Asp.net 2.0 Roles DropDownList Control in C#

Translation of this post to french at :
http://s4n44.blogspot.com/2008/02/aspnet-20-dropdownlist-de-rles-enc.html

This is a user control, which encapsulates a DropDownList, an ObjectDataSource and custom, simplified roles class. The user control will connect automatically (of course), with the aspnetdb database pointed to in the web.config
for vb.net users, here's a nice converter provided by Telerik (http://www.telerik.com ) :

Here's the code for the user control :

<%@ Control Language="C#" AutoEventWireup="true" CodeFile=" ddlRoles.ascx.cs" Inherits="RoleControl" %>
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sourceRoles" DataTextField="RoleName"
    DataValueField="RoleName" Width="185px">
</asp:DropDownList>
<asp:ObjectDataSource ID="sourceRoles" runat="server" SelectMethod="GetRoles"
    TypeName="CustomRoles"></asp:ObjectDataSource>

Code behind for the user control:

using System;

public partial class RoleControl : System.Web.UI.UserControl
{
    public String SelectedValue
    {
        get { return this.DropDownList1.SelectedValue; }
        set { this.DropDownList1.SelectedValue = value; }
    }
}

The object datasource uses the class below :

using System;
using System.Web.Security;
using System.Collections.Generic;

public class CustomRoles
{
    private string mRoleName;

    public string RoleName
    {
        get { return mRoleName; }
        set { mRoleName = value; }
    }

    /// <summary>
    /// this function, loops through all roles in the database, and builds 
    /// a collection of CustomRoles instances into a generic list of CustomRoles
    /// then we return the list as the source for the dropdown. 
    /// The RoleName property is used to bind the datavaluefield and datatextfield
    /// in the dropdownlist
    /// </summary>
    /// <returns></returns>
    public List<CustomRoles> GetRoles()
    {
        //getroles
        string[] roleslist = Roles.GetAllRoles();

        int i = 0;
        //instance of customroles
        CustomRoles br;

        //create the list (or collection of CustomRoles instances)
        List<CustomRoles> lstbr = new List<CustomRoles>();

        //fill the list by looping through the array of strings
        foreach (string brole in roleslist)
        {
            br = new CustomRoles();
            br.RoleName = brole;
            lstbr.Add(br);
        }
        
        return lstbr;

    }

}
