Passing Parameter to Flex Viewer

[CurtNielsen]

I would like to pass a parameter, parcel id, to flex viewer and have the map pan to that location. I have modified the Search widget to use a layer that we can search by parcel ID. Just want the same capability if I pass a parameter, paracle ID, to http://mynode/FlexViewer. Maybe something like http://mynode/FlexViewer?request=widget&version=2.1&WidgetName=Search&ParcelID=1234

Thank you!

Curt,

   Here are four different threads that deal with your question. No sense re-inventing/re-writing the wheel.

I've been looking at this because I also want to be able to pass a parcel ID to open a map viewer to the associated parcel, but all the code in the previous discussions pertain to the SFV.  How can this be applied to the v2.2 Flex Viewer?

Thanks,
Marc

Hi Marc, I am looking to do the same thing.  Did you have any luck with 2.2?

Steve,

I've been working on other things while waiting for any reply.  Nothing yet.  Today I'm trying to apply what appears to be the simplest solution, one posted by Rick Diaz for the 1.3 sample viewer in this thread: http://forums.esri.com/thread.asp?c=158&f=2421&t=266031&mc=47  It only requires modifying MapManager.mxml (I'm leaving out the progress bar for now). 

The main challenge I'm having is looking at the compile errors to figure out what needs to be modified to catch up to the API changes.  I really don't know what to expect in terms of functionality if and when I do get that all figured out.  Plus, I'm no developer so I'm totally winging it here.  If I get something work, I'll post it, but I'm still hoping a more skilled person will beat me to it.

Has anyone successfully been able to pass bounding coordinates to the 2.2 Flex Viewer in a URL? It looks like Jason never got it working in SFV 1.3 in http://forums.esri.com/thread.asp?c=158&f=2421&t=266031&mc=47#818760

I want to be able to have a URL to jump to each feature within my map. Since the size varies considerably from feature to feature, I think it will be easier to use bounding coordinates than center and scale (since I can easily calculate bounding coordinates using Field Calculator, and the map will jump to the nearest scale).

I have a vague memory that ESRI was considering enabling this for the 2.3 release, is that true?

Jon,

   Sure here is the code to change in the MapManager.mxml

            //map load complete
            private function mapLoadComplete(event:MapEvent):void
            {
//My Add
    map.zoomSliderVisible = false;
    map.logoVisible = false;
    
    try
    {
     if (ExternalInterface.available)
     {
      var timer:Timer;
      var result:URLVariables = new URLVariables();
      var urlSubstring:String = ExternalInterface.call("window.location.search.substring", 1);    
      if (urlSubstring && urlSubstring.length > 0 && urlSubstring != "debug=true")
      {
       result.decode(urlSubstring);
       // Parse URL
       var xExt:String;
       var xUrlParam:String;
       if (result["EXT"])
        xExt = result.EXT;
       
       if (!xExt == ""){
        var extArray:Array = xExt.split(",");
        var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),map.spatialReference);
        map.extent = extent;
       }
      }
     }
    }
    catch (error:Error){}
//End My Add
            }

to use it just append something like:  ?EXT=644988.5757,1173575.0875,645690.0041,1173863.1558 to the url.

Thanks Robert, that worked perfectly! I was also happy to see that something similar is natively supported with the ArcGIS.com web map:http://www.arcgis.com/home/webmap/viewer.html?url=http://maps.tnc.org/ecadpubprodanon/rest/services/...

It seems like several people have been interested in this topic so I'm going to update some other threads to point to your solution here.

Steve,

I've successfully modified the code to pass a parcel ID in the URL.  The map opens and zooms to the parcel which has been overlaid by a graphic. I'm attaching a text file with explanations and code.

Thank you very much Marc.  I will give it a go.
