Accessing data from a BoundField of Gridview
<p>I have a GridView like this</p>

<pre><code>&lt;asp:GridView ID="gv_FilesList" runat="server" AutoGenerateColumns="false" onrowcommand="gv_FilesList_RowCommand"&gt;
  &lt;Columns&gt;
    &lt;asp:BoundField DataField="f_Id" Visible="false" HeaderText="File Name" /&gt;
  &lt;/Columns&gt;  
  &lt;Columns&gt;
   &lt;asp:BoundField DataField="f_Name" HeaderText="File Name" /&gt;
  &lt;/Columns&gt;                                      
  &lt;Columns&gt;
    &lt;asp:ButtonField ButtonType="Link" Text="Download" CommandName="DownloadFile" HeaderText="Download" /&gt;
  &lt;/Columns&gt;
&lt;/asp:GridView&gt;
</code></pre>

<p>Now when I click on the download Button, how can I get the corresponding f_Id in order to get the related data from Database. </p>
