In ASP.NET MVC 2, I'd like to write a very simple dropdown list which gives static options. For example I'd like to provide choices between "Red", "Blue", and "Green".

html.dropdownlistfor
With "Please select one Item"
@Html.DropDownListFor(model => model.ContentManagement_Send_Section,
new List<SelectListItem> { new SelectListItem { Value = "0", Text = "Plese Select one Item" } }
.Concat(db.NameOfPaperSections.Select(x => new SelectListItem { Text = x.NameOfPaperSection, Value = x.PaperSectionID.ToString() })),
new { @class = "myselect" })

Good luck friends.
Or if it's from a database context you can use
@Html.DropDownListFor(model => model.MyOption, db.MyOptions.Select(x => new SelectListItem { Text = x.Name, Value = x.Id.ToString() }))
Hi here is how i did it in one Project :
@Html.DropDownListFor(model => model.MyOption,
new List<SelectListItem> {
new SelectListItem { Value = "0" , Text = "Option A" },
new SelectListItem { Value = "1" , Text = "Option B" },
new SelectListItem { Value = "2" , Text = "Option C" }
},
new { @class="myselect"})
I hope it helps Somebody. Thanks
<%:
Html.DropDownListFor(
model => model.Color,
new SelectList(
new List<Object>{
new { value = 0 , text = "Red" },
new { value = 1 , text = "Blue" },
new { value = 2 , text = "Green"}
},
"value",
"text",
Model.Color
)
)
%>
or you can write no classes, put something like this directly to the view.
@using (Html.BeginForm()) {
<p>Do you like pizza?
@Html.DropDownListFor(x => x.likesPizza, new[] {
new SelectListItem() {Text = "Yes", Value = bool.TrueString},
new SelectListItem() {Text = "No", Value = bool.FalseString}
}, "Choose an option")
</p>
<input type = "submit" value = "Submit my answer" />
}
I think this answer is similar to Berat's, in that you put all the code for your DropDownList directly in the view. But I think this is an efficient way of creating a y/n (boolean) drop down list, so I wanted to share it.
Some notes for beginners:
Hope this helps someone,
Avoid of lot of fat fingering by starting with a Dictionary in the Model
namespace EzPL8.Models
{
public class MyEggs
{
public Dictionary<int, string> Egg { get; set; }
public MyEggs()
{
Egg = new Dictionary<int, string>()
{
{ 0, "No Preference"},
{ 1, "I hate eggs"},
{ 2, "Over Easy"},
{ 3, "Sunny Side Up"},
{ 4, "Scrambled"},
{ 5, "Hard Boiled"},
{ 6, "Eggs Benedict"}
};
}
}
In the View convert it to a list for display
@Html.DropDownListFor(m => m.Egg.Keys,
new SelectList(
Model.Egg,
"Key",
"Value"))
