    I am working in VB.NET and I am using the FlexGrid control. I need to add a column with a databound dropdown list. It needs to have a value (integer) and a display value (string) which it will get from the database. The user needs to be able to select a value when adding/editing a row and of course, the control needs to display the correct display value (depending on the value of the field) when rows are loaded. I can't seem to find any instructions on how to accomplish this.

    I tried this which sort of works:

    Dim ComboSegment As New ComboBox
    ComboSegment.DataSource = SegmentTable
    ComboSegment.DisplayMember = "Name"
    ComboSegment.ValueMember = "SegmentID"
    Dim col3 As C1.Win.C1FlexGrid.Column
    col3 = C1FlexGrid1.Cols.Add()
    col3.Name = "SegmentID"
    col3.Caption = "Segment"
    col3.Editor = ComboSegment

    The problem is that the FlexGrid column displays the key value (valuemember) unless the cell is in edit more at which time it displays the displaymember of the combo box. That of course does not work very well for users.

    Figured out how to do it with a DataMap. Is that the best way to do this?
