There are several key aspects to multi-agent computing, distribution and independence are among them.

I really like the telerik radgrid. Their product ain't cheap, but you get a lot of controls and features. And the data binding support is pretty good, both in a simple asp.net data source binding way and in a more custom handle-your-own-databinding-events kind of way. |
To be honest, in Java there is not really an argument against overriding [equals()][1]. If you need to compare instances for equality, then that is what you do.

You can use mutliple classes in the HTML element's class attribute, each providing part of the styling. So you could define your CSS as:
.ourColor { color: blue; }
.ourBorder { border: 1px solid blue; }
.bigText { font-size: 1.5em; }
and then combine the classes as required:
<h1 class="ourCol... |
Use list comprehensions when the result needs to be iterated over multiple times, or where speed is paramount. Use generator expressions where the range is large or infinite. |
Iterating over the generator expression or the list comprehension will do the same thing. However, the list comp will create the entire list in memory first while the generator expression will create the items on the fly, so you are able to use it for very large (and also infinite!) sequences. |
It's best to use a combination, and you'll have to use your own judgement. Here's the guidelines I use:

When you `throw ex`, you're essentially throwing a new exception, and will miss out on the original stack trace information. `throw` is the preferred method. |

The rule of thumb is to avoid Catching and Throwing the basic `Exception` object. This forces you to be a little smarter about exceptions; in other words you should have an explicit catch for a `SqlException` so that your handling code doesn't do something wrong with a `NullReferenceException`.
