This tutorial will explain how to bind List<T> to the listbox/dropdown list. Following are some simple steps to bind your listbox/dropdown list to List<T>.

Step 1

Create a List<T> in you code behind file i.e. .CS file. Following code shows how the List<T> of string is created. Months is a List<String> which stores a list of months in a year.

///Creating List of string for months.
    public static List<string> Months = new List<string> { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };

//Binding list of string to listbox
        lst.DataSource = Months;
        lst.DataBind();

        //Binding list of string to dropdown list
        drp.DataSource = Months;
