<asp:dropdownlist id="DDLTitle" OnSelectedIndexChanged="Select" style="Z-INDEX: -1" runat="server"
Width="110" AutoPostBack="true"></asp:dropdownlist>
</div>
<asp:textbox id="txtTitle" style="Z-INDEX: 102; LEFT: 47px; POSITION: absolute; TOP: 26px" runat="server"
Font-Size="10" Width="111" maxLength="50" Height="22"></asp:textbox>
