Cross-Page Navigation Techniques in ASP.NET
Ting (one of the key guys on the ASP.NET Team) has posted an awesome blog post detailing all of the different techniques for doing Cross-Page navigation in ASP.NET, including: client-side redirects, server-side redirects, the new ASP.NET 2.0 cross-page posting feature, the new ASP.NET 2.0 multi-view control, and the new ASP.NET 2.0 Wizard Control. In his post he includes a sample for each.
Definitely something I’d recommend to check out and review.
Hope this helps,
Scott
