Asp.net mvc dropdown list using ViewBag

Question

My table in db have fields : Id,Organisation,Info.

I want make dropdowm list like that:

<select>
  <option value='Id there'>'Organisation there'</option>...

I'm try to do it, using ViewBag:

ViewBag.Organisations = db.Organisations.ToList(); // get all fields from table using dbContext

and in View:

@Html.DropDownList('I don`t know what i shoud write here, please help')

How i can build dropdown list?

Answer 1

I recommend you to define a ViewModel for your page with a OrganisationId property. Thus this value will be filled when selecting an entry of the organisations dropdown list.

@model BCO.Models.SelectOrganisationViewModel

@{
    ViewBag.Title = "OrganisationInfo";
}

<div>
    @Html.DropDownListFor(o => o.OrganisationId,
        new SelectList(ViewBag.Organisations, "Id", "Name"))
</div>

The SelectList itself expects

• the list to fill the DropDownList with
• the value ("Id")
• the text ("Name")

as parameters.
