Using the Locate Widgets results, to populate the datagrid in the Identify Widget

JamesHolley · ‎01-17-2012

I would like to pass the x,y map point generated when a user searches for their address to populate the identify widget's datagrid with information such as parcel, zoning, and land Use. I am currently using flex api 2.3.1

Any help would be great.

James,

Just add this one line in the code below:

            private function sharedDataUpdated2(event:AppEvent):void             {                 var dataTable:Hashtable = event.data.data as Hashtable;                 if (dataTable.containsKey("Find U.S. address"))                 {                     var recAC:ArrayCollection = dataTable.find("Find U.S. address") as ArrayCollection;                                          var locateResult:* = recAC[0];                     var mPoly:Polygon = new Polygon(null);                     // The tollerance of 12 is all dependant on how big of a right of way there                     // is from the road                     var ext2:Extent = createExtentAroundMapPoint(locateResult.point, 12) as Extent;                     var pA2:Array = [];                     pA2.push(new MapPoint(ext2.xmin,ext2.ymin,ext2.spatialReference));                     pA2.push(new MapPoint(ext2.xmin,ext2.ymax,ext2.spatialReference));                     pA2.push(new MapPoint(ext2.xmax,ext2.ymax,ext2.spatialReference));                     pA2.push(new MapPoint(ext2.xmax,ext2.ymin,ext2.spatialReference));                     pA2.push(new MapPoint(ext2.xmin,ext2.ymin,ext2.spatialReference));                     mPoly.addRing(pA2);                     mPoly.spatialReference = ext2.spatialReference;                     clear();                     identifyFeatures(mPoly);                 }             }

James,

First things first. You should post all Flex Viewer and/or Widget Questions to the Flex Viewer Forum here:

http://forums.arcgis.com/forums/111-ArcGIS-Viewer-for-Flex

What you are asking is doable but will require a lot of custom code do you have any experience customizing widgets in Flex?

Robert,

I do have some experience customizing widgets but not a lot. I am learning as I go. If you could provide any help or a starting point that would be great.

Thanks

James,

This is going to be a little complicated and you will have to add code in both widgets (the locate and the Identify widget). Are you using the standard otb (out of the box) locate widget? Are you going to have your Identify widget preloaded?

MLowry · ‎01-20-2012

I have used Robert's code and developed a widget that accepts address or lat/long or they click a point on the map, and then they input buffer parameters, and it sends they buffer to the search widget and then to a datagrid. Is this similar to what you're trying to do?

JamesHolley · ‎01-20-2012

Robert,

The Locate widget I am currently using is modified slightly to work with our current projection, but other than that it is standard. I will have the Identify widget preloaded.

Thanks again

James,

So here it is, I ended up only having to add code to the Identify widget and I tried to comment all my changes. The big thing is this line needs to be the name of your locate widget:

if (dataTable.containsKey("Find U.S. address"))

What you are attempting to identify needs to be on and visible. Basically when you locate an address the XY map point is fired off to the identify widget and buffered 12 units in attempt to get far enough away from the street center line to pickup a parcel.

Don't forget to click the top arrow (promote) and to click the Mark as answer check as shown below:

Robert,

Thank you for taking the time to help me with this project. I will try to make these changes today and let you know how it goes.

Thanks again

Robert,

I tested the .mxml an it returned these errors. Do you have any advice on how to fix these? Any help would be great.

Identify.mxml
