KeyNotFoundException after floating the only contentpane in XamDockManager
posted

Hello,

we have a problem with the dockmanager. After floating the last tab inside the dockmanager, and adding a new contentpane via prism, which is docked by default, we get a



KeyNotFoundException


The region manager does not contain the workspace region.

After googling for a while, I found that the TabGroupPane gets recycled. Is that the case? If yes, how to prevent this (except adding a dummy tab control)?

Thanks in advance

Christian

    Hello Christian,

     

    Thank you for your post. I have been looking into it and I believe that the best approach is to add dummy tab control, but if I think of another possible solution for you I will let you know.
