By default, the GridView displays data using the BoundField object which displays data from a given column in the data source with no real modification. By contrast, any content you desire can be placed inside a TemplateField element. This makes it ideal for setting up validation through the use of validation controls.

TemplateFields may contain static HTML/CSS, ASP.NET web server controls as well as databinding statements. They also offer great flexibility by allowing you to include a variety of templates to cater for the different states of the conditions arising within the GridView. There are several types of template which may be added inside a TemplateField object; the main ones are described below.

The HeaderTemplate offers a way of customizing the information which will be displayed in the header of the column in which the TemplateField is located.

The ItemTemplate is used to display the information which you want displayed for each row of data when the GridView object is not selected for editing.

The EditItemTemplate is used to hold the information which you want displayed for each row of data when the GridView object is in edit mode. It is here that you would place the controls necessary for validation.

Most of the time, information currently held in the database is displayed by adding a TextBox control inside the EditItemTemplate and databind it to the appropriate column from the data source using a statement like Bind(“FirstName”). Inside the same EditItemTemplate, you would then place the necessary validation control. For example, if you want to ensure that the field is not left blank when the form is submitted, you would insert a RequiredFieldValidator control.

Although it has a similar syntax to Perl, the text is embedded with special PHP tags, so the developer can actually go back and forth between using PHP and HTML. This is convenient because it can decrease the amount of HTML codes that need to be written. Another reason that people use PHP with regularity is the fact that it can communicate across a number of networks using different protocols such as IMAP, HTTP and even POP3.

The original developer of the language was Rasmus Lerdorf and he created it in the mid’90′s. However, it has undergone many different re-incarnations and version updates since’98. These upgrades have become a popular reason why the use of PHP web development has become one of the favorites used by web page designers.

PHP web development can be used in a number of applications because it can communicate across a vast number of networks. It is not as limited as other languages and development tools that are available for the same purpose. Some of the protocols that it uses include HTTP, POP3 and IMAP. It supports command line interface applications and can be used for standalone graphics.

The last version of PHP concentrates on the security of the web pages. They will address the issues of the last version. Version 6. 0 will also have the added convenience of supporting Unicode.

Although the current version can’t support Unicode, the forthcoming version 6. 0 will be able to. PHP web development is one of thousands of languages used by programmers and developers. The many improvements that the PHP web development software has made it increasing popular by those who create web pages.

A textbook can supply you with all of the HTML codes that you might need for web design. It can list every possible command that you could execute in a program like Adobe Dreamweaver. It can even help you to get an understanding of the different parts of the program by definition. However, it will never teach you to use the program properly. What you need is a training program that offers a hands-on solution, allowing you to learn by example and through experience, rather than by merely reading and memorizing information, commands, and codes. Books are only useful if they are combined with adequate training and actual hands-on experience. In and of themselves, they are practically useless for learning how to use computer programs.

Adobe Dreamweaver training can allow you to see things firsthand. This will let your brain make a much better connection between commands and what they do than a list of definitions ever will. Interactive training adds that aspect of seeing and doing at the same time, which can make you a better web designer. Dreamweaver training videos, for example, can show you a real person using the actual program you’re trying to learn, making the association between knowing and doing much easier than a textbook ever could. Also, you can find courses that offer tutorials and one-on-one interaction, which can give you another level of understanding and assistance in learning the product.

Whether you’re a professional designer or just learning Dreamweaver for fun, training software for Adobe Dreamweaver will prove to teach you much, much more than a book ever could. Even if you just need to know the basics, you can learn them quickly, and get on to designing your webpages, and spend less time trying to memorize facts and lists of commands that might not be very useful to you until you make the connection. Our brains tend to like pictures and examples better than useless, memorized information, so give it what it wants, and you’ll learn that much faster.

Computers now offer us a whole new world to work with. Using training software to learn the proper operation of programs is not a new concept. People have experienced hands-on learning with computer software for many years, and it makes the process much easier for everyone involved. If you want the best, fastest chance of learning and enjoying the web design process, you need to try the training software approach and forget about the books.
