Question

In Windows Forms the default behaviour of a TabControl is to have the tabs spill out to a scrollable area if they consume too much space (MultiLine = false).

What is the best approach to achieving this behavior in WPF?

UPDATE

I was trying to find a solution using TabControl.ItemsPanel but it seems anything I put in there gets completely ignored, so for this reason I’ve gone the hard way and started with TabControl.Template which is mind boggling that we have to do it this way if it turns out to be the correct approach.

Extremely far from being complete, my starting solution to the problem is as follows.

<TabControl>
  <TabControl.Template>
    <ControlTemplate TargetType="{x:Type TabControl}">
      <DockPanel>
        <ScrollViewer DockPanel.Dock="Top"
                      HorizontalScrollBarVisibility="Auto"
                      VerticalScrollBarVisibility="Disabled">
          <StackPanel Orientation="Horizontal" IsItemsHost="True" />
        </ScrollViewer>
        <ContentPresenter ContentSource="SelectedContent" />
      </DockPanel>
    </ControlTemplate>
  </TabControl.Template>
  <TabItem Header="One">First</TabItem>
  <TabItem Header="Two">Second</TabItem>
  <TabItem Header="Three">Third</TabItem>
  <TabItem Header="Four">Fourth</TabItem>
  <TabItem Header="Five">Fifth</TabItem>
</TabControl>

In working to make a TabControl where the tabs are stacked vertically along the left, I found this solution for you:
