DocTabStrip Overflow

[MikeB]

Hello,

Does anyone know if there is a property that can be checked if a Tabbed Document is visible on the TabStrip or is in the list of overflow tabs?

Or

What event is triggered when a Tabbed Document is selected from the list of Overflowed Tabs, besides the SelectedTabChanging/Changed?

I need a way to distinguish when a DockWindow is selected by clicking on the Tab versus selected from the overflow list.

Thanks,

Mike

Hello Mike,

I've written a small exmaple for you on how to distinguish between selecting a tab via clicking on it as opposed to using the context menu in the overflow button to select the tab.

Hope this helps.
