One of the common requests in ASP.NET is to submit a form when visitor hit an Enter key. That could be a case if, for example you want to make Login Screen. It is expected that user just hit enter when he insert a password instead to of forcing him to use a mouse to click login button. If you want to make search function on your web site, it is frequently required to give a possiblity to hit enter after you insert a search terms instead of mouse click on a Search button
Microsoft surprised a lot of people with the release of their initial white paper on HailStorm. It contained the frank proposal that HailStorm services would be completely accessible from any platform, and not just Windows. As the white paper put it:
Apparently some developers worry about what their sites look like and as a result they actually work with a graphic designer or layout artist (I'm not up on the politically correct title) to get it looking spiffy... who knew! ;) This is where code-behind really is a godsend. You just send the graphics person the Web Form portion of your page and they work with that. They never get to see (or mess with and break) the code that you've spent days working to get just right
In the previous tutorial (Accessing MySQL Database with ASP.NET), we learned how to obtain, install, configure and run MySQL on Windows. Later we learned how to create new tables and display records using ASP.NET DataGrid control.
I initially turned to ADO.NET's DataRelation and DataSet objects so that they could handle the relationship management for me. The DataRelation object's capabilities are dead on for single tables with self-referencing keys or multi-table relationships without self-referencing keys. If your current situation falls into either of these categories, you'll want to use the DataRelation object scenario to recursively build your hierarchical structure rather than the solution described in this article. In fact, most tutorials you'll find in books or on the web deal with either of these two situations. However, I have found that the DataRelation object is a little flaky when it comes to combinations of self-referencing tables and multi-table nested relationships, particularly with those that run more than 2 levels deep or have their root level row with the same PrimaryKey as its ForeignKey ParentID. Of course, if you are using foreign key constraints, you can't just set the ParentID to 0.
