In our AJAX QuickBuild event yesterday, Simon Allardice demonstrated for everyone how to access the value of a server control from client-side script. Let me share with you his tip/trick. It is quite simple. Here is the markup of a content page - notice the script tag: <% @ Page Language ="C#" MasterPageFile...

Although the ScriptManager has a property named IsInAsyncPostBack to determine an AJAX call, the control is scoped to the page it is contained in.

LINQ to SQL came out with 3.5 and I am still amazed that many people accomplished to stay away from that simple technology. When you ask them, they've heard about but they are not sure how everything works together. Instead of looking it up to learn to see if there is something that may improve their...
