I have used network analyst tool box as can be seen in attached model. This model is working fine. when i run it under ArcMAp it gives me routes and stop and also draws routes between two given point. I published it as synchronous geoprocessing service and accessed it in flex application. I provide the required parameter and execute the task using execute method. it returns me the length of the route. however i also want to draw the route between two points in my flex application. Please see the attached model and below is the geoprocessing detail. Now is there any suggestion how i can draw the route in my flex application:
thanks.
code that I using in the flex web application to read the route length is :
private function SolveRoutes_Complete(event:GeoprocessorEvent):void
{
parameterValue = event.executeResult.results[0];
fset = FeatureSet(parameterValue.value);
for each ( var myfset:Graphic in fset.features) //event.parameterValues[0].value.features )
{
Alert.show("Rname"+ myfset.attributes.RouteName + "Clength"+ myfset.attributes.Cumul_Length);
}
}
