I am currently working with conversion of ASP Classic web application to ASP.Net 2.0 and I have to deal with a lot of client-side script. Before, I used to insert an alert( sampleValue ) to be able to view the current value of a variable until I found out that about “debugger” keyword in JavaScript....

I have been using log4net for a year and a half now and there are scenarios where I'm expecting it to log some data only to find out that it's not logging. I know two possible reasons of log4net not logging: 1. It is not yet configured to log. I am configuring log4net through the XML configuration...

I'm working on a GridView and I'm databinding a List<BusinessObject> to it. All is well until I tweaked some code and suddenly, I got this System.Web.HttpException with message A data item was not found in the container. The container must either implement IDataItemContainer, or have a...

I hope that one day I will wake up that all web-shoppers are using IE7, firefox and opera... and IE6 will be burned into forgetten in the e-commerce arena.
