ASP.NET Substitution Control
October 22nd, 2009 | 
Author: 
Tucked away on the toolbar is a little-used and often overlooked control. Not using this control could be costing you in performance.
The control I’m referring to is the Substitution control. The only time you’d use it would be if you had implemented page caching. You are using page caching, right?

HttpContext.Items[] vs Session[]
Since .NET first became available, passing data around during a request has become a lot easier. The ability to set a property has made that so. Still, there are times when setting a property just won’t do the trick.
One such time is getting data from the middle tier back up to the view separate from a DataBinding operation. That is, you databind a control to the middle tier and that method needs to set a value that will be used elsewhere in the view, not in the item that is being bound.
The natural, obvious tendency is to set a session variable. But there is a better way.

ASP.NET Three Tiered w/ Client Side Data
Last week, I created a tool that would allow the user to upload an XML file and have the web site process the file and return a report. All pretty standard stuff until you realize that if you want to use a three-tiered model you have to get the data that the client uploaded into a place that the Business Logic Layer (ObjectDataSource in this case) can see EACH time the object is instantiated.

Tracking Down Performance Issues in ASP.NET
Last night, one of my clients assigned me a problem that I thought was going to require one solution, and in the end it was just poor programming. But the process reminded me of the need for good debugging skills. Just how do you know where the performance problem is?
