Field value not shown in form

Hello! My task is to copy one field that contains string value from the details tab page to grid of the same form. I drag&dropped this field from a datasource to grid, but it is shown empty. There is a value contained in this field in debugger.
What else should I check?

Does the grid shows records of ConsigneeAddress data source, or is ConsigneeAddress joined to the data source used by the grid?

yes, it’s joined as far as i know
i attach datasource’s and grid’s properties

I solved the problem by changing LinkType property of Datasource from Active to OuterJoin.
