Asp.net mvc dropdown list using ViewBag

Answer 1

You would need to create a SelectList in controller action using one of the constructors available and in view just pass it DropDownList method as parameter.

In Controller do this:

ViewBag.Organisations = new SelectList(db.Organisations.ToList(),"Id","Organisation");

in SelectList we need to specify which property to use as value and which to use as text in the option tag which we are specifying in last two parameters.

and then in View you would need to use it this way:

@Html.DropDownList("Organization",ViewBag.Organisations as SelectList)

Here first parameter would be used as name of select element and second one will be used to populate the option elements in the select

Following is the list of overloads available for Html.DropDownList :
