    Hi, 

    I was trying to create data grid, One column is Dropdownlist.  I want  to pass the dynamic  datasource from the Model. where Model is List<object>  . But the ForeignKey cloumn accepts only SelectList as second parameter. But I want  to make this dynamic i.e model.

    See Below)

    Current Functionality :

      columns.ForeignKey(s => s.FaceId, SelectList)

    I need like   columns.ForeignKey(s => s.FaceId, x => x.FacesList)

    Please suggest me to achieve this  functionality.

    Thanks
    Sunder

    Hello Chris,

    The ForeignKey functionality provide you with the ability to display and edit a foreign key column with a human readable lookup collection instead of working with IDs.
    The only requirement is to pass the collection with the Text/Value pairs at the time you define the Grid - it cannot be dynamically extracted from your model used for the Grid.

    Please notice that your suggestion columns.ForeignKey(s => s.FaceId, x => x.FacesList) would mean that it is possible to have different collection for each record which is not true - same Text/Value pair collection is used for each of the records.

    Kind regards,
