Login control and redirect depends on ROLE

Hi experts

How can i redirect user depends on role he belong?

        If (Membership.ValidateUser(Login1.UserName, Login1.Password)) Then
            Dim r() As String = Roles.GetRolesForUser(Login1.UserName)
            For i As Byte = 0 To r.Length
                Select Case r(i).ToUpper
                    Case "ABC"
                    Case "DEF"
                    Case "GHI"
                    Case "JKL"
                End Select
        End If

the code works but i cannot redirect the user, it's like web.config is missing something :

  <authentication mode="Forms">
   <forms name=".COOK" />
  <sessionState mode="InProc" cookieless="false" timeout="30"></sessionState>  
            <roleManager enabled="true">
    <remove name="AspNetSqlRoleProvider" />
    <add connectionStringName="SMS_ManConnectionString" applicationName="/"
     name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <remove name="AspNetSqlMembershipProvider" />
    <add connectionStringName="SMS_ManConnectionString" enablePasswordRetrieval="true"
     enablePasswordReset="true" requiresQuestionAndAnswer="false"
     applicationName="/" requiresUniqueEmail="true" passwordFormat="Encrypted"
     maxInvalidPasswordAttempts="5" minRequiredPasswordLength="1"
     minRequiredNonalphanumericCharacters="0" name="AspNetSqlMembershipProvider"
     type="System.Web.Security.SqlMembershipProvider, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

You should use role based authentication. see the following link

in fact the validation of user/pwd is correct, but i cannot redirect user to any page
it's like there is something wrong in the web.config file
