WPF VB DataGridCombox DataGridRow

I have gone at this for days and cant find a solution please help.

I have a WPF application I have a DataGridCombobox it has stuff in it (list of Arguments). I can also add free hand typed text into the Combobox like "Test" as shown in the graphic below.

enter image description here

When I add "Test" and click away or add new row I should see "Test" in the Combobox Drop Down List. Instead I see "xFRACASDataController.xFRACASFieldMapper+FieldMappingRow" Where the heck is "Test"

enter image description here

Here is vb.

 Private Sub xDcMappingDataGrid_CellEditEnding(sender As Object, e As DataGridCellEditEndingEventArgs) Handles xDcMappingDataGrid.CellEditEnding
    'get the list from the data grid on mapping tab

    Dim listOfRows As New ObservableCollection(Of FieldMappingRow)
    listOfRows = dataMapViewModel.DgRecords
    'For Each r In xDcMappingDataGrid.Items
    '    'stringList.Add(r)
    '    listOfRows.Add(r)
    'Next

    dataMapViewModel.AddtoArgumentDropDownList(sender.Items.CurrentItem.ToString)
    'dataMapViewModel.AddtoArgumentDropDownList(sender.ArgumentDropDownList(1))
    'dataMapViewModel.AddtoArgumentDropDownList(sender.Items.ToString)
    'dataMapViewModel.AddtoArgumentDropDownList(sender.dataGridRow.Item.ToString)
    'dataMapViewModel.AddtoArgumentDropDownList("TESTING1")
    'dataMapViewModel.AddtoArgumentDropDownList("TESTING2")
    'dataMapViewModel.AddtoArgumentDropDownList("TESTING3")
End Sub

and here is the F# Code

member x.AddtoArgumentDropDownList(argumentText:string) =
          argumentDropDownList.Add(argumentText)
    //Add new Argument in Text to argumentDropDownList
    //Check to see if Text is already in the argumentDropDownList
    //If its there throw it way
    //if Not add it to the argumentDropDownList

    member x.ArgumentDropDownList
        with get() = argumentDropDownList
        and set(t: List<string>) =
            argumentDropDownList.Clear()
            for aField in t do
                argumentDropDownList.Add(aField)
            x.TriggerPropertyChanged("ArgumentDropDownList")

    member x.Arg1
        //with get() = argumentDropDownList
        with set(t: string) =
            //argumentDropDownList.Clear()
            //for aField in t do
            argumentDropDownList.Add(t)
            x.TriggerPropertyChanged("ArgumentDropDownList")

IF I hand Jam "TESTING1" its in the Combobox Drop down. I have added a watch to Items.CurrentItem. shown below. "Test" is in Arg1

enter image description here

But not in the physical list itself. Any help is greatly Helpful.

Note that you are not very likely to get a good answer to your question, because it is very specific and there is no way for us to run your code.

However, xFRACASDataController.xFRACASFieldMapper+FieldMappingRow is a kind of string that you'd get when you run ToString on an object that does not implement any clever formatting as text - it seems to be the name of a class, in this case FieldMappingRow (which is a nested class in xFRACASFieldMapper).

In the code you posted, you are calling ToString in the VB code on line:

dataMapViewModel.AddtoArgumentDropDownList(sender.Items.CurrentItem.ToString)

What is the type of sender.Items.CurrentItem? Is this perhaps an instance of FieldMappingRow? If so, then I think you need to extract the text from the object in some other way than by calling ToString.
