Hi all

I was wondering how CanEditObject() and CanWriteProperty() can have different behaviors based upon some instance criteria (for example... CanWriteProperty = !this.ReadOnly)? It is possible to check that in property setter and throw exception there, but it would be nice if ReadWriteAuthorization class could check that also and make GUI control enabled/disabled.

Any workarounds?

The CanReadProperty() and CanWriteProperty() methods can be overridden, allowing you to customize behavior if needed.

Tnx Rocky for the reply.

One more question. Should I place also attribute like this?

[EditorBrowsable(EditorBrowsableState.Advanced)]
public override bool CanWriteProperty(string propertyName)

Probably. I guess it depends on whether you want the method to appear in most cases. Honestly, in C#, this attribute is almost useless because most people have VS set to show advanced members... But it is a best practice, because VB has a more sophisticated way of showing advanced members in intellisense, and you never know what the C# team might do in the future as well.
