How do you bind an Enum to a DropDownList control in ASP NET

0 votes

Let's say I have the following simple enum:

enum Response
{
    Yes = 1,
    No = 2,
    Maybe = 3
}

How can I bind this enum to a DropDownList control so that the descriptions are displayed in the list as well as retrieve the associated numeric value (1,2,3) once an option has been selected?

Hello @kartik,

I probably wouldn't bind the data as it's an enum, and it won't change after compile time.

Better just to iterate through the enum:

Dim itemValues As Array = System.Enum.GetValues(GetType(Response))
Dim itemNames As Array = System.Enum.GetNames(GetType(Response))

For i As Integer = 0 To itemNames.Length - 1
    Dim item As New ListItem(itemNames(i), itemValues(i))
    dropdownlist.Items.Add(item)
Next

Or the same in C#

Array itemValues = System.Enum.GetValues(typeof(Response));
Array itemNames = System.Enum.GetNames(typeof(Response));

for (int i = 0; i <= itemNames.Length - 1 ; i++) {
    ListItem item = new ListItem(itemNames[i], itemValues[i]);
    dropdownlist.Items.Add(item);
}

Hope it helps!!

Thank You!!
