Hi ,
I have to populate **distinct** company name in Dropdownlistfor from

@model IEnumerable<zykod.data.models.cutilitymodel>
I tried the following way. Nothing is working. Your help is appreciated.

1. @Html.DropDownListFor(Model.Select(i => i.CompanyName).Distinct().ToList(), new List<SelectListItem>(), new { @class = "input-large form-control" })

2. @Html.DropDownList("CompanyName", new SelectList(Model).Distinct())

3. @Html.DropDownListFor(model => model.CompanyName, new List<SelectListItem>(), new { @class = "input-large form-control" })

Thanks
Karthey

Try something like this:

C#

@Html.DropDownListFor(model => model.CompanyName, new SelectList(Model.Select(i => i.CompanyName).Distinct()), new { @class = "input-large form-control" })
