This sample provides some sample text to select, and enables the user to toggle AutoWordSelection on and off. Use the mouse to select parts of the sample text with AutoWordSelection enabled and disabled, and observe the difference in selection behavior.
This sample demonstrates a specific feature of the Windows Presentation Foundation and, consequently, does not follow application development best practices. For comprehensive coverage of Windows Presentation Foundation (WPF) and Microsoft .NET Framework application development best practices, refer to the following as appropriate:

Install the Windows Software Development Kit (SDK) and open its build environment command window. On the Start menu, point to All Programs, Microsoft Windows SDK, and then click CMD Shell.
Download the sample, usually from the software development kit (SDK) documentation, to your hard disk drive.
To build the sample from the build environment command window, go to the source directory of the sample. At the command prompt, type MSBUILD.
To build the sample in Microsoft Visual Studio, load the sample solution or project file and then press CTRL+SHIFT+B.
When AutoWordSelection is enabled, each time part of a word is selected, the selection is automatically expanded to include that entire word. The user may override automatic selection of an entire word by momentarily reversing the direction in which the mouse pointer is being dragged as the selection is made. This action undoes the automatic selection of the entire word, and enables the user to precisely select part or all of the word.
When AutoWordSelection is disabled, a selection is not automatically expanded to include entire words; in this case precise selections are always determined manually.
