Hi,

I have two subclasses (lets call them A and B), which both inherit from the same baseclass, which has a property named "State" (defined as a State enum). A has B (as in private member variable). Now I would like to databind in some function, for example in the ctor, the "State" property of A to the "State" property of B. Currently I have:

Me.B.DataBindings.Add("State", Me, "State")

Unfortunatly, this throws the error: Object type cannot be converted to target type. Anyone had any luck where you have managed to get this working? If so, could you pls help me out here...

TIA,

Michel van den Berg

B is a derived class of Control?

Indirectly, yes. The baseclass where both classes inherit from, inherits control.

Hmm, sounds odd. It looks the same as if you're binding one textbox' text property to another textbox' text property. I'm not sure if that works (databinding is strange stuff. what looks logical isn't always logical in the databinding universe)

Got it! I had to implement a Public Event [propertyname]Changed As EventHandler

Oh indeed!... the most silly requirement ever but if you forget these databinding falls apart pretty quickly... Ok, I'll stop now before I start a rant..
