Hi, I am trying to route added markers from user. When the user finishes to adding markers click to getRoute button and then I try to route the markers but I could not do it. Also I want to know if it is possible to route as soon as the user add the second, third and n marker without clicking getRoute button. thanks.

Routing User's added markers
Ayhan,
We found it’s a bug from RoutingViaVisitStops method and we have fixed in the latest version, please get it (4.5.121.0 or later) and have another try with the attached sample.
Basically, the attached sample is modified upon the HowDoI Samples of MapSuiteRouting web samples, DifferentProjectionsWithRouting. To run this sample, you need to copy the file “AustinStreets.shp” and the associated files to the SampleData folder contained in the solution. You can focus on the methods Map1_Click and FindPath where your requirement is implemented.
Further questions please let me know.
Thanks.

Thank you James,
James, The latest version that we have 4.5.120.0 not 4.5.121.0 and I tried the sample with version 4.5.120.0, it works fine just only when I add third marker it waits for routing about 7-8 minutes but after routing third marker it works fine for other markers (fourth, fifth, sixth …)
If the version that we have it has that bug so I am waiting for the latest version.
Thanks,
Ayhan
Ayhan,
Yes, that’s the bug I mentioned in earlier post and version 4.5.121.0 is already available now. You can download and try this version which has this bug fixed.
Further questions please don’t hesitate but give us a post.
Thanks.
James
