Maybe have a look here

If you evaluate the IsCrossPagePostback like so:

C#

if (this.Page.IsCrossPagePostback)

you will always get false, even if you are sure that it should be true. Instead, you should check the property like this:

C#

if (this.Page.PreviousPage != null &&
    this.Page.PreviousPage.IsCrossPagePostback)
