Hiding a cell with a Hidden Field
<p>In my GridView, I am using a Hidden Field to store some data that is not supposed to be seen by the user:</p>

<pre><code>                                    &lt;Columns&gt;
                                    &lt;asp:BoundField DataField="Название" HeaderText="Название" ItemStyle-Width="250px" HeaderStyle-Width="250px" /&gt;
                                    &lt;asp:BoundField DataField="RDName" HeaderText="РД" ItemStyle-Width="250px" HeaderStyle-Width="250px" /&gt;
                                    &lt;asp:TemplateField&gt;
                                        &lt;ItemTemplate&gt;
                                            &lt;asp:HiddenField ID="RD_ID" runat="server" Value='&lt;%# Eval("RD_ID") %&gt;' /&gt;
                                        &lt;/ItemTemplate&gt;
                                    &lt;/asp:TemplateField&gt;
                                &lt;/Columns&gt;
</code></pre>

<p>I have a problem with this. Though the data is not seen in the GridView, the additional empty cell is still there. Could you please tell me how I can hide it completely?
Thanks,
David</p>
