I have 3 or more cascaded objects - for example: Country (CountryID and CountryName columns), Town (TownID, TownName and CountryID columns) and Street (StreetID, StreetName and TownID columns) - just for illustration, I'm not using objects for towns and streets . There is 1:N relationship between Country and Town (through CountryID column) and 1:N relationship between Town and Street (through TownID column).

Now I want to use StrataFrame standard windows form for adding and editing of Street object. It works fine with Street object as a primary object. I can even use combo for selecting town. But I would like to use another combo that would be used for selecting country and based on selected country the combo with towns filtered - however I do not know how to do it since there is no direct relationship between Country and Street objects. Is there any possibility to make it?

Thanks a lot

thank You for Your responses! Based on Your posts I have manage it.

In fact the problem was that I tried to automate the country combo behavior by setting is as bound control with object relationships. As I have written before I'm very new to StrataFrame and I like it because a lot of things are automated. So I tried to get it as automated as possible to take advantage of StrataFrame.

Now I have unbound combo with countries and I handle events manually.

Thank You ones more :-)
