Working with the MapView control in the ArcGIS Runtime

This is the third in a series of posts covering the new ArcGIS Runtime SDK. In part 2, I discussed the basic mapping layers within the ArcGIS Runtime. Now that we know how to add a map and layers to your app, let’s see what we can do with the map! As I mentioned in the first post, the new ArcGIS Runtime has a MapView, rather than a Map that you put in your app. The MapView has a Map property that must be set, but all of the functionality lies in the MapView. We’ll start out with some of the key dependency properties. We’ll then look at the map events, and finish with the few methods. Dependncy Properties The new MapView control has 11 dependency properties (with one additional attached dependency property). In this blog we’ll focus on seven of them. Not to worry about the other four. One we have already covered (Map), one will be covered in the next blog and two more when discussing GIS focused work. In this blog I’ll cover the following dependency properties. MapGrid Maximum... [More]

Getting started with the ArcGIS Runtime (beta) Mapping SDK for .NET

Last Sunday (March 9) Esri announced the public beta release of their mapping SDK for .NET. This new SDK covers Windows Store, Windows Phone, and WPF. Can you believe it? All three platforms, and all using the same API. This is huge news if you develop mapping applications. Personally I find it painful that in Windows Phone 7 you would use the Bing Maps (Silverlight) SDK. In Windows Phone 8 you were encouraged to use the new Nokia Maps SDK, while on Windows Store you had the Bing Maps SDK, but it was a different SDK than the Windows Phone 7 one. So that’s three different SDKs to use. I have no idea who thought this was a sane idea. Esri has been working hard on this new SDK. During the Devsummit last year (2014), Esri announced the beta of a new SDK that would target Windows Store. At that time, they already had a Windows Phone SDK and a WPF SDK. Both were very similar with a few extras on the WPF side. While working on this new beta for Windows Store, they decided it would be much be... [More]

Creating a behavior to capitalize text

Many apps get data that they show from services. These services generally have their data cased a certain way. If you want to navigate to a page to show data, you may want to have the title of the page be information from the service. The title portion of the page tells the user that this is the profile for Shawn Kendrot. The text for “Shawn Kendrot” came from the service and is cased in Title Case. But if you wanted to follow design guidelines (which are not a requirement), you may want the name to be all upper case. To accomplish this you have three options, convert the text when you download it, create a value converter, or create a behavior. The first is really not an option, because that means that you can no longer use that text for anything else. Value converters are nice, easy to use, and sometimes overused. Behaviors are nice because they can easily be used within the designer of Blend. If you are not familiar with Blend, you should find time to use it. It is the tool to ... [More]

Managing Extents within the ArcGIS WPF/Silverlight/etc. APIs

Managing extents within the ArcGIS .Net client API’s is pretty simple. Esri has an example on the resources page. I implemented one for the ArcFM Silverlight SDK sample. Oddly enough, they are quite similar. I don’t remember copying theirs, but you never know. Like most things we as developers do, after a couple of years you look back and wonder “What was I thinking?” I look back at my original code and wonder why did I implement the Extents class the way that I did. I originally used one List to hold all of the Extents. This made some of the code pretty ugly. I’ve created a different implementation that utilizes two stacks. I have one class that manages all of the extents: 1: public class Extents 2: { 3: private readonly Stack<Envelope> _backStack = new Stack<Envelope>(); 4: private readonly Stack<Envelope> _forwardStack = new Stack<Envelope>(); 5:  6: public bool HasPrevi...
