Differences between RegisterClientScriptBlock & RegisterStartupScript and how they work with AJAX Update Panel  Version: 0.00     Price: $0.00

We usually write the javascript functions on aspx page.

If we want dynamic script then we can not write on aspx page because in many cases like script may require some data from database or any operation that can only be done from code behind.

In this case we can use RegisterStartupScript & RegisterClientScriptBlock functions to include Javascript on page from code behind....

ASP.NET AJAX provides many ways to improve user experience and performance. One of the most common way is undoubtedly the UpdatePanel control. The UpdatePanel control provides partial page rendering capabilities to your web forms. Commonly developers place data bound controls such as GridView and DataList inside an UpdatePanel so that only that area of the web form is refreshed after a post back from within the UpdatePanel. However, there is still better way to use UpdatePanel with grids and lis...

When using Microsoft's ASP.NET AJAX framework and an UpdatePanel whose ChildrenAsTriggers is set to True (the default), anytime a user interface element within the UpdatePanel would normally cause a full page postback, a partial page postback is performed instead. For example, clicking a Button Web control or selecting a different item from a DropDownList control whose AutoPostBack property is set to True normally causes a full page postback, but if these controls are within an UpdatePanel, a pa...

jQuery being common and mostly used these days, usually we come across scenario in which we have to use jQuery for those HTML elements that are placed under the ASP.NET AJAX UpdatePanel. This works fine unless partial postback is done, but in case of postback, we loose the style or behavior of these html elements. This article describes different ways of solving this problem....

Nikhil recently posted a nice blog post that includes a new ASP.NET AJAX-enabled control called "HistoryControl". When added to a page it allows developers to programmatically add logical views into a browser's history list. This enables you to make AJAX enabled sites much more useful, and to follow the standard back/forward navigation paradigm that traditional web apps follow....

Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Refreshing An UpdatePanel With JavaScript  Version: 0.00     Price: $0.00

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...

Like most people, I use more than a few of Google's web applications on a day to day basis. I think what I like best about their applications is the elegance of the user interface. Just recently I started using their analytics web application to learn more about what drives visitors to my site. One of the pages within the tool is a dashboard screen that displays a handful of different panels, each containing summary information pertaining to the web traffic for my site. Some of the panels di...

I recently was working on an Asp.Net project that contained quite a few search pages. These pages all followed a similar structured pattern where the user had a set of fields they could filter on by typing in values and pressing the search button. The results were displayed in a GridView where the user could sort by clicking on column headers, export the results to excel, etc... To help improve user experience, we placed each of the GridViews in an asp UpdatePanel so while the user refined th...

I hadn't tried this before, but I can see how it would be useful. In the web application I am currently working on, we have a number of pages with GridViews that are contained within UpdatePanels and searching, sorting or paging can take up to five seconds depending on the current load. During that time we display a progress indicator, but we typically do not disable the GridView. As a result, all of the controls within the GridView also remain enabled and mousing over them gives the indicati...

Windows applications are more stable than web application. Even if the web is not that stable like a windows application, there are lot advantages of building Web Applications and one thing that we remember as ex-Windows programmers is that the Forms did not Flicker in front of the eyes of the user. This irritates a lot of users. Microsoft came back with a good solution for this problem and they introduced Ajax. In this Article am going to show you how you can create Flicker Free pages....

Using Ajax, Beyond UpdatePanel

I have always been wondering about the UpdatePanel in Ajax, at times it just looks like a Magic Wand to me. If you already have an aspx and want to incorporate Ajax, just touch this Magic Wand and your page is Ajax ready! However, one more such Magic Wand provided in Microsoft Ajax is ScriptServices and PageMethods. These two are equally (if not more) handy when we want to Ajaxify our page, compared to UpdatePanel. In this article, I would take a look at these two as an alternative to UpdatePane...

As an example; imagine we have a database with all the zip codes from the USA that allows us to lookup the city for a particular zip code. When the user types in the zip code, the code looks up the city name. When the user clicks on save, the complete address is updated on the server side. The server can only save an address if it has a zip code with the corresponding city name (business rule)....

When consuming things like long web services or RSS feeds from external web sources, it might be nice to load all of the important parts on the page first and then load the slower loading part(s) later. This example will demonstrate how to load multiple blocks of RSS headlines after the main body of the page has had a chance to load. While the page is loading, placeholders are displayed to indicate that additional content is coming. After the page loads, the content for the placeholders is retri...

Last week, I was developing a credit card payment module for a software platform of one of my clients. As most fellow developers may know, authorizing a credit card payment may take some time, say up to 10 or 15 seconds. Since I did not want to keep customers waiting for a page which seemingly was not loading at all, I decided I wanted some method to clearly indicate to the customer his or her request is being processed, while at the same time keeping him or her from button bashing because they ...

Atlas: ModalUpdateProgress - An UpdateProgress Control in Modal Popup Style

ASP.NET AJAX has a cool UpdateProgress control that provides a visual indicator while one or more of the UpdatePanel controls are being updated. However, it will be much more useful if all other elements on the page could be disabled when the UpdateProgress is shown. This led me to build the ModalUpdateProgress control in which the UpdateProgress will act as a modal popup....

UpdatePanel is a great way to add Ajax features to an ASP.NET application at a minimal cost. Because it's based on regular postbacks, it also degrades gracefully when JavaScript is not present. But one thing it doesn't do well out of the box - and this is actually the case for any asynchronous update to the DOM - is informing screen readers that new content is present. This article and the accompanying code show how to work around that problem and give assistive technology users access to the be...

This is one of those problems that isn't technically difficult, like writing a word processing program, but rather is just a matter of finding the right code sequence to make it work. Much of the AJAX documentation shows how to use the controls placed in HTML markup. However, there are some situations where the programmer would prefer to add controls to a page dynamically from the code-behind (see my article Building ASP.NET Web Pages Dynamically in the Code-Behind). Using AJAX controls in this ...
