You often need to update some portion of the code based on a user-triggered event or after a period of time. Usually, this isn't possible unless the whole page is posted back which, however, is not the goal. We'll take a look at a couple of solutions ASP .NET offers for such cases: UpdatePanel with
Well designed websites do not consist of completely independent pages. They give the feeling of a continuously running application. Good design practice is to offer the site visitors similar interface and user experience no matter where they are on the website. The most common shared interface between different pages of the same website is about
A good practice in ASP .NET and in programming in general is to divide the code into reusable blocks. This is applicable to HTML code too. In ASP .NET it is achieved by creating User Controls.User controls look similar to web forms. They contain HTML and control tags, they are saved in .ascx files and
Cookies are small files that are stored either on the user's hard drive or in the browser's memory. Their main purpose is to keep information for later so it can be used for more personalised browsing experience for example.Their simplicity makes them useful long time storage on a variety of applications. However, being simple text
There is no strict definition of ASP .NET rich control but generaly these are controls whose object model is largely separate from the HTML they generate. Rich controls are still handled as single objects, they only differ from normal controls in terms of more complex HTML and user interface being generated. Let's take a look
Quite often there is a difference in how a developer tests a web form and how a user uses it. Users may: leave random characters in a field that requires a telephone number to be the input. For example, if there is a code that tracks phone calls and compares them to the phone data
Web applications cause a problem that is not present on traditional applications stored on the user's PC (tablet/phone). The problem is the following: the user connects to the server and requests a page, the page is delivered, the connection is stopped and then all the page objects are deleted from the server memory. This stateless
ASP .NET provides a new way to handle dynamic web forms. Unlike the conventional style where the developers had to adapt and improvise with HTML tags and attributes, ASP. NET server controls automatically provide their HTML structure. This allows the developers to focus just on the desired behavior. These server controls behave like objects and
