PreviousPage of MasterPage alway null4/22/2007 9:31:58 AM

0/0

Hello,

 

I want to access the PreviousPage property of a page in a masterpage, but even if it is a cross-page postback the value in the masterpage is always null, while in the inheriting page it is set correctly. Am i doing something wrong? Or is there a work around?

 

Thanks,

Jelmer Hoogendoorn

Hi Jelmer,

Are you setting the PreviousPage directive correctly in the destination page like:

<%@ PreviousPageType VirtualPath="~/FirstPage.aspx"  %>

Let me know if this does not work for you.

Hope this helps,

Vivek

I don't think the PreviousPageType directive is the solution. To answer your question, i don't set it because i don't know what the previous page will be. And as far as I understood is the previouspagetype directive only used to make the PreviousPage property of Page typed instead.

 

Thanks for helping anyway,

Hi Jelmer,

Based on my understanding, the PreviousPage is set only when the postback page is in the same web application. And please do check if the property is null before proceeding. Hope it helps.

  if (PreviousPage != null &&

      PreviousPage.IsCrossPagePostBack &&

      PreviousPage.IsValid)
