The ClientViewSource class is independent of GUI; it can be used in code with any of the GUI platforms (WPF, Silverlight, WinForms). It can be used completely separately from GUI, including in the view model layer of an MVVM application. At the same time, the <b>ClientViewSource</b> is the same object <b>C1DataSource</b> uses, so you can keep the ease of use characteristic of <b>C1DataSource</b> (but code-only, without visual designers). In fact, <b>C1DataSource</b> is just a collection of <b>ClientViewSource</b> objects plus visual designer support for them.</p> <p class="MsoBodyText" style="MARGIN-LEFT: 0.5in; TEXT-INDENT: -0.25in"><span style="FONT-FAMILY: Symbol">·<span style="FONT: 7pt 'Times New Roman'; font-size-adjust: none; font-stretch: normal"> </span></span> For the most complete control over your code, you can use the third, lowest level of the <b>EF DataSource</b> object mode: the <b>ClientView</b> class. If you prefer pure code, especially (but not only) using the MVVM pattern, this is the recommended level. It is still easy to program with, it is mostly based on LINQ which promotes a functional style of programming, intuitive and expressive.</p> <p class="MsoBodyText">The rest of this section is devoted to programming using the <b>ClientView</b> class.</p> <a name="seealsobookmark"></a> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p>Copyright (c) <script type="text/javascript"> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
