aspx code
---------
<asp:DropDownList ID="ddlSearch" runat="server" Width="100px" AutoPostBack="True"
onselectedindexchanged="ddlSearch_SelectedIndexChanged">


C# Code

protected void dropdown_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlSelection.SelectedValue == "0")
{
txtAccountno.Visible = true;

}
