Allows you to hide all elements on an HTML page by their tag name. Extremely handy in getting around the "Windowless Elements" problem in IE, which is a bug that puts certain elements, most commonly select boxes, on top of any other element, no matter what. As you can imagine, this causes real problems with DHTML drop-down menus and such like. This is the simplest and quickest fix I've come up with, I simply set this function to run alongside the drop-down and all of the select tags vanish before a menu drops, then I run the show function when the menu retracts.

Highlight table row on rollover.

so you executed a query that took .5 second to execute and you want to bind that to a windows control. next you decide that you will need to have two controls bound to the same datasource. not a problem, except when you do this:
control1.datasource = datatable
control2.datasource = datatable

you notice that each control mirrors the other and you cannot pick two seperate and distinct values.

one way to solve this is to create two datatables and execute the query twice. unfortunately this now doubles your query time. bad idea.

here is the elegant solution...
