Hi All!

I want use PropertyGrid control in window my AutoCAD plagin's for browse drawing database entities. But it is big problem in AutoCAD:
I have always fatal error for some AutoCAD entities, when these used as ObjectSource property for PropertyGrid.

For example (fatal source): Database, BlockTable, BlockTableRecord, Circle and many other!

I don't really see anything wrong. I would try committing your transactions instead of letting them abort. I would also try locking each document as you iterate though.

I was attempt set property of PropertyGrid in try/catch - exceptions not occur. But after exit from try-block, I have fatal errors. Now I use binding in xaml-code. But problem still occur.
My theme dub there.

Ok, as Tony mentioned, if the treeview tries to access the property of a DBObject while it's not opened for read,  Kaboom.
