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.
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"
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
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
.
