It crashes when I do this:
- I have a class Person, with properties Name:string, Age:int and
Children:PersonCollection. PersonCollection is based on CollectionBase
and adds
int Add(Person);
Person this[int] { get; }
to the class.
- I create an instance of this class, and display it in a
System.Windows.Forms.PropertyGrid control.
- Up until now, everything is just fine, I can change properties, and
the framework-provided typeconverter and UI lets me add and remove
Children and set their properties.
- When I try to manipulate the children's children, it crashes. An
exception is thrown when I push the ... button to open the collection
UI.
The exception is 'System.StackOverflowException'
