Replacing ItemsControl ContentPresenter entirely with control being rendered

i'm using an ItemsControl to generate a list of controls based on my model. When looking at the visual tree, i noticed that each of the rendered control is wrapped in a ContentPresenter. The controls that are added are a 3rd party control and are designed to display a splitter between each control if they are siblings..this allows a user to size each control. For example the following will show a splitter between each of the controls at run time.

<StackPanel>
<3rdPartyControl />
<3rdPartyControl />
<3rdPartyControl />
</StackPanel>

When using an ItemsControl, each of the 3rdPartyControl are wrapped in a ContentPresenter, and thus no splitter is shown. I have tried various ways to try and solve this problem but unable to get this to work unless i write code behind to add each control rather than rely on Xaml. Does anyone know of a way to replace the contentpresenter completely (in my case with 3rdpartyControl)?

Thanks

In order to replace the ContentPresenter you could derive from ItemsControl and override the GetContainerForItemOverride method to create a specialized container control.

ListBox for example overrides this method to create a ListBoxItem as container for a new item object.

That's true, every element that you add to ItemsControl is wrapped with ContentPresenter, you can find more details about it in the greate series of articles from dr.wpf ItemsControl a-z

One way I would suggest to try is to change ItemsControl to ListBox and make ListBox act like ItemsControl. In this case you can re-style/re-template ListBoxItem and replace ContentPresenter with your control. You would also need to stop selection support. Here is ListBox style that you need to change.
