Help with custom registration page.

If your assembly is placed in the GAC it will run with full trust. No additional trust is required in the web.config file. When I get stuck in these type of situations I typically start removing all of my dependencies from my .aspx files. I would begin by removing all controls from the page except for a hello messages. Finally, you can try Inheriting from the LayoutsPageBase class which is the base class for most SharePoint layouts pages.

Depending on what you are trying to accomplish it may be easier to modify the out-of-the-box register.aspx page. In this page you can override the OnRegistering and OnRegistered methods to perform actions. The samples below validate the length of the user name and modify profile properties associated with a user.

<script runat="server"> 

/// <summary>
/// Define an empty registration event
/// </summary>
/// <param></param>
protected override void OnRegistering(RegistrationEventProperties eventProperties)
{

      if(eventProperties.UserName.Length < 8)
      {
            eventProperties.ErrorMessage = "You user name must be 8 characters.";
            eventProperties.Cancel = true;
      }
}

/// <summary>
/// Define an empty registration event
/// </summary>
/// <param></param>
protected override void OnRegistered(RegistrationEventProperties eventProperties)
{

      // Update internal name
      eventProperties.Profile["InternalName"] = String.Format(
            "{0} {1}",
            eventProperties.Profile["FirstName"],
            eventProperties.Profile["LastName"]);

      // Save profile
      eventProperties.Profile.Save();
}
</script>
