The functionality is identical in all three samples, differing only in the nature of the underlying data: user object collections (LiveLinqToObjects), ADO.NET DataSet (LiveLinqDataSet) or XML (LiveLinqToXml).</p> <p>To see live views in action, you can try, for example:</p> <ul> <li>Change the <b>ShipCity</b> value from "London" to "Colchester" or vice versa in any of the two grids and leave the current row (to commit the change). Observe that the value in the other grid changes accordingly.</li> </ul> <ul> <li>Change the <b>ShipCity</b> value to any string other than "London" and "Colchester" in any of the two grids. Observe that the row disappears from both grids.</li> </ul> <p>See also the Live views sample application (LiveLinqIssueTracker) for more advanced functionality.</p> <p><strong>LiveViewsObjects</strong></p> <p>This sample demonstrates basic live view functionality for views based on user-defined object collections (LiveLinq to Objects).</p> <p><strong>LiveViewsDataSet</strong></p> <p>This sample demonstrates basic live view functionality for views based on ADO.NET DataSet (LiveLinq to DataSet). This sample uses a typed data set, but untyped data sets can be used as well, as shown in the LiveLinqToDataSet sample.</p> <p><strong>LiveViewsXml</strong></p> <p>This sample demonstrates basic live view functionality for views based on XML (LiveLinq to XML).</p> <p> </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.
