<asp:DropDownList ID="ddlsendmail" runat="server" Width="250px" AutoPostBack="true"
    OnSelectedIndexChanged="ddlsendmail_SelectedIndexChanged" onchange="test();">
    <asp:ListItem>--select--</asp:ListItem>
    <asp:ListItem Value="Members">Members</asp:ListItem>
    <asp:ListItem Value="NonMembers">Non-Members</asp:ListItem>
    <asp:ListItem Value="Location">Location</asp:ListItem>
</asp:DropDownList>
when i choose Location, another one dropdown was bind with the values like Chennai (100), Mumbai (156),Banglore (132) etc.,
<tr id="tdsendmaillocation" runat="server" visible="false">
    <td>
        Location:
    </td>
    <td>
        <asp:DropDownList ID="ddlsendmaillocatiom" runat="server" Width="250px">
        </asp:DropDownList>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator2" SetFocusOnError="true" ValidationGroup="group"
