ASP.NET How to raise load event on previous page with cross page postbacks

Question

I'm working on a wizard-like set of page, and I'm relying on cross page postbacks to navigate between them.

I need to be able to trigger the Load event on the previous page in order to save the form data for the page.

I've been told that for situations of this sort all I had to do is access the PreviousPage property in the destination page and this would trigger the load event of the previous page but for some reason this doesn't seem to be working.

Is there anything else I can do to explicitly trigger the load event on the previouspage if the PreviousPage property is not null?

Thanks for your help,

Yong

Answer 1

Have you considered moving whatever persistence logic you're doing in the load of the Previous Page into a method on the page?

That way you can just hit:

if(PreviousPage != null)
   PreviousPage.DoThatSavingThing();

Obviously you'd need to type it to get the specific methods you add unless you added those to all pages.
