I have a WPF form that has a List Box populated with data from an XML file. The XML file contains an element called 'Status', which can be either 'a-current' or 'b-finished'. I have the code below to change the context menu header based on the 'Status' element content, but I can't seem to figure out how to get the click of the header to run a certain sub.

Private Sub lstJobs_MouseRightButtonUp(sender As Object, e As MouseButtonEventArgs) Handles lstJobs.MouseRightButtonUp
        Dim o As ObjectDataProvider
        Dim j As Job = lstJobs.SelectedItem
        Dim cMenu As New ContextMenu, mi1 As New MenuItem

        If j.Status = "a-current" Then
            'MsgBox(j.Status)
            mi1.Header = ("Mark as _Finished")
        Else
            'MsgBox(j.Taken)
            mi1.Header = ("Mark as _Unfinished")
        End If

        cMenu.Items.Add(mi1)

        lstJobs.ContextMenu = (cMenu)

    End Sub

How do I process the selection of the context menu item?
