Code so far! Yes its not working....

 private void populateDropdowns()
        {

            using (FoodEntities dbcontext = new FoodEntities())
            {
                        ddlDiet.DataSource = (from d in dbcontext.Menus
                                             select new { d.MenuID , d.Menu1 }).ToList();
             
               ddlDiet.DataValueField = "MenuID";
               ddlDiet.DataTextField = ("Please select Menu","Menu1");
               ddlDiet.DataBind();

Hi brucey,

Hi folks, how do you set a default text value"Please select Menu Type" when pre populating a dropdown from code?

As far as I know, you could use jQuery append function add html elements to pre populating a dropdown.

More details, you could refer to follow codes:

<head runat="server">
    <script src="jquery-1.7.1.js"></script>
    <title></title>
    <script>
        $(function () {
            $("#DropDownList1").append($('<option></option>').val('Menu1').html('Please select Menu'));
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:DropDownList ID="DropDownList1" runat="server">

        </asp:DropDownList>

    </div>
    </form>
</body>

Best Regards,

Brando
