Hi there,

I have problems in dealing AJAX (Im implementing a text box with the calendar extender) in dotnetnuke framework. I have followed the instructions online and write the following codes:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            If Not IsPostBack Then
                If DotNetNuke.Framework.AJAX.IsInstalled Then
                    DotNetNuke.Framework.AJAX.RegisterScriptManager()
               End If
            End If

However, when I load the dotnetnuke, similar error of only one scriptmanager can be loaded appeared. May I know how can I go about only allowing 1 scriptmanager to load? I have tried replacing the IsInstalled with IsEnabled and it doesn't work as well..

Thanks!
