I have a XamDataGrid
in my MainWindow which has a Public Shared List(Of Artikelstammdaten)
as DataSource
. After opening a few other forms I want to add more data to the XamDataGrid
with a button click. I thought the easiest way would be just to update the DataSource
, but I get an Error:
The reference to an unreleased member requires an object reference.
This is what I have tried:
Private Sub Add_Click(sender As Object, e As RoutedEventArgs)
Dim update = MainWindow.listArtikelstammdaten.Concat(CType(Import.ComparedAccessData, IEnumerable(Of Artikelstammdaten)))
dgArticleMasterData.DataSource = update
Me.Close()
End Sub
CodePudding user response:
If dgArticleMasterData
is defined in the MainWindow
class, you need to get a reference to the MainWindow
instance to be able to access it.
You should be able to find it in the Application.Current.Windows
collection:
Private Sub Add_Click(sender As Object, e As RoutedEventArgs)
Dim update = MainWindow.listArtikelstammdaten.Concat(CType(Import.ComparedAccessData, IEnumerable(Of Artikelstammdaten)))
Dim window = Application.Current.Windows.OfType(Of MainWindow).FirstOrDefault()
If window IsNot Nothing Then
window.dgArticleMasterData.DataSource = update
End If
Me.Close()
End Sub
