In Part 2, we will understand how the same tasks can be done without Linq Data Source control.We will use the same Employee table to understand the custom databinding using LINQ. I've just returned to 3.5 after a year or so, previously only dabbling with 2.0.If you are learning asp: List View control while reading this article, you may copy-paste code described here.
