With Silverlight 4 came support for Text Trimming. Text Trimming is a feature that applies to TextBlocks and is used to append “…” at the end of the string if the text in the TextBlock does not fit. In WPF this can be done at the character level or the word level. Silverlight 4 only supports trimming at the word level.

The feedback from the Silverlight 4 application themes released and the latest in process have been overwhelmingly toward the positive.  We appreciate the feedback and hopefully you appreciate the transparency in the process.  As a developer I want my fellow brethren to appreciate good design and use it whenever possible … even as a default if you don’t have designers on board.

My approach to View-First ViewModel creation has evolved over time.  I have constructed ViewModels in code-behind.  I have instantiated ViewModels in the resources sectoin of the view. I have used Prism to resolve ViewModels via Dependency Injection. I have created attached properties that use Dependency Injection containers underneath.  Of all these approaches, I continue to find issues either in composability, blendability or maintainability. 

Feel free to use this plugin as you like. It is a simple plug in that shows information about the Twitter user right inline with the Tweet. This post will explain what the Sticky plugin does and of course I’ll share the plugin with you. I’ll follow up with another post to explain how to create a plugin using the Seesmic Desktop platform, Visual Studio 2010, and Expression Blend.

It's not a secret that one of my favorite Silverlight 4 features is the webcam support and I already played endless hours with it. There are many blog posts out there demonstrating how to use the webcam and how to take a screenshot with the CaptureImageAsync method. Only a few cover the VideoSink.

Mark has worked on the text aspects of Silverlight since the first version. Here are just a few of the areas that Mark covers:

1. Overview of RichTextBox vs. TextBlock and TextBox for rich content
2. Wire-up logic for applying formatting
3. Inline UI elements
4. Using text position to point for simple and complex operations [...]

This is a minor release that addresses some items found immediately after release that have now completed our test passes with those who reported them. Most of the items found won’t affect all users, but media developers will want to get this update for their applications and encourage their users to upgrade.

Blend 4.0 includes a new PathListBox control. In Silverlight 4 you can create your own shapes by deriving from the Path class. I have used these two techniques to create this SpiralText sample.

The Spiral class uses ArcSegment objects to create a spiral illusion. It isn't a perfect spiral but it is good enough for me.
