Creating a behavior to capitalize text 30. September 2013 Shawn XAML (0) 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.

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]

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...
