GridView Control Example

Example Summary and Logic

The goal of the adapter for the GridView control is to create a <table> that is slimmer and better organized than what is produced without the adapter. You could, of course, rewrite this adapter to completely eliminate the <table>, replacing it with a variety of <div> tags, etc. However, a grid, fundamentally, is a table so it seems logical to leave it as such.

The adapted GridView eliminates the use of inline styles. Rows within the <table> are organized into <thead>, <tfoot> and <tbody> sections. These make it easier to read and understand the markup. More importantly, these sections make it easy to create CSS rules that govern the appearance of particular rows within the <table>.


Working Example

What happens when we run the Math methods over and over again? Here are some raw timing statistics.
