This example demonstrates how to calculate a route between several waypoints and change the appearance of a route path using the Microsoft Bing Route web service. To accomplish this, do the following.
MainWindow.xaml.vb |
Public Sub New()
InitializeComponent()
' Create three waypoints and add them to a route waypoints list.
Dim waypoints As New List(Of RouteWaypoint)()
waypoints.Add(New RouteWaypoint("New York", New GeoPoint(41.145556, -73.995)))
waypoints.Add(New RouteWaypoint("Oklahoma", New GeoPoint(36.131389, -95.937222)))
waypoints.Add(New RouteWaypoint("Las Vegas", New GeoPoint(36.175, -115.136389)))
routeProvider.CalculateRoute(waypoints)
End Sub
Private Sub routeProvider_LayerItemsGenerating(ByVal sender As Object, ByVal args As LayerItemsGeneratingEventArgs)
Dim letter As Char = "A"c
For Each item As MapItem In args.Items
Dim pushpin As MapPushpin = TryCast(item, MapPushpin)
If pushpin IsNot Nothing Then
pushpin.Text = letter.ToString()
letter = ChrW(AscW(letter) + 1)
End If
Next item
End Sub
