Hey CAB Afficionados!

Got another research item. 
 
How do I utilize the ListConverters in a view control that has the presenter injected (syntax) and does not inherit from ControlViewPresenter (inheritance)?
 
The presenter of my new control view with a toolbar is not inheriting from ControlViewPresenter (perhaps, it should, somehow), so it is not getting the SetBindingListConverter method.  It inherits from AppViewPresenter.  To see what I mean, try adding a ListConverter to a GridViewControl.  It has the same basic inheritance as my new view.

The presenter for any view showing loose controls bound using a DevForce ControlBindingManager should inherit from ControlViewPresenter.

Ok.  How do I get the control view (based on the exact same inheritance schema of the grid view) to inherit from the ControlViewPresenter?

Obviously, I will go to work on this myself.  If I discover the proper path, I will relate it here.

Instead of my ControlViewWithToolbarPresenterBase inheriting from AppViewPresenter, I changed it to inherit from ControlViewPresenter (which has AppViewPresenter in its own linkage).  That created an avalanche of changes to my classes in order to re-accomodate the inheritance.  It would not be prudent to list them all here...let's just say, there were a lot of things changed.
 
Now, to test these changes against my app...then to add ListConverters. 
 
Stand by.

The changes flowed through nicely.  The views in my app worked exactly the same as before I made the switch to the ControlViewPresenter inheritance.
 
Ok.  Now, back to my first question.
 
How do I utilize the ListConverters in a view control that has the presenter injected?  Where do I place the code?
 
Example:
 
EntityPropertyDescriptors.AddressMasterPropertyDescriptor descriptors = EntityPropertyDescriptors.AddressMaster;
SetBindingListConverter(descriptors.CarrierMaster, ListConverterNames.CarrierList);
SetBindingListConverter(descriptors.Carrier, ListConverterNames.CarrierIDList);
 
Thanks for any insight here,
Bill

Is this just a workaround?
 
I created a new presenter for my AddressView rather than allowing straight injection.  Within that presenter I placed the code I needed for the ListConverters.  That actually works.  However, is it the best, CAB way of doing this?

Yes, I think that's the right way to do it.  See also my post on the topic "Binding Combo Boxes".

Thanks, Bill!  Adding the presenter seemed to make the most sense.
