When I setup the PopulationDataSourceSettings on a combo box, I am trying to use a FillAll function which return the count of records in the BO after the fill.  I dont care about the return value when filling the combo, but I still want to use the FillAll function to fill it.  However, it's not available in the Method to Execute dropdown unless it's a Sub.  Is there anything that can be done about this or some reason it is like this that I'm not understanding?

I ran this through my test app, and it seems to work.  My assumption is that you want the full count regardless of any subsequent browse dialog results.  This should work...as long as the FillAll() method is run initially.  You may want to consider setting the entire TotalCount property up without the need for the FillAll() method.  In other words keep them separate (although, there is some overlapping code there).
