Hi group,

I try to develop a gallery control, that uses templates for displaying. 
Everything should (as I can say) be correct, but "InstantiateIn" does not 
get the right data from my container-class.

The source looks like this, could someone please help me, I have no idea 
what I did wrong!
(Note: When I change "Container.Url" to "Container.XXX", the compiler 
recognizes, that XXX is not a member of ImageTemplateContainer.)

Thank you
Thomas

  public class ImageTemplateContainer : Control, INamingContainer
  {
    private String m_strUrl;
    public String Url
    {
      get
      {
        return m_strUrl;
      }
    }

    public ImageTemplateContainer(String NavUrl)
    {
      this.m_strUrl = NavUrl;
    }
  }
