00:01I'm going to use Flex to highlight some of the new functionality at 10.1.

00:04One of the cool things is dynamic layers.

00:06At 10.0, we supported dynamic map services where you could turn on and off layers.

00:11With 10.1, and the dynamic layer capability, you can the symbology on the fly.

00:16You can change the order of the layers, and you can even add layers on the fly.

00:20Let me show you how.

00:24In this application, I'm using dynamic layers, and each time I pan...

00:28...the rendering is being sent to the server, and the server is creating this image.

00:32To see the performance, we can change the number of classes, can change the number of the colors...

00:42...change the colors, and as I change the colors, the map updates pretty quick.

00:47This is ArcGIS Server 10.1.

00:50Let me show you some code for doing this.

00:55In Flash Builder, I'm writing this custom widget.

00:59I'm taking advantage of some of the new functionality at 10.1, layer drawing options.

01:03And it's quite simple. There's two steps. The first one is to specify which layer I want to use.

01:08And the second step, what renderer do I want to use to this.

01:12I add it to my map, and the map refreshes. Pretty straightforward. And this is the map you have.

01:26You might recognize this application as a Flex viewer application.

01:29Many of you have already used the Flex viewer. It's been out for quite a few years...

01:33...and it's got a lot of feedback, a lot of people using either configuration files or writing source code in Flash Builder.

01:39This here is the 3.0 prerelease version that was released last week.

01:44It has a new few new features, but one of the best features, I think, that we added last year was an Application Builder.

01:52The Application Builder allows you to easily assemble Flex viewer application.

01:57The first step is to create an application, is create the folder where it copies out all the application files that are needed...

02:05...and you could just either edit them manually or you can use the Application Builder to edit things.

02:11I'm going to create the map with a few basemaps.

02:15I'm going to add an operational layer.

02:17In this case, it's a layer that supports dynamic layers.

02:20This is a capability that you enable when you publish your map service.

02:27It's an American service so I'm going to zoom into the US, I'm going to save it.

02:32We've improved the widgets to support 10.1 functionality.

02:35For example, the Edit widget supports owner-based access control and a lot of other new features at 10.1.

02:41The Geoprocessing tool...widget has been updated to support the new geoprocessing functionality.

02:47And the Print widget supports high-quality PDF printing.

02:53For this demo, I've also added the custom widget I created in the last application.

02:58Being able to support custom widgets in Application Builder is a new feature for the 3.0 final release.

03:06In this case, I just make sure it points to my service that I've added. I save it.

03:13I go to preview it in a browser, and I should have an application very similar to the one I created...

03:20...the one I created in the...there we go...created from Flash Builder directly.

03:31Last year, not only did we add the Application Builder, we also open sourced our Flex viewer.

03:40All the code is available on GitHub. You can download it, you can access it...

03:45...compare it to the later versions, a strong capability.

03:48And we hope you take advantage of GitHub to enable also feedback to our Flex viewer code.
