Question

I want Add “Select Activity” values as first values of HTML dropdown, but when I add it is showing as last record in Drop down.

I want to show Default value as “Select Activity” in drop down.

I am using ASP.NET MVC3, code:

public SelectList GetSubContractorechniciansList(String subContractorId)
{
    var s1 = GetSubContractorechnicians(subContractorId);
    var result = s1.ToList().Select(d => new
    {
        Key = d.TECH_NUMBER,
        Value = d.EMPLOYEE_TECH_NAME.ToString()
    }).Distinct().ToDictionary(mc => mc.Key, mc => mc.Value);
    result.Add("Select Activity", "Select Activity");
    var selectItems = new SelectList(result, "Key", "Value");            
    return selectItems;
}

You do this when rendering the dropdown in your view:

@Html.DropDownListFor(x => x.SomeModelProperty, Model.Items, "Select Activity")

or if against all good practices you don’t use a view model and rely on weakly typed ViewBag and helpers:

@Html.DropDownList("ddlName", (IEnumerable<SelectListItem>)ViewBag.Items, "Select Activity")
