I need to create a control which has a single permanent tab (“home”), and all of the other tabs are scrollable.

Right now I am trying to achieve this result by subclassing the TabControl, adding an extra button (which looks like a tab) to the overridden template, and setting the SelectedIndex to -1 whenever the button is clicked. When SelectedIndex is -1, a trigger causes the TabControl’s ContentControl to be bound to a special “Home” tab’s content. Basically, I am faking the behavior of a real tab and overriding the ability to deselect all tabs in doing so.

This seems to work, except for two problems:

  1. Select example tab #3, then select home. THEN, try to select tab #3 again. Tab #3 doesn’t respond.
  2. Select tab #3, then select home. THEN, try to use the menu which happens to be in the same window. When I go to use the menu, #3 pops up as the selected tab again.

I’ve tried to listen to all kinds of events associated with the TabControl at this point, but none of them seem to give me something I can work with to get around these behaviors.

Is there something out there that will allow me to override the default SelectedIndex behavior? Should I be doing this another way? Ideally, I would like some way to take in a collection of tabs that allows me split up the tabs visually without losing the basic functionality of a TabControl.

    I was able to implement this by writing my own custom tab panel, as AresAvatar suggested. However, the panel needed to extend from the ConceptualPanel implementation from http://www.codeproject.com/KB/WPF/ConceptualChildren.aspx. The problem is that the panel needs to have IsItemsHost="true" in the TabControl template to preserve the tabs’ selection behavior. Unfortunately, once a normal panel is an items host, it’s Children can’t be changed from inside it’s own class code. So, I couldn’t add the scroll buttons that I needed. I was able to get around that problem with the ConceptualPanel by adding everything (tabs + scroll buttons) via AddVisualChild.

    There might be a better way to do this, but this worked for me.
