Hello Mark,
Could you please look into
http://msdn.microsoft.com/library/en-us/cpgenref/html/cpconimplementsdirective.asp?
frame=true?
It lists code samples demonstrating a user control that includes an @ Implements directive to access the properties and
methods of the IPostBackEventHandler interface.
Hope that helps.
Best regards,

!Teemu,
!
! I have tried to derive the user controls from
!IPostBackEventHandler and IPostBackDataHandler and
!implement the interfaces, but the implementations are
!never called so it seems that those interfaces won't
!wonrk on user controls. Basically, I have a web form
!AddNewUser.aspx and a couple of user controls that handle
!sending e-mail notifications/reminders
!(EmailReminder.ascx and EmailNotification.ascx) and a
!date/time picker user control (DateTimePicker.ascx).
!When the user clicks the "Add" button to add the new
!user, the EmailReminder.ascx and EmailNotification.ascx
!have to run code to send and schedule the e-mails. I put
!the code in a user control because I am looking to reuse
!it on a bunch of pages (AddNewUser.aspx is just the first)
!and the UI doesn't lend itself to being a server
!control. I could give the user controls public methods
!OnSubmit() and have the Page's OnSubmit event handler
!explicitly call [UserControl].OnSubmit(). This might be
!easier than setting up an event in the Page and event
!handlers in the user control, but it would better for the
!user controls to somehow register their own postback
!handlers so the Page that contains them doesn't have to
!do anything. If this still doesn't make sense or you
!would like more information please let me know. Thanks
!for your help!
