When I implemented the up and down arrow images for the Data Grid control in Part 18 of the An Extensive Examination of the Data Grid Web Control article series, I put the code that added (or removed) the arrow images in the ASP. Specifically, the code enumerated the Data Grid's properties.
The built-in up and down arrow images are used here.
In this article we looked at building a custom Grid View server control (along with a custom Bound Field control) in order to automatically display up and down arrow images for the sorted column. This article's text has not been updated to reflect these changes.
I encourage you to still read this article to get an overview of the rationale behind the custom Grid View control and to understand the initial architecture. NET 2.0, the Grid View control serves as a much more functional and feature-rich choice.
