Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public class RoleServiceManager

The RoleServiceManager class corresponds to the RoleService property of the ScriptManager or ScriptManagerProxy control.

The role Web service is used by AJAX-enabled applications to retrieve role information for the current authenticated user by using an asynchronous Web service call. You can use RoleServiceManager to provide the path of an alternative implementation of the role Web service instead of using the built-in Web service.

To use the role service in your application, you must enable it in the configuration file and declare it in the page. If you use the built-in role Web service, you have to enable it, but you do not have to explicitly declare the role service manager in the page.

To create a custom role service, you must implement a Web service that has two methods: GetRolesForCurrentUser and IsCurrentUserInRole. These methods must have the same signature as the corresponding methods of the built-in role Web service.

The following example shows the basic class structure that must be implemented in a custom role Web service class.

<%@ WebService Language="C#" Class="MyRoleService" %>

using System.Web.Services;
using System.Web.Script.Services;

[ScriptService]
public class MyRoleService  : System.Web.Services.WebService 
{
    [WebMethod]
    public string[] GetRolesForCurrentUser()
    {
        //Place code here. 
        return null;
    }

    [WebMethod]
    public bool IsCurrentUserInRole(string role) 
    {
        //Place code here. 
      return false;
    }  
}

To use a custom role Web service, you can add the service declaratively in markup by putting a RoleService element inside the ScriptManager control, as shown in the following example.

<asp:ScriptManager ID="SM1" runat="server">
  <RoleService Path="MyRoleService.asmx" LoadRoles="true" />
</asp:ScriptManager>

You can also programmatically set the Path property to use a custom role Web service.
