Dear All,

I have dropdownlist & i am binding my datatable values to it.

C#

ddlMName.DataSource = objDS.Tables[0];
ddlMName.DataTextField = "MenuName";
ddlMName.DataValueField = "MenuID";
ddlMName.DataBind();
with addition of this i need to bind the following value to it
ddlMName.Items.Add(new ListItem("<<Select One>>", "-1"));

<<select one>> should display in dropdownlist at first & then datatable values.

How can i do this?

Hi ,
try this one ,
You have to set AppendDataBoundItems = True

ASP.NET

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="True">
    <asp:ListItem Value="-1">--select on --</asp:ListItem>
</asp:DropDownList>

Best Regards
