{
  Button button = (Button)sender;
  ColorItemList colorList = (ColorItemList)button.DataContext;
  CollectionView cv = (CollectionView)CollectionViewSource.GetDefaultView((IEnumerable)colorList);

' Event handler for the NewColor button
Private Sub OnNewColorClicked(ByVal sender As Object, ByVal args As RoutedEventArgs)
  Dim button As Button = CType(sender, Button)
  Dim colorList As ColorItemList = CType(button.DataContext, ColorItemList)
  Dim cv As CollectionView = CType(CollectionViewSource.GetDefaultView(CType(colorList, IEnumerable)), CollectionView)

  ' add a new color based on the current one, then select the new one
  Dim newItem As New ColorItem(CType(cv.CurrentItem, ColorItem))
  colorList.Add(newItem)
  cv.MoveCurrentTo(newItem)
End Sub

Remarks

If the specified item is not found, the method returns false and the CurrentItem is positioned before the beginning of the collection in the view.

Collection views support the concept of a current record pointer. As you navigate through the objects in a collection view, you are moving a record pointer that allows you to retrieve the object that exists at that particular location in the collection. For more information, see "Binding to Collections" in Data Binding Overview.

For more information about the current item of a view, see CurrentItem.
