Hello-

I have an interesting scenario which I would appreciate some guidance on.  I have a xamdatagrid bound to a datatable with dynamically created fields (so no XAML code will work that I am aware of.)  I would like to have a single cell of each field use a comboboxeditor to select from a range of values.  I have it partially working.  If you look at the picture attached the fields that have numeric names are the dynamically generated ones.  I have only been able to set the whole field to the combobox editor so far, as seen in the picture.  The only one that should be a combobox is in the rounding record, the others should be decimal numbers, which work correctly otherwise.  The rounding record contains the correct values, so I am that far already, but the combobox is displayed at zero width, so that is something that needs fixed as well.

Below the picture is my VB code in the InitializeRecord event.  There are a few commented-out lines where I was trying to access the cellvaluepresenter, but I don't think it exists yet in the InitializeRecord event, so that didn't work.  I also attached the XAML for the combobox style I am trying to set it to.  The datatable contains a decimal number, which corresponds to a string name (example: .10 = "1/10 Hour")

 Private Sub grdOperations_InitializeRecord(sender As Object, e As Infragistics.Windows.DataPresenter.Events.InitializeRecordEventArgs) Handles grdOperations.InitializeRecord

        If DirectCast(DirectCast(e.Record, DataRecord).DataItem, DataRowView).Item("Name") = "Rounding" Then

            For Each f As Field In e.Record.FieldLayout.Fields

                Dim i As Integer = Nothing

                If Integer.TryParse(f.Name, i) = True Then

                    'Dim cvp As CellValuePresenter = CellValuePresenter.FromRecordAndField(DirectCast(e.Record, DataRecord), f)

                    'If cvp Is Nothing Then Exit Sub

                    'cvp.Style = CType(Me.Resources("RoundingStyle"), Style)

                    f.Settings.EditAsType = GetType(RoundingIncrement)

                    f.Settings.EditorStyle = CType(Me.Resources("RoundingStyle"), Style)

                End If

            Next

        End If

    End Sub

<Style x:Key="RoundingStyle" TargetType="{x:Type igEditors:XamComboEditor}">
