When you work with a list of objects in Ajax, it is very important to add, delete, find objects in the list but JavaScript array does not contain any of them, We need to create an advanced list that works with all objects. In .NET platform, there is "Generic List" class that can do the same. My functions is like that one. We can say its name: an Array with dynamic size. (In JavaScript, it is impossible to remove items from an array or resize an array.)...

I recently needed a way to communicate with the users of a web page via a somewhat "interactive" manner, without using flash or java. Alert boxes were simply too obtrusive. I thought about MS Agent, but then it would only be compatible with IE. So I decided to build my own that would, in part, mimic the functionality of MS Agent, but be as cross-browser as possible....

Last month (September 2000) I gave you a quick tour of the script technologies you need to create a client-side environment that can execute ASP pages. I built a custom browser in Visual Basic® that is capable of processing ASP pages without Microsoft® Internet Information Services (IIS). This browser renders the HTML contained in an ASP page when you double-click on the ASP file. This information allows you to write ASP pages that are more versatile; they'll work both online and offline. When...

ASP is a Web technology that relies specifically on capabilities of Microsoft® Internet Information Services (IIS). For this reason, very few commercial products have attempted to provide an ASP-to-HTML converter. The problem with such converters is that you must work in conjunction with the Web server to trigger the ASP parser and find the intrinsic objects available. When you double-click on an HTML page from the Explorer shell, you simply ask the browser to retrieve and render the source cod...

Script callbacks in ASP.NET 2.0 is a feature whose time has come. Script callbacks can significantly speed up an application by limiting server postbacks. They also allow you to execute small portions of server-side code without having to manage the view state for reading or writing. In the August installment of Cutting Edge I began my discussion of ASP.NET 2.0 script callbacks, and this month I'll go into it further (see Cutting Edge: Script Callbacks in ASP.NET). I'll clarify some cross-platfo...

If you're a .NET developer, you must know how useful the StringBuilder class can be. I found this excellent article named JavaScript String Builderby K. Collins, and while the performance issues related to string concatenations were solved, I found myself missing a very neat feature of the .NET Framework: Composite Formatting. Composite formatting allows you to separate the "static" string elements from the "variable" ones, marking it much more readable, specifically when dealing with complex an...

Normally, HTML does not support nearest match. It always treats each key stroke as the starting of a new search. But, that is useless. If I type 'C', it will go to the first item that starts with C; if I type 'O' immediately, it will go to the first item that starts with 'O'. But in this implementation, it will go to 'CO'. If the user misspelled, the user can use the backspace key to delete the char 'O' and type another letter to select another item. The user can wait for 3 seconds to start a fr...

While most discussions of usability concern what sites are doing wrong and how to put it right, there are sites that are doing a good job, and you can adapt some of their ideas for your own projects. Finding ways to get more visitors to your site is an ongoing challenge. Sometimes the answer is to provide or promote a use that would not necessarily be associated with your kind of site—uses that go beyond click and buy. Why? Well, it's no mystery why department stores don't have clocks on their w...

ASP.NET client callbacks represent a neat and elegant way to execute server-side code without posting and refreshing the current page. I discussed ASP.NET callbacks in the August and December 2004 installments of Cutting Edge, considering them from the perspective of rendered pages making background callbacks to the server, sending input data to the relevant page, and receiving a response. The response string can then be processed by the client however it sees fit, often manipulating the rendere...

If you're involved in Web development you may have faced a problem that you couldn't find a good solution for—making client-to-server calls outside the current page. For example, you might want to validate the content of a textbox against data stored on the server asynchronously, without interrupting the continuity of the work or without forcing a full page refresh, which is particularly heavy for UI-rich pages. How would you code such an out-of-band call from the client to the server and back?...

Since its inception, ASP.NET has fundamentally been a server-side technology. There were certainly places where ASP.NET would generate client-side JavaScript, most notably in the validation controls and more recently with the Web Part infrastructure, but it was rarely more than a simple translation of server-side properties into client-side behavior-you as the developer didn't have to think about interacting with the client until you received the next POST request. Developers needing to build mo...
