Swipe Tool in ActionIt’s been  a while since my last blog post thanks to Twitter.  This week I posted a new sample on the JavaScript Code Gallery ( called “Swipe Tool”. As the name suggests its a swipe tool and if you are familiar with ArcGIS Desktop or ArcGIS Explorer you know what this means, for other its a way to see what underneath a layer. Can be used as a good comparison tool.

New sample : GeoIP + ArcGIS – Where Am I

New sample shows how to use the free GeoIP service to find the location and show the lat/lon of the visitor on a map. Here is the link to the sample :

If you go to my homepage you can see how I have used the smaller version of the sample inside of a page using an iframe to locate the website visitors. Feel free to copy the code and use it in your site.

Devsummit 2009 Demo – infoTips posted on code gallery for download

Just posted a new sample on code gallery. This sample was demoed in the devsummit 2009 session and as promised I have upload a zip file with samples, documentation and source file.

Here are quick links to the sample :

Rate the sample and post any comments directly at that site or here in my blog. Based on the comments I will add more functionality to the infoTip class.

Working with

Few common scenarios when you are working with the graphics layer (@ version 1.3) in the ArcGIS Server JS API

1. returns the graphics layer
2. returns the array of graphic elements (geometry, symbol, attribute, infotemplate) added to the graphics layer

To remove all graphic elements in the graphic layer;

To show/hide specific graphic element[index].show();[index].hide();

To check if any specific graphic element is being shown or not:
// 'none' is hidden and 'block' is visible[index].getDojoShape()

Loop through all the graphic elements
var graphics =;
for (var i=0; i< graphics.length; i++)
// do something with graphics[i]

even better

dojo.forEach(, "console.log(item.getDojoShape()");
dojo.forEach(, "console.log(item,index,array)");
dojo.forEach(, function(item){//item is a graphic element });

Note: @version 1.4 you will have ability to add multiple graphics layers (in addition to the default graphics layer) and can control the stack order (z-index).

Ready to use Sample layouts using Dojo

Just posted a blog entry on the ArcGIS Server Blog. Check it out.

Blog talks about how to use Dojo Dijits – BorderContainer (dijit.layout.BorderContainer) and ContentPane (dijit.layout.ContentPane) to design your layouts for application. I have created a bunch of sample layouts with most of the commonly used layouts, check out the links below.
