Hi guys.
I wanted to have a winGrid with only two columns. The first of these columns would be normal and then the second would be a combo.
I fill my WinGrid with a data table as follows:

        DtUnits Dim As New DataTable ("dtUnits")
        dtUnits. Columns.Add ("Data")
        dtUnits. Columns.Add ("Unit")
             While dateB <dateF
                 Dim row As DataRow = dtUnits.NewRow ()
                 row (0) = dateB 'Date mm / dd / yyyy
                 row (1) = "I want COMBO HERE BASED ON another DataTable"
                 dtUnits.Rows.Add (row)
                 dateB = DateAdd (DateInterval.Day, 1, CDate (dateB))
             end While
Me.GRID.DataSource = dtUnits

The combo would serve to enter the unit available on that date, then the combos would be different. I would have units available at a date and unavailable elsewhere.

I inserted the code "e.Layout.Bands (0). Columns (" Unit "). ColumnStyle.DropDownList = Style" at the event InitializeLayout
