HwndHost DocumentWindow not rendering when docked

Hi Bobby,

HwndHost controls should work fine with our product, and I know we have many customers who use them.  What kind of root Window are you using?  Is it a pure Window or something else?  Also, have you applied one of our WindowChromes on it?  Try making sure you use a pure Window without any chrome and see if that gets it going.  I believe our WindowChrome will allow interop content fine, but it's a good place to start in case that is what's causing the problem  Let us know what you find..

If you can't figure it out, could you make a new simple sample project that shows this issue you're having, and email that to our support address?  Please reference this thread and rename the .zip file extension so it doesn't get spam blocked.

It is a pure win32 window, no custom chrome or anything. What i'm doing is launching an exe, making the process a childwindow through C# interop calls and embedding the resulting hwnd into a hwndhost. This HwndHost is then set as the content for a contentcontrol inside my usercontrol.

As I mentioned, this does work once I raft the toolwindow but not if the tool window is docked. I will make a tiny demo project and send that to you tonight.

Sorry, I misunderstood your question. Yes, my root window did have a custom chrome applied to it, that was the problem. Using your window chrome fixed the issue! Thanks!
