In this example, I would like to tell you that how to bind a Generic List to DropDownList server control in asp.net page. Let’s start

Open your Visual Studio 2008/2010 and create a website, I will consider here that you know how to create a website in Visual Studio 2008/2010.

First I have created a DDList class in Default.aspx.cs/vb page to bind DropDownList server control.

C#

   public class DDList
   {
       public string Item { get; set; }
       public string value { get; set; }
   }

VB.NET

   Public Class DDList
       Public Property Item() As String
           Get
               Return m_Item
           End Get
           Set(ByVal value As String)
               m_Item = value
           End Set
       End Property
       Private m_Item As String
       Public Property value() As String
           Get
               Return m_value
           End Get
           Set(ByVal value As String)
               m_value = value
           End Set
       End Property
       Private m_value As String
   End Class

Now,I  have created a function which will return a List into DropdownList as shown below.

C#

   private List<DDList> fillDropDownList()
   {
       return new List<DDList>(){
       new DDList{ Item="SELECT", value="0"},
       new DDList{ Item="Aamir Hasan", value="1"},
       new DDList{ Item="Fasial Hameed", value="2"},
       new DDList{ Item="Saba Khan", value="3"}
       };
   }

VB.NET

   Private Function fillDropDownList() As List(Of DDList)
    Return New List(Of DDList)() With { _
        New DDList() With { _
            .Item = "SELECT", _
            .value = "0" _
        }, _
        New DDList() With { _
            .Item = "Aamir Hasan", _
            .value = "1" _
        }, _
        New DDList() With { _
            .Item = "Fasial Hameed", _
            .value = "2" _
        }, _
        New DDList() With { _
            .Item = "Saba Khan", _
            .value = "3" _
        } _
    }
   End Function

Drag and drop DropDownList server control from toolbar into your Default.aspx page as given below.

 <asp:DropDownList ID="DropDownList1" runat="server" />
