ZoomTo Object in DataGrid Table

DidumAbraham — Fri, 12 Nov 2010 18:31:55 GMT

I have an item in a datagrid table and I'm trying to use the itemClick event to zoom-in to each item on the map when clicked on the item. Has anyone worked similar proejct?

var myGra:ArrayCollection = myGraphicsLayer.myGra as ArrayCollection;
          var myGraExt:Extent = GraphicUtil.getGraphicsExtent(myGra.toArray());
          myMap.extent = myGraExt.expand(2.4);

However, this approach from esri samples zooms to all features instead of each individual item.

I'm assuming that you are populating the DataGrid.dataProvider with QueryTask.executeLastResult.attributes and the features on the map are on a GraphicsLayer with the graphicProvider populated by QueryTask.executeLastResult.features. If that's the case, in the itemClick handler you can loop through and try to match some unique ID in the features with a unique ID of the attribute clicked on in the DataGrid, like this:

for each(var feature:Graphic in queryTask.executeLastResult.features)
{
 if(feature.attributes.ID== event.itemRenderer.data.ID)
 {
  myMap.extent = feature.geometry.extent;
 }
}

I'm not using QueryTask.executeLastResult.attributes, but I am using findTask. Here is sample code...

private function doFind():void {
 var FindParams:FindParameters = new FindParameters();     FindParams.contains = true;
 FindParams.layerIds = [0];
 FindParams.outSpatialReference = myMap.spatialReference;
 FindParams.returnGeometry = true;
 FindParams.searchFields = ["*"];
 FindParams.searchText = findTxt.text;
 findTask.execute(FindParams);  //
<!-- Find Tasks -->
            <esri:FindTask id="findTask" showBusyCursor="true" 
 executeComplete="{findHandler(event);}"
 url="rest/api/server..."/>

private function findHandler(event:FindEvent):void {
 myGraphicsLayer.clear();  
 //resultSummary.text = "Results found: " + event.findResults.length;  
 myGraphicsLayer.symbol = sfsFind;
 var resultCount:int = event.findResults.length;
 if (resultCount == 0) {
       Alert.show("Search not found. \nPlease select the correct \nradio button and retry!");
 } else {
              var myFeatures:ArrayCollection = new ArrayCollection();
  for(var k:int=0; k < resultCount; k++){ 
               var cntr2:Number = (k+1);
   bottomPanel.title = "Length of features : " + resultCount.toString();
   myFeatures.addItem(
    {
  COUNT: cntr2,
  YEAR_BUILT: FindResult(event.findResults).feature.attributes.YEAR_BUILT,
  UKEY: FindResult(event.findResults).feature.attributes.UKEY,    ADDRESS1: FindResult(event.findResults).feature.attributes.ADDRESS1
   }
  );
  myGrid.visible = true;
  myGrid.dataProvider = myFeatures;
  }

<mx:DataGrid id="myGrid" visible="false" width="100%" color="0x006699"
     itemClick="myGrid_itemClick(event)" editable="false">   
     <mx:columns>
      <mx:DataGridColumn width="40" dataField="COUNT" headerText="#"/>
      <mx:DataGridColumn width="45" dataField="YEAR_BUILT" headerText="Year"/>
      <mx:DataGridColumn width="45" dataField="UKEY" headerText="Key"/>
<mx:DataGridColumn dataField="ADDRESS1" headerText="City Name"/> 
     </mx:columns>
    </mx:DataGrid>

private function myGrid_itemClick(event:ListEvent):void {   
    if(event.columnIndex >= 0){
     var graphicProvider:ArrayCollection = myGraphicsLayer.graphicProvider as ArrayCollection;
     var graphicsExtent:Extent = GraphicUtil.getGraphicsExtent(graphicProvider.toArray());
     myMap.extent = graphicsExtent.expand(2.4);
     myGraphicsLayer.symbol = smsFind;
    }
   }
