Hi: We have Tract polygons that we need to make boundary line... For example, we have 3000 Tract polygons that we show on the web (arcgis flex api)...Now user wants to make a boundary so that it shows a line only with the outer boundaries .. we created a geoprocessing service ( dissolves these polygons into one) ,, it works fine if number of polygons within around 1000... and does not work for higher numbers like 3000 polygons.. Is there any way make this possible on the web? Thanks Abu ... View more

HI: In my featurelayer, when the mode is onDemand, is there anyway to limit the maximum number of features that can be shown on this layer. if feauturelayer.graphicprovider.length > 2000, do not show this layer but below this number show this layer... ..(Note it is tied up with defintionexpression query that can bring potentially 50000 features... but want to bring only maximum 2000 features).. is there way to get this maximum number on the client side without changing the mapservice config file maxlimit to 2000) Also  what benifit do i  get by using onDemandCacheSize="2000"? Thanks... Abu ... View more

I have a dynamic layer...(say City)...Is there any way i can turn on/off the label (say name of cities) for this dynamic layer in code?  (Note I mean when i turn on label, it will show all the cities with label on this layer, and when i turn off label, it will not show any city label on this layer) Thanks ...

Hi : I need to render a graphic layer based on two graphic attribute fields, one attribute will be used for class range coloring (say for attribute, INCOME_PERCENT: when 0-25 yellow, when 26-50 blue, when 51-75 red) the second attribute will be used for different style on the same (say for attribute, DISTUNDER:   when under_served: horizontal strip,    when distressed: verticall strip,    no color for either case) Is that possible in flex api? Thanks. Abu ... View more

Hi: I load about 93000 points with clustering in the map... It takes less than a minute (fluorinefx, flex and .net).. However  i also need to decluster these points (to show the exact location of these points).. simply setting graphicslayer.clusterer = null  takes long time and some time (script out ).. NOw my questions are 1) it there way to de cluster only within a certain map extent (what I mean is  when user zooms in , i will decluster only points within the view extent ,, remaining points outside the view extent will still be clustered) 2) Is there any effiecient way to decluster? (may be for the entire area or within the extent) 3) any other idea? Thanks. Abu  Khan ... View more

HI: I am having two issues: issue 1: I showed tract polygons on the map using featurelayer..I showed the tract number for labels.. I used tract geometry.extent.center.x, and geometry.extent.center.y as the mappoint and used these mappoints for labels(with symbol set to textsymbol) Problem happens when we encounter such a geometry where center falls outside the polygon geometry.. In that case , the tract number shows in outside the polygon and difficult to know which one it belogs to.. Is there a way to fix it ??( I mean to get a mappoint that always falls inside the polygon..Note there is an algorithm to determine whether a point is inside a polygon by finding out if i crosss the boundary in odd number, but I can not implement that because I donot have points that comprise that polygon and also it will be killer for performance) issue 2: Two graphics layer --both layers got icons... Some of the icons in one layer falls on top of the icons of the other layer...Is there a way to separate them out? Thanks Abu Khan ... View more

say you have a graphiclayer where you populate graphic.. In the graphic add event can we add say attributes: var objc:Object = {MIN_P_ALL: myGraphic.attributes.MIN_P_ALL,  MIN_P_DEF: myGraphic.attributes.MIN_P_ALL, MIN_P_CUSTOM:myGraphic.attributes.MIN_P_ALL}; graphic.attributes = objc; Is graphic attributes writable? ...

Currently, classBreaksRenderer supports only attribute with the field name. example as follows: var classBreaksRenderer:ClassBreaksRenderer = new ClassBreaksRenderer(); classBreaksRenderer.attribute = "MIN_P_ALL"; Is there a way to implement attribute with some weight factor multiplied with the field: example say classBreaksRenderer.attribute = "MIN_P_ALL"*p; where p is postive weight factor Thanks..

I used infowindow for information of a feature layer on click event. The way i implemented is onMouseUp event on map:   private const infowindowscreen:mxmlpage = new mxmlpage (); private function onMouseUpMap(event:MouseEvent):void    { const mapPoint:MapPoint = MainMap.toMapFromStage(event.stageX,event.stageY);   Map.infowindow.content = infowindowscreen;   ---code to add values to all public variables on infowindowscreen-- Map.infowindow.show(mapPoint); } It works fine.. however the infoscreen sometimes go beyond the screen especially close to the edges. Is there a way automatically center it on the screen? ... View more
