    User control referencing

    Hi all

    I have a user control - mycontrol.ascx with various controls within it.
    mycontrol.ascx is utilised in myPage.aspx

    I have a class (class1) to carry out various functions, subs etc.
    How do I go about setting the properties of the controls within
    mycontrol.ascx directly from class1

    Ideally what i'd like to do is various control property settings in class1
    when the myPage.aspx page load event fires - but for various reasons I don't
    want this done in the code behind of myPage.aspx or myControl.ascx -
    (myControl.ascx will be utilised across the site and the various controls
    within it will need their properties set depending on certain conditions that
    may arise)

    This sort of control referencing was very easy in access adp but I'm a bit
    bit lost here!!

    Any pointers - vb.net (if possible)

    Thanks

      A user control is just a class, so if u want to set its properties from
      another class, simply send a reference to it, to that class and make sure it
      exposes its controls as public properties..... or design some interface to
      allow this to be done.

      Better yet though i would go the other way. Send a class with the property
      values to the User Control and allow the usercontrol to set its own
      properties. Even if you have to design a third class to act as a property
      container i would still do it this way. Much cleaner.

          Thanks again Richard

          Found exactly what I needed to know at MSDN specifically at:

          UserControl Class (System.Web.UI)
          http://msdn.microsoft.com/en-us/library/system.web.ui.usercontrol.aspx
          Represents an .ascx file, also known as a user control, requested from a server that hosts an ASP.NET Web application. The file must be called from a Web Forms page or a parser error will occur.


          Its all very clear now!
