Hallo zusammen,
habe das Problem nach schwieriger Suche gelöst.

Hier ist der Code:
XAML:
<Window x:Class="FormSearchPart"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Search Part" Height="345" Width="365" ResizeMode="CanResize" MinHeight="345" MinWidth="365" Background="GhostWhite" Name="FormSearchPart">
<Grid>
<ListView Margin="12,100,12,41" Name="lstResultParts">
<ListView.View>
<GridView>
<GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Description}" Header="Description" />
<GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Price}" Header="Price" />
<GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Remarks}" Header="Remarks" />
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>Code Behind:
Imports System.Data
Public Class FormSearchPart
Public Sub New()
Dim lstParts As New List(Of listPartResult)
InitializeComponent()
' Fügen Sie Initialisierungen nach dem InitializeComponent()-Aufruf hinzu.
lstParts.Add(New listPartResult("Description #1", 9.78, "Remarks #1"))
lstParts.Add(New listPartResult("Description #2", 12.45, "Remarks #2"))
lstResultParts.ItemsSource = lstParts
End Sub
End ClassList-Klasse
Public Class listPartResult
Private _strDescription As String
Public Property Description() As String
Get
Return _strDescription
End Get
Set(ByVal value As String)
_strDescription = value
End Set
End Property
Private _dblPrice As String
Public Property Price() As String
Get
Return _dblPrice
End Get
Set(ByVal value As String)
_dblPrice = value
End Set
End Property
Private _strRemarks As String
Public Property Remarks() As String
Get
Return _strRemarks
End Get
Set(ByVal value As String)
_strRemarks = value
End Set
End Property
Public Sub New(ByVal strDescription As String, ByVal dblPrice As Double, ByVal strRemarks As String)
_strDescription = strDescription
_dblPrice = dblPrice
_strRemarks = strRemarks
End Sub
End Class
Habe es im Netz gefunden und an meine Bedürfnisse angepasst.
Wieso es vorher nicht geklappt hat, weiß ich nicht.
Auf jeden Fall klappt es jetzt.

Ich melde mich, sobald ich weitere Fragen habe.

Viele Grüße
