How to hide the title of a tab of a LayoutPanel / LayoutDocument?

Question

Good morning everyone!

I'm using the AvalonDock on a project, and I ended having a question:

In some pages developed in my project, I have custom titles which use a standard textBlock. And in some pages, this specifically, I have a LayoutAnchorable anchored on the left side of the page, and a LayoutDocument anchored on the right side.

For LayoutDocument, the title is empty, because I already have a title on this page. This causes the TabItem (Title) of this LayoutDocument Tab still appears with empty value. As I would like to maintain my titles on all pages, I wonder if there is how I hide or remove this blank tabItem, which is the title. One of my attempts was modify the margin of the page, I got her stay up page. But this LayoutDocument TabItem is readjusted downward, keeping it visible.

I know this is not a problem AvalonDock, is a different behavior of the original design. The tab Title of the document was not meant to be hidden, but I think it would be interesting for those who want to have their own title pages. Best Regards.

Gustavo.

There was a property to do just what you want in AvalonDock versions prior to 2.0. It was DocumentPane.ShowHeader

In 2.0, you either have to rewrite the entire DockingManager Style, or modify AvalonDock.

I created an issue for this in the issue tracker, and attached a patch that you can download to have to feature again.

This patch was made against a prior version, and might need some tweaking if you apply it to current version. Also, it does not handle new themes that were released since then.

In the current version, you can add this code to hide documents' titles:

<xcad:DockingManager.DocumentTitleTemplate>
    <DataTemplate>
        <Grid/>
    </DataTemplate>
</xcad:DockingManager.DocumentTitleTemplate>
