    copied!<p>You need to enable sorting (<strong><a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.allowsorting.aspx" rel="nofollow noreferrer">AllowSorting</a></strong>) and handle the event <strong><a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.sorting.aspx" rel="nofollow noreferrer">OnSorting</a></strong>.</p> <p><strong><em>Note: The sample code uses C#, but the VB version should be similar.</em></strong></p> <p>Create your <strong>GridView</strong>:</p> <pre><code>&lt;asp:GridView ID="GridView1" runat="server" AllowSorting="True" OnSorting="GridView1_Sorting"&gt; &lt;/asp:GridView&gt; </code></pre> <p>Handle <strong>OnSorting</strong>:</p> <pre><code>protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) { GridView1.DataSource = GetObjects(e.SortDirection, e.SortExpression); GridView1.DataBind(); } </code></pre> <p><strong>GetObjects</strong> returns a sorted <code>List&lt;MyObject&gt;</code>. You have to create your own sorting logic here, one alternative could be using <a href="https://stackoverflow.com/questions/41244/dynamic-linq-orderby">Dynamic Linq</a>. If you choose that route, <strong>GetObjects</strong> could be defined like this: (there are better ways, but this is enough to show the theory)</p> <pre><code>private List&lt;MyObject&gt; GetObjects(SortDirection sd, string se) { // Have we generated data before? if (SimulatedDB == null) { // Create a sample DB SimulatedDB = new List&lt;MyObject&gt;(); var rnd = new Random(); for (int i = 0; i &lt; 20; i++) { var node = new MyObject(); node.Id = i; node.Name = String.Format("Name {0}", i); node.CreationDate = DateTime.Now.AddDays(rnd.Next(100)); node.Amount = (rnd.Next(1000) * rnd.NextDouble()); SimulatedDB.Add(node); } } // Return sorted list if (sd == SortDirection.Ascending) return SimulatedDB.AsQueryable&lt;MyObject&gt;().OrderBy&lt;MyObject&gt;(se).ToList(); else return SimulatedDB.AsQueryable&lt;MyObject&gt;().OrderByDescending&lt;MyObject&gt;(se).ToList(); } </code></pre> <p>Hope it helps.</p>
