I have a ListView that is bound to a dataset. The user has ability to select multiple rows. I would like when a button is clicked, delete all selected items. For that I use a loop but get error message: Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead. The code looks

My ListView has chechbox column and I would like to select some rows in ListView and delete them by click Delete button. That is code of Delete procedure.

  Private Sub DeleteSvcButton_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles DeleteSvcButton.Click  
  If Not IsNothing(Me.ListView1.SelectedValue) Then
   If ListView1.SelectedItems.Count > 0 Then
    For i As Integer = 1 To ListView1.SelectedItems.Count
     Dim TestDataRow As System.Data.DataRowView
     TestDataRow = ListView1.SelectedItems(i - 1)
     Service_Id = Me.ListView1.SelectedValue
    Next
   End If

   If MsgBox("Are you sure you want to delete this row", MsgBoxStyle.YesNo, "Are You Sure?") = MsgBoxResult.Yes Then
