Easy workaround. In your query, do a UNION with a "--please select---' clause.

For e.g.

C#

select id, name from mytable
UNION
select 0, '--please select---'

XML

<asp:DropDownList ID="DropDownList1" runat="server">
    <asp:ListItem>--Select This---</asp:ListItem>
</asp:DropDownList>

use the same as a list item and bind other value on the top of that.

Thanks,

try this :

private void FillDropDownList()
    {
        DataSet ds = new DataSet();
        SqlDataAdapter myda = new SqlDataAdapter("Select field  FROM tablename",con object);
        myda.Fill(ds);
        drop1.DataSource = ds;
        drop1.DataValueField = "field";
        drop1.DataBind();
        drop1.Items.Insert(0, new ListItem("--Please Select", "0"));
    }

and on Page Load

C#

if(!ispostback)
{
  FillDropDownList();
}

Thanks.....
