    <p>Why don't you simply add a Label before the Donwload-Button in the ItemTemplate? You could set the Label's Text in RowDataBound(gridView2_DataBound).</p> <p>Edit: to show the header columns of the nested gridview in the header of the outer gridview, you could set <code>ShowHeader="false"</code> in the inner grid and use a HeaderTemplate with two labels for "Software Titles" and "Download here" and appropriate CSS-Styles to fit to the inner grid.</p> <p><strong>Edit</strong>: </p> <p>Here is a working test-page. Pick the parts you didn't understand:</p> <p><strong>aspx</strong>:</p> <pre><code> &lt;asp:GridView ID="GrdTransaction" runat="server" OnRowDataBound="GrdTransaction_RowDataBound" AutoGenerateColumns="false"&gt; &lt;Columns&gt; &lt;asp:BoundField DataField="DateOfTransaction" HeaderText="Date Of Transaction" SortExpression="DateOfTransaction" /&gt; &lt;asp:TemplateField&gt; &lt;HeaderTemplate&gt; &lt;table width="100%" cellspacing="0" cellpadding="0" border="0"&gt; &lt;tr&gt; &lt;td&gt;&lt;asp:Label ID="LblFileNameHeader" Text="File-Name" runat="server" /&gt;&lt;/td&gt;&lt;td&gt;&lt;asp:Label ID="LblDownloadHeader" Text="Download file" runat="server" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;asp:GridView ID="GrdDocument" runat="server" ShowHeader="false" GridLines="None" AutoGenerateColumns="false" OnRowCommand="GrdDocument_RowCommand" OnRowDataBound="GrdDocument_RowDataBound"&gt; &lt;Columns&gt; &lt;asp:TemplateField ItemStyle-HorizontalAlign="Center" ItemStyle-Width="100px"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="LblFileName" Text='&lt;%# Eval("Doc")%&gt;' runat="server" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField ItemStyle-HorizontalAlign="Center" ItemStyle-Width="100px"&gt; &lt;ItemTemplate&gt; &lt;asp:Button ID="BtnDownload" runat="server" CommandArgument='&lt;%# Eval("Doc")%&gt;' CommandName="Download" Text="Download" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p><strong>Codebehind</strong>(converted from vb.net to c#):</p> <pre><code>public class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { this.GrdTransaction.DataSource = GetOuterGridSource(); this.GrdTransaction.DataBind(); } } private DataTable GetOuterGridSource() { DataTable tbl = new DataTable(); tbl.Columns.Add(new DataColumn("ID", typeof(Int32))); tbl.Columns.Add(new DataColumn("DateOfTransaction", typeof(DateTime))); DataRow row = tbl.NewRow(); row["ID"] = 1; row["DateOfTransaction"] = System.DateTime.Now; tbl.Rows.Add(row); row = tbl.NewRow(); row["ID"] = 2; row["DateOfTransaction"] = System.DateTime.Now; tbl.Rows.Add(row); row = tbl.NewRow(); row["ID"] = 2; row["DateOfTransaction"] = System.DateTime.Now; tbl.Rows.Add(row); return tbl; } private DataTable GetNestedGridSource() { DataTable tbl = new DataTable(); tbl.Columns.Add(new DataColumn("ID", typeof(Int32))); tbl.Columns.Add(new DataColumn("Doc", typeof(string))); DataRow row = tbl.NewRow(); row["ID"] = 1; row["Doc"] = "Smart Defrag"; tbl.Rows.Add(row); row = tbl.NewRow(); row["ID"] = 2; row["Doc"] = "Visio Viewer"; tbl.Rows.Add(row); row = tbl.NewRow(); row["ID"] = 2; row["Doc"] = "Rapid Typing"; tbl.Rows.Add(row); return tbl; } protected void GrdTransaction_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { dynamic row = ((DataRowView)e.Row.DataItem).Row; dynamic GrdDocument = (GridView)e.Row.FindControl("GrdDocument"); GrdDocument.DataSource = GetNestedGridSource(); GrdDocument.DataBind(); GrdDocument.RowCommand += GrdDocument_RowCommand; } } protected void GrdDocument_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { dynamic row = ((DataRowView)e.Row.DataItem).Row; dynamic LblFileName = (Label)e.Row.FindControl("LblFileName"); LblFileName.Text = row("Doc").ToString; } } protected void GrdDocument_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e) { if (e.CommandName == "Download") { dynamic docName = e.CommandArgument.ToString(); } } public WebForm1() { Load += Page_Load; } } </code></pre> <p>I have set the LblFileName's Text poperty in <code>GrdDocument_RowDataBound</code>. That is redundant because i've always used <code>eval</code> on the aspx-page. I wanted to show both ways for the sake of completeness.</p> <p>This is result:</p> <p><img src="https://i.stack.imgur.com/Y7DVf.jpg" alt="enter image description here"></p>

    1. CO@Tim I have one more question, if you want i can post it separately, depends on your decision but it is kind of related. If you look at the output screenshot (EDITED !!). http://postimage.org/image/1c9ru8q84/ There is a last column in the Parent grid view which doesn't have header. Can I have header set for the parent grid view as shown in the intended output screenshot

    3. CO@Tim ur idea of header columns worked but i have been struggling with the RowDataBound(gridView2_DataBound) method. I cannot make sense of it. I create gridview2 on gridview1 rowdatabound event. And more over I filter the data in gridview2 based on each gridview1 specific row's invoice number (again please refer to the screenshot). How can i create label and bind it to the datasource

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
