Frank,

Try setting the control properties for the text box to have the PlanFK field as the BindingSourceMember and Policies as the BindingSource. Then set the BindingType to 'None'.

I have done something similar to this in the past with success but I can't say with total certainty that this will work.

I have a Policy Form which allows the user to select a Plan from a gridview, I then display the Plan Code and Description in a text box by concatenating them. The Plan's Primary Key gets stored in Policies.PlanFK. The user must select a Plan as this field cannot be null/empty. How do I tell MM.NET to display the little red exclamation mark icon next to the Plan Code/Description textbox? Right now I get a message that the record cannot be saved and to check the error icons, but none is visible.
