In order to refresh an UpdatePanel control via script we need to trigger a partial page postback for that UpdatePanel. As discussed in previous articles, any control within an UpdatePanel that would normally trigger a postback when clicked will trigger a partial page postback. For example, a Button Web control placed within an UpdatePanel will cause a partial page postback when clicked. It's also possible to have Web controls outside of the UpdatePanel trigger a partial page postback. This is ac... |

JavaScript is an amazing language which can be executed in two very different environments; it can run within a browser (client-side) as well as within a Microsoft IIS web server (server-side). Running on client-side, JavaScript is a good workaround for HTML limitations and helps building user-friendly web applications (it's also called Dynamic HTML). Running on server-side, JavaScript enables building dynamic Web pages (for example reading data from a database and presenting it in a Web browser... |

Let me also guess that you've heard about DHTMLX, an Ajax components library for building rich web UI. My goal is not to teach you how to use dhtmlx components, ... |

In this article, we will discuss about error handling in javascript. Most of the modern languages like c++, c# supports error handling. In the same line, javascript also supports error handling constructs. These constructs will help the developer to handle errors within the code. JavaScript provides two constructs to handle the errors:
1. try/catch block
2. onError event... |

I have a series of pages on my Web site, with different want ads on each page. Users click on the ads they want to see. In order for me to identify users and put them in touch with the person who placed the ad, I request that users register with a user ID, password, and e-mail address, which they keep for future visits. Before registered users look at the ads, I would like them to enter their user ID and password. Then, when they click on an ad, a form is sent to me with the user ID, password, a... |

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... |

To the majority of ASP.NET developers, the DataGrid control is a basic and essential tool, much like the rolling pin for serious pizza makers. The DataGrid control in ASP.NET 1.x is an extremely powerful and versatile control and a great server tool. But you can make it even more powerful with the addition of just a little bit of client-side script. Until now, I hadn't played with JavaScript and DataGrid controls together. Recently I ran into a wonderful piece that Dave Massy wrote a couple of y... |

There's a trend in the software industry towards moving much of the burden of code writing to the infrastructure of the underlying platform. A variety of development platforms ask developers to provide a high-level description of the information they need in a relatively loose syntax, instead of hard-coding every single byte of it according to a strict set of syntax rules. It is now common for developers to use an XML dialect to describe the desired result and have a compiler or runtime engine p... |

Staying on that bleeding edge can be a great kick, but it can also leave you scratching your head. You may have come up with something totally cool for your Web site -- but since no other Web site has the feature, you end up wondering where to get help. I am always looking for ways to improve the performance of Web pages and to improve on coding styles. I have been able to compile from different sources some great suggestions (some my own) from people on the Internet, including ways to improve A... |

As a child , I was fascinated with the StarTrek scenes where captain spock would talk to the computer and it seemed that the computer would have intelligence from the responses. While we are all waiting to see the day when mankind will be able to embed intelligence in machines, as of this day that thing has not happened. What is really possible is to have a fact based rules evaluation system, to which you provide facts and ask it to evaluate the rules against this facts. The answer is a logical... |

Override the default implementention of client side validation of ASP.NET and modify the default functionality by adding focus to error fields and individual alerts for each invalid field.Since I started working with ASP.NET Validation controls, I thought that they were good stuff, but lacked functionality in the client validation functions. Diving into the internal code of the ASP.NET web control's validation infrastructure, I found out that the functions can be overridden. In this article, I'l... |

On the forums that I participate in (and at work) I often see ASP code making extensive use of string concatenation, and although I want to point out why it's bad and how to improve it, I usually bite my tongue and say nothing because to cover the topic in sufficient depth would take more time than I want to spend! It is disappointing to see that so many developers are unaware of the performance implications of doing so, and in other cases where inefficient techniques are used I would normally p... |

As a Web developer you sometimes need a dab of JavaScript; maybe to pop up a message box or a new window. They seem like such simple chores, yet it can take a considerable amount of coding and debugging to create a flexible solution. Writing server code is fairly straightforward for someone with a programming background. Writing client-side code isn’t a foreboding task either — for the adventurous type. However, mixing server code with client-side code can get rather tricky. The many ways to go ... |
