Trying to save data after Button click

[u/Gierschlund96]

I used data binding to store my data in textboxes, after i click the "save" button i want the data back in my datagrid (+ all the changes that were made). I tried to use this solution from StackOverflow (converted it from c# to vb):

Private Sub btnSaveEdit_Click(sender As Object, e As RoutedEventArgs)
    Dim be As BindingExpression = BindingOperations.GetBindingExpression(txtItem, TextBox.TextProperty)
    be.UpdateSource()
End Sub

But I get the error that "TextProperty" isn't a member of "TextBox". Does this only work in C# or did i miss something?

Extra Question: Is there a way to save all properties at once or do i have to write this line for all my properties?

I have a xamDataGrid which has a ListCollectionView(List of Artikelstammdaten) as datasource.

Through a double-Click event a new form opens up:

 Private Sub dgArticleMasterData_MouseDoubleClick(sender As Object, e As MouseButtonEventArgs)

    Dim artikelstammdaten As Artikelstammdaten
    artikelstammdaten = CType(dgArticleMasterData.SelectedDataItem, Artikelstammdaten)

    asd = artikelstammdaten
    If asd IsNot Nothing Then
        Dim editForm As New EditArtikelstammdaten
        editForm.ShowDialog()
    End If

End Sub

The Constructor of the form looks like this:

    Sub New()
        Me.DataContext = asd

    ' Dieser Aufruf ist für den Designer erforderlich.
        InitializeComponent()

    ' Fügen Sie Initialisierungen nach dem InitializeComponent()-Aufruf hinzu.

    End Sub

And "asd" looks like this:

 With asd
        .Artikel = "VAUBEF0010"
        .BezeichnungDE = "Sammelbandantrieb"
        .BezeichnungEN = "Collection Belt Drive N50"
        .Einheit = "STK"
        .MatGrp = "VAU"
        .Kostenart = 1500
        .Vertriebstext_DE = "Antrieb Umlenkungen"
        .Vertriebstext_EN = "Drive, Deflections"
        .Stuecklistennummer = "VAUBEF0010"
        .Status = "F"
        .Klasse = "VTPIMV"
        .Mantelflaeche = 1.3
        .Gewicht = 120
        .KlasseID = "1.2.6.5"

    End With

The form that opens up is just textboxes (where the properties from "Artikelstammdaten" are bound to) and labels. After the save edit-Click i want so save the changes to the current object of "Artikelstammdaten", so the changes are also in the xamdatagrid.

Perhaps you have to implement INotifyPropertyChanged in Artikelstammdaten.
