TITLE tags for hyperlinks - little datagrid usability thing
[updated based on feedback from Rick and Fabrice]
Master / Detail pages are a snap to create with ASP.NET, but they can be frustrating on the end user. If the information you're looking for isn't on the master page, you end up clicking back and forth to find the record you want. From a selfish point of view, those unneeded round trips to the server are also a waste of server CPU and bandwidth.
So here's a simple little feature that can save some clicks - a "title" attribute for the edit links. Mouse over them to see what I'm talking about:
| Edit * | Requestor | Phone Extension | Department |
| 200454378 | Nathaniel Pemberton | 7012 | Marketing |
| 200454379 | Bart McKinley | 2000 | CEO |
| 200454380 | Nathaniel Pemberton | 7012 | Marketing |
| 200454383 | Walter Jennings | 4302 | HR |
*mouse over Order ID for details
The idea is the same as an alt tag for images.
<a href=http://images.google.com/images?q=monkey title="Monkey pictures!">Click Here</a> = Click Here
Works in IE and Firebird. Haven't tested in Lynx.

<script runat="server">

//Nothing exciting here - just creating a dummy datatable to bind to.
DataTable dt = new DataTable("Orders");

dt.Columns.Add(col);
