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.

Ceiling 58526 31 0.5331
Cos 65627 31 0.4754
Cosh 49281 31 0.6331
