The ASP.NET company software improvement publication, that is a part of the Problem/Design/Solution sequence, is setup as a ebook that illustrates the matter first, then strikes to the layout (and seems to be at numerous layout possibilities), and winds up with the answer to enforce. The pattern venture for this e-book is a time-tracking chance, an program to log employee's time.

Each bankruptcy of the ebook seems to structure the basics of a enterprise program, beginning with the information entry, company, and presentation layers. the remainder of the booklet is spent a few of the positive factors that the applying wanted (exception dealing with, safety, workflow, etc.). lots of the eventualities within the chapters use a code-specific implementation to fixing the matter, instead of utilizing different instruments to be had to builders (for example, the workflow bankruptcy does not leverage home windows Workflow Foundation). notwithstanding there are a couple of instruments used, like Crystal studies and company Library.

The booklet has an enticing procedure in the way it implements the enterprise common sense; enterprise purposes are a lot diversified than own websites and different software forms simply because they rely on the luck in their company principles. that's one of many focuses of the ebook, developing the best way to constitution your code so you could deal with some of the enterprise wishes of the application.

The chapters that create particular positive aspects for the appliance (reporting, workflow, etc.) use a code-specific method of growing those positive factors. The e-book lays out the alterations to the database and information version, illustrates the saved tactics for the switch, after which strikes into the layout resolution. each one new function has a brand new ASP.NET web page that he demonstrates absolutely besides any adjustments to kinds, grasp pages, and so on. every one publication discusses the bankruptcy to the fullest aspect, from the proc to the completed solution.

The sort of the publication regularly follows the reason of the company challenge firstly. whilst the booklet illustrates code, the writer indicates the code first, and follows up with a proof of the answer. within the layout part, the booklet does speak about a few of the parts that it does use to accomplish the answer (such as Crystal experiences for reporting and company Library for exception handling).

I hoped the e-book used to be going to seem extra into utilizing quite a few layout styles inside of ASP.NET. even supposing there are a few, the structure is pretty well a similar during the program. also, the UI later does not use a lot ASP.NET AJAX JavaScript implementations or a script library like JQuery, yet leverages many of the good judgment at the server-side and, while important, leverages the replace panel control.

While i do not be aware of that i might use an identical structure, I do like a number of the positive factors he carried out within the app and glance to determine how i'll make the most of this for my very own improvement.

Let’s keep exploring. aspx page and specify btnDelete for the ID, and Delete for the text. In the btnDelete_Click procedure, enter the following code:. SubmitChanges(); } Only two properties need to be set for the data context in order to determine which record to delete: ENTUserAccountId and Version. If you don’t set the ENTUserAccountId, then the system will not throw an error or delete the record.

Indd 21 12/18/08 9:05:35 AM Chapter 2: The Data Access Layer As with the DataReader, a disadvantage of the DataSet is that it is not strongly typed, so you have to cast each field to its correct type when using a DataSet. Maintenance can then become an issue. DataSets are also more expensive than DataReaders because they return more information about the underlying DataTables. This can be an issue if you are marshaling objects across tiers. The third option is the typed DataSet. NET Framework was first released.

This line tells the data context to add the record to the table. SubmitChanges() line saves the changes to the database. aspx page the start page. aspx page. If you step through the code, you will see all the property set methods get called when the userAccount object is initialized.

All that without writing a single SQL statement! Pretty cool stuff, isn’t it?
