I save the docking manager layout with
using (var fs = new FileStream(@"Data\XDMLayout.xml", FileMode.Create, FileAccess.Write)) { dockingManager.SaveLayout(fs); }
and load with
using (var fs = new FileStream(@"Data\XDMLayout.xml", FileMode.Open, FileAccess.Read)) { dockingManager.LoadLayout(fs); }
and everything goes well, until I change one of the panes to floating. After saving and attempting to load I have the exception below. Can Infragistics please help?
System.ArgumentException was unhandled

Pankaj,
For us to look into this we need a sample that we can run that reproduces the issue. Rob is working with you through case CAS-145323-P1K7Q2 for this so please provide him with more details through the case.
Let me know if you have any questions with this matter.
Hi Did anyone found the solution to this issue ?
We think the Crash we are observing in our code matches with this case. Please Reply if anyone found any solution
We are having a similar problem. Our users save workspaces and then can move things around and reload the saved workspace. When they move a pane to floating and attempt to load a basic layout that brings the pane back to the dock manager the error "Hwnd of 0 is not valid" occurs. We are using a SaveLayout and LoadLayout call to do this and the problem does not happen every time but most. Any suggestions would be great!
Thanks Andrew. How can we do that in a way it is not posted it in public domain? Does Infragistics have some sort of Issue Tracker where we can follow up on this? Of course Ill come back and post the solution on this forum once its is resolved.
OnSourceInitialized is invoked when the window has been created so if the window handle is 0 then the window was destroyed/closed while the window was being opened but before the OnSourceInitialized was invoked. I think we'll need a project that demonstrates the issue so we can see what caused that.
