    <p>I would recommend that you look at this post and reverse the ascending / descending flag logic.</p> <p><a href="https://stackoverflow.com/questions/250037/gridview-sorting-sortdirection-always-ascending">GridView sorting: SortDirection always Ascending</a></p> <p>Your ASPX page will have a gridview like this (pay specific attention to the OnSorting part):</p> <pre><code>&lt;asp:GridView ID="grdHeader" AllowSorting="true" AllowPaging="false" AutoGenerateColumns="false" Width="780" runat="server" OnSorting="grdHeader_OnSorting" EnableViewState="true"&gt; &lt;Columns&gt; &lt;asp:BoundField DataField="Entitycode" HeaderText="Entity" SortExpression="Entitycode" /&gt; &lt;asp:BoundField DataField="Statusname" HeaderText="Status" SortExpression="Statusname" /&gt; &lt;asp:BoundField DataField="Username" HeaderText="User" SortExpression="Username" /&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p>Your CodeBehind (aspx.cs) will then need to implement the method grdHeader_OnSorting. The variables in GridViewSortEventArgs will tell you which direction the user asked to sort. In your case you would then do the opposite...such as:</p> <pre><code>protected void grdHeader_OnSorting(object sender, GridViewSortEventArgs e) { List&lt;V_ReportPeriodStatusEntity&gt; items = GetPeriodStatusesForScreenSelection(); SortDirection dir = e.SortDirection == SortDirection.Ascending ? SortDirection.Descending : SortDirection.Ascending; items.Sort(new Helpers.GenericComparer&lt;V_ReportPeriodStatusEntity&gt;(e.SortExpression, dir)); grdHeader.DataSource = items; grdHeader.DataBind(); } </code></pre> <p>Here the items.Sort method is doing all the sorting...all you are doing is taking that sorted result and assigning it back to your datasource.</p> <p>If you want more information on the concept of how to sort a GridView, I'd recommend looking at this example on MSDN: <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.sort.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.sort.aspx</a></p> <p>Let me know if there is anything else I can do to clarify.</p>

    1. COYou see my problem is the following. I did read through that post before I posted this, but there are 6 or 7 answer, all voted up on and differs from each other. I'm still very new to programming and ASP.NET and I don't really understand all that code. I can't believe that something that is suppose to be so simple is so complicated(complicated being used out of my expertise vocabulary)...Any more specific suggestions...Ive literally spend the whole day trying to solve this problem, but everywhere I go people's code differs significantly from each other. One says this, another says that.

    3. COyes thank you. I implemented it like you recommended, but I get the 'missing using directive or assembly reference' error for the following lines: V_ReportPeriodStatusEntity; GetPeriodStatusesForScreenSelection(); Helpers.Any suggestions?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
