I'm getting the following error and I'm not having much luck figuring out what's going wrong.
Unable to cast object of type <my Form> to type 'Infragistics.Win.UltraWinDock.FloatingWindowContainer'.
I have several forms that I open as MDI Children that were working fine yesterday, I know I must have done something but I don't know what...now one of my forms will not open in VS's designer or at run-time.
Can anyone tell me what might be causing this?
If this is happening when you open the form, there could be a problem with the dock manager's serialization logic and I would recommend submitting the issue to the support group: http://es.infragistics.com/gethelp. Also, if there is a stack trace associated with the exception, I might be able to offer more help.
