    <p>I googled a lot of times but don't have any userful link for my solution. I have AllwSorting="true" and OnSort function. Today I post this question, thanks for all your help. This is my ASCX:</p> <pre><code>&lt;asp:GridView ID="gvwCus" runat="server" CssClass="gridview" AlternatingRowStyle-CssClass="even" AutoGenerateColumns="false" GridLines="Vertical" AllowPaging="false" OnRowCommand="RowCommand" AllowSorting="true" OnSorting="gvwCus_OnSorting"&gt; &lt;Columns&gt; &lt;asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" HeaderStyle-Width="4%"&gt; &lt;HeaderTemplate&gt;STT&lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblId" runat="server" Text="&lt;%#Container.DataItemIndex + 1%&gt;"&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:BoundField HeaderStyle-Width="12%" DataField="field1" HeaderText="Field1_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/&gt; &lt;asp:BoundField HeaderStyle-Width="30%" DataField="field2" HeaderText="Field2_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/&gt; &lt;asp:BoundField HeaderStyle-Width="31%" DataField="field3" HeaderText="Field3_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"/&gt; &lt;asp:BoundField HeaderStyle-Width="20%" DataField="field4" HeaderText="Field4_Header" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center" /&gt; &lt;asp:CommandField HeaderStyle-Width="2%" ButtonType="Image" SelectImageUrl="~/Images/detail.png" ShowSelectButton="true" /&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p>And my code behind: ASCX.CS, I have gvwCus_OnSorting function for Sort event, but don't have any event handled when I click on the header of gridview.</p> <pre><code>protected void gvwCus_OnSorting(object sender, GridViewSortEventArgs e) { DataBind(e); } private void DataBind(GridViewSortEventArgs eventArgs) { var dataOracle = new DataOracle(); var data = dataOracle.GetDataTable(); if(eventArgs != null) { data.DefaultView.Sort = eventArgs.SortExpression + " " + GetSortDirection(eventArgs.SortExpression); } gvwCustom.DataSource = data; gvwCustom.DataBind(); } private string GetSortDirection(string column) { string sortDirection = "DESC"; string sortExpression = ViewState["SortExpression"] as string; if (sortExpression != null) { if (sortExpression == column) { string lastDirection = ViewState["SortDirection"] as string; if ((lastDirection != null) &amp;&amp; (lastDirection == "DESC")) { sortDirection = "ASC"; } } } ViewState["SortDirection"] = sortDirection; ViewState["SortExpression"] = column; return sortDirection; } </code></pre> <p>Thanks!!</p>

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.
