Directions Component Stops Provider

[raffia]

Hello;

I am trying to provide a "Directions from here" and ..to here functionality, so I want to use the stopProvider property in the Directions Component. I tried passing an XY from the map point, but to no success. Any sample one line of code showing how to pass the stopProver please?

Raffi,

   I don't have a sample for this but the documentation says that the stopProvider is an object (ArrayCollection) of DirectionsStop objects. So just create some DirectionStop objects and add them to an array collection and pass that to the Directions component.

Thank you Robert for the reply. I will give that a shot and update this post.

Hi Robert and Raffi,
That will be so so cool. This is exactly what I am trying to do right now -- what a coincidence. I will definitely post an update if I come accross anything exciting or interesting.
Thanks.

Hello Koman;

Thanks for the post. Am planning to dive into this myself in two or three days, and will update here for sure as well.

Hi Raffi,
I started researching a bit this weekend, I came across these two ESRI docs, you may have seen these also. Maybe interesting...
They are passing xy values somehow manually to a graphic stops / featureset. I am assuming you could do the following:
If you have your xy in an arraCollection, you could loop the arrayCollection and add them directly to the graphic named stops

var stops:Graphic = new Graphic(new MapPoint(arraCollection.X, arrayCoolection.Y);
var stopsFS:FeatureSet = new FeatureSet([stops]);

Guys,

   Here is a sample seting the stops searchTerm to be geocoded.

Hi Robert,
This is just brilliant. Thanks a bunch.
In my particular case, I have a list of addresses that I have to pass to the stopProvider.
I think I will have to loop the arrayCollection list and while looping add them to thestopProvider.
But I see you have explicitly name the stops(stop1, stop2 etc.) not sure if they need to be named as such in my implementation ?
I am not in front of a computer right now, but do think the logic below will work?
While looping the arrayCollection:

PseudoCde
For(var i:int=0; i<arrayCollection.length; i++)
{
      var stop:DirectionStop=new DirectionStop();
      stop.searchterm=arrayCollection.Address,
      Dir.stopProvider.aadItem(stop);
}

Not sure if I need to explicitly declare the stops such as stop1, stop2 etc:
Var stop:DirectionStop=dir.stopProvider[1];
Hope you can enlighten me on that portion.
Just love the way you put your code together, brilliant.

Thanks in bunch.

Koman,

   The directions component always begins with two stops in the dataprovider so that is why I create explicit vars for those stops so that I can just manipulate them. One you have those two set then you can just add more the way I did for my third stop.

[KomanDiabate]

Excellent,
Now I understand why you declare the first two stops and just instantiate the third one. I will experiment with this on Tuesday at the office and see  if I can make it work using a collection of address. I appreciate your help on this.
Thanks a bunch.
