Unfortunately WP7 is based on Silverlight 3. So we can't use some nice features of Silverlight 4 i.e. dynamic key word or TextBlock's trimming. But I've solved issue with trimming for Silverlight 3. Solution is here. Let me explain which code I use in WP7 project:
- Generic.xaml: File contains style and template for custom control. This file is located in Themes folder. WP7 tools doesn't contains Resources.xaml file template. So I created xml file and name it as "Generic.xaml".
- TrimmedTextBlock.cs: It is implementation of custom control. I just copied this file. One more note: I decrement c_POINTS_COUNT to "1" because screen resolution of desktop and mobile versions are different.
