You did not say where this control is in your form.

If this error is the result of another control being inside the GridView control, just like mine, this can also help you:

An xxx control of type 'LinkButton' must be placed inside the form tag using runat = server

The error is a "txtTo" of type "TextBox", which should be placed inside the form tag using the runat = server.

ERROR is a code.

      <tr>
          <td class="style1">
                <strong>To </strong>
            </td>
            <td class="style2">
                <strong>: </strong>
            </td>
            <td class="style6">
                &nbsp;
                <asp:TextBox ID="txtTo" runat="server" Width="475px"></asp:TextBox>
            </td>
            <td></td>
