Solution 1

Add a class which hold all your enumerations (if more)

Add enum as below:

C#

public enum Gender
   {
       male = 1,
       female = 2,
       transgender = 3
   }

In C# code, bind it as below:

C#

foreach (var gen in typeof(Gender).GetFields())
            {
                if (gen.FieldType == typeof(Gender))
                    DropDownList1.Items.Add(new ListItem { Text = gen.Name, Value = gen.GetRawConstantValue().ToString() });
            }

Thanks,
Prashant

Any specific Reason for the Enum. Because that can be String,int or Collection datatype.

Thats the implementation choice. However if collection is known and static ( we are sure that gender collection will have these static entries), should go with enum. No need to add database calls and other impplementation. Reduce db call as much as possible. Make sense?

No I mean only for creating Object no db relation....
Enum,int ,string,collections,Class object these are some choices for that synario .... then which one i need to implement... Enum may be change ex("Select Category","Other")

that is just an example....

so what is the best way to using those problems.

i know that enum not change frequently but may be change. so.....

There is one more case if i want to select default female then how can i do it by using enum.

Choice would be depend on what type of data you are binding. Without looking at that, hard to make decision. Generally we should use collection if data is volatile and stored in database.

Making default is dropdownlists property and not of enum. you can use dropdownlist.items[0].selected=true property by selecting any item of choice.

In Controller

public ActionResult SelectCountry() {

     List<selectlistitem> items = new List<selectlistitem>();

     items.Add(new SelectListItem { Text = "India", Value = "0",Selected = true});

     items.Add(new SelectListItem { Text = "Nepal", Value = "1" });

   

     ViewBag.Country = items;

     return View();

 }
</selectlistitem></selectlistitem>

In View

@Html.DropDownList("Country")

For Your Application You can Use Like

public List<selectlistitem> Gender
{
get
{
List<selectlistitem> items = new List<selectlistitem>();

items.Add(new SelectListItem { Text = "Male", Value = "2",Selected = true});

items.Add(new SelectListItem { Text = "Female", Value = "2" });

return items;

}
}

Its May Suit for you !

Thanks
