItemTemplate>
        <TabControl.ContentTemplate>
            <DataTemplate DataType="{x:Type Entities:Case}">
                <CallLog:CaseReadOnlyDisplay DataContext="{Binding}" />
            </DataTemplate>
        </TabControl.ContentTemplate>
    </TabControl>

EDIT: This is what I ended up with, rather than trying to bind a custom control. The "CloseCommand" im getting from a previous question.
