Is there a way to dynamically name/control checkboxes in visual basic?

Question

I have xaml code that creates a list view with two columns; the first column is checkboxes based on the number of items that are in the second column. The issue with the way the code is written is the checkboxes do not have their own names (as far as I can tell). If i rename the object then all 15 of the checkboxes will be named the same thing not allowing me control over what happens if any one is checked (I think). Is there a way I can code it to where they have independent control from one another?

This is what I used to create this far

<Grid>
   <ListView Grid.Row="2" Grid.Column="2" ItemsSource="{Binding XPath=..//@ParentAttribute}">
      <ListView.View>
         <GridView>
            <GridViewColumn Header="Selection">
               <GridViewColumn.CellTemplate>
                   <DataTemplate>
                      <CheckBox Name="Check"/>
                   </DataTemplate>
               </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <GridViewColumn>
            </GridViewColumn>
         </GridView>
      </ListView.View>
   </ListView>
</Grid>

You can add an event handler to your CheckBox:

<DataTemplate>
    <CheckBox Name="Check"
                Checked="Check_Checked" />
</DataTemplate>

In your code-behind, this will create a Check_Checked event handler:

Private Sub Check_Checked(sender As Object, e As RoutedEventArgs)

    If e.Source.GetType = GetType(CheckBox) Then

        Dim checkBox As CheckBox = CType(e.Source, CheckBox)
        Dim xmlElement As XmlElement = CType(checkBox.DataContext, XmlElement)

        MsgBox(xmlElement.OuterXml)

    End If

End Sub

One this event is raised, the DataContext of the CheckBox that was checked will be an XmlElement. From this you should be able to retrieve anything you need from the item that was clicked.

Here's a simple WPF Window I built with XML I got from this Microsoft example:
