Question

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.
