tabbed MDI WindowsFormsHost behavior

Docking/MDI for WPF Forum

I am using a tabbed MDI and one of the documents uses a WindowsFormsHost to enclose mapping control (ESRI).  I was having an issue wit hthe recreation of the mapcontrol when navigating away from the map document tab, and then back.  Microsoft states that the WFH will recreate child controls when the page uses Navigate().  Is this the case with the tabbedMDI?

Hi Robert,

Our tabbed MDI works similarly to a standard WPF TabControl where the selected tab's content is presented in the client area of the tab control.  When that tab is not selected, it will remove the content from the visual tree.  We don't do anything fancy for WindowsFormsHost handling though in that sort of code, so what you see is perhaps just how WPF handles swapping in and out of WindowsFormsHost controls.
