Hi there,

 

I have read that it should be possible to add 'Viawaypoints' in combination in normal 'Waypoints'.

I however cannot find a c# method other than  'reqRoute.Waypoints.Add(l_sWaypoint);'

What is the right manner to have more than 25 waypoints in my route?

 

Kind regards,

Victor

Hello Victor, 

Thank you for writing.  

Currently, RadMap doesn't support ViaWaypoints. However, it is a reasonable request. I have logged it in our feedback portal and I have added a vote for it on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to create a custom BingRestMapProvider and override its BuildRoutingRequestUri method where you can add the ViaWaypoints. Here is demonstrated a sample approach:

public class CustomBingRestMapProvider : BingRestMapProvider
{
    protected override Uri BuildRoutingRequestUri(RouteRequest request)
    {
        List<string> waypoints = new List<string>();
 
        foreach (string str in request.Waypoints)
        {
            waypoints.Add(str.ToString());
        }
 
        request.Waypoints.Clear();
 
        Uri result = base.BuildRoutingRequestUri(request);
 
        StringBuilder path = new StringBuilder();
 
        for (int i = 0; i < waypoints.Count; i++)
        {
            if (waypoints[i].StartsWith("#VIA#"))
            {
                path.Append("&vwp." + i + "=" + Uri.EscapeDataString(waypoints[i].Substring(5)));
            }
            else
            {
                path.Append("&wp." + i + "=" + Uri.EscapeDataString(waypoints[i]));
            }
        }
 
        string uri = result.AbsoluteUri;
        uri = uri.Insert(uri.IndexOf('?') + 1, path.ToString() + "&");
 
        return new Uri(uri);
    }
}
 
public void RunRouteRequest()
{
    //add a layer to display the route
    this.radMap1.MapElement.Layers.Add(new MapLayer());
    RouteRequest request = new RouteRequest();
    request.DistanceUnit = DistanceUnit.Kilometer;
    request.Options.Mode = TravelMode.Driving;
    request.Options.Optimization = RouteOptimization.Time;
    request.Options.RouteAttributes = RouteAttributes.RoutePath;
    request.Options.RouteAvoidance = RouteAvoidance.None;
    
    request.Waypoints.Add("Paris, France");
    request.Waypoints.Add("#VIA#Madrid, Spain");
    request.Waypoints.Add("Vienne, Austria");
    BingRestMapProvider bingProvider = this.radMap1.Providers[0] as BingRestMapProvider;
    bingProvider.CalculateRouteCompleted += BingProvider_RoutingCompleted;
    bingProvider.CalculateRouteAsync(request);
}

I hope this information helps. Should you have further questions I would be glad to help.

 Regards,
Dess

Hello, Victor, 

As the status of the feedback item states, the item has already been completed. The feature was introduced in R2 2018 SP1 (version 2018.2.621). Here is the release history for your reference: https://www.telerik.com/support/whats-new/winforms/release-history/ui-for-winforms-r2-2018-sp1-(version-2018-2-619)

The RouteRequest now offers the RoutePoints property where each element represents a stop in the route. The elements could be Waypoint or ViaWaypoint.
 
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
