i have did this

<form id="form1" runat="server">

<asp:DropDownList ID="reservation1" CssClass="tel" runat="server">
<asp:ListItem Value="0">--Select--
<asp:ListItem Value="1">General
<asp:ListItem Value="2">SC/ST
<asp:ListItem Value="3">Others

<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click2" />

</form>

protected void Button1_Click2(object sender, EventArgs e)
{
reservation1.SelectedIndex = 0;
}

it works perfect..
