How to zoom to a selected record after click in a popup DataGrid

varnavarna

Hi,

We are trying to make a popup DataGrid to be clickable and center the map on the selected parcel. I'm trying to modify the code from those two great threads --> http://forums.arcgis.com/threads/10377-How-to-zoom-to-selected-record-on-Data-Grid-result?p=35685&posted=1#post35685 and http://forums.arcgis.com/threads/11765-How-to-make-mouserover-on-map-amp-highlight-popup-datagrid?p=35962#post35962

There is a problem with communication between the application and the popup window. There is a click event in the DataGrid which leads to this function:

private function sfDataGrid_Click():void
            {
                var obj:Object = sfDataGrid.selectedItem;
                if (obj != null)
                {
                    lastIdentifyResultGraphic = null;
                    
                    query.where = "STATE_NAME = '" + obj["STATE_NAME"] + "'"
                    queryTaskZoom.execute(query, new AsyncResponder(onResult, onFault));
                    function onResult(featureSet:FeatureSet, token:Object = null):void
                    {
                        lastIdentifyResultGraphic = featureSet.features[0];
                        lastIdentifyResultGraphic.symbol = sfs;
                        MainMap.extent = new Extent(lastIdentifyResultGraphic.geometry.extent.xmin,lastIdentifyResultGraphic.geometry.extent.ymin,lastIdentifyResultGraphic.geometry.extent.xmax,lastIdentifyResultGraphic.geometry.extent.ymax);
                    }
                    function onFault(info:Object, token:Object = null):void
                    {
                        Alert.show(info.toString(), "Query Problem");
                    }
                }
            }

but when I click in the popup while debugging I get a "TypeError: Error #1009: Cannot access a property or method of a null object reference." at component

query.where = "STATE_NAME = '" + obj["STATE_NAME"] + "'"

Any ideas what we are doing wrong?

Thank you!

Hey!

I was able to find a solution to the problem.

I used the parentApplication property in the query and queryTaskZoom and it started transfering the clicks in the main App

Here is the changed function:

private function sfDataGrid_Click():void
            {
                var obj:Object = resultsGrid.selectedItem;
                if (obj != null)
                {
                    lastIdentifyResultGraphic = null;
                    
                    parentApplication.query.where = "Owner_Name = '" + obj["Owner_Name"] + "'"
                    parentApplication.queryTaskZoom.execute(parentApplication.query, new AsyncResponder(onResult, onFault));
                    function onResult(featureSet:FeatureSet, token:Object = null):void
                    {
                        lastIdentifyResultGraphic = featureSet.features[0];
                        lastIdentifyResultGraphic.symbol = sfs;
                        parentApplication.myMap.extent = new Extent(lastIdentifyResultGraphic.geometry.extent.xmin,lastIdentifyResultGraphic.geometry.extent.ymin,lastIdentifyResultGraphic.geometry.extent.xmax,lastIdentifyResultGraphic.geometry.extent.ymax);
                    }
                    function onFault(info:Object, token:Object = null):void
                    {
                        Alert.show(info.toString(), "Query Problem");
                    }
                }
                
            }
