scenario:

• Table PropertyGroups:
• ID
• Name
• Comment
• Table Properties
• ID
• Name
• PropertyGroups_ID
• Comment

I have Maintanance form to add and modify the propertygroups allready.

Now on the Maintance form for the Properties, i'd have:

• Textfield: Name
• Combobox: PropertyGroup
• Textfield: Comment

What i need is for the Combobox to allow selection of anyone of the Property-Groups from the PropertyGroups Table/BO, and saving the selected PK/ID from that Property Group into to Propertie-Table/BO PropertyGroups_ID column.

what is the proposed way to achieve that ?

thanks.

thanks for the screenshot. so i set the list population like on the screenshot in my case using PropertyGroupsBO and then i set the BusinessObject-Property of the combobox to Properties, i guess ?

Yes, and you use bind the combo to the FK field in the PropertiesBO.
