This is a grid like Facebook Inbox style. This grid gives us the possibility of binding data and adding Facebook style events like removing the current row, expanding a row, and linking to another page.
The control uses the following methods:
* Send a jQuery AJAX request to a web server to get news in JSON format * Create rows and columns and bind data to table rows * Set the control style after data binding * Interact with user * Change and set styl...
I was given a task to add a captcha validation on a registration page. I found an article in CodeProject that is right on the target. The article solved that task, but I wasn't very happy about having to have an ASPX page reference, a need for a session variable, not easily customizable, distorting the whole image instead of letter. I'm in my vacation and spending a night creating a control to share and for future references....
Previously I came across a requirement to provide a functionality of something similar to a traditional combo box (found in Windows Forms) and a sort of multicolumn combo box in ASP.NET. I searched a lot on the net but found nothing suitable for my requirements. So, I decided to write my own control from scratch and here is what I call a multicolumn combo box. It is a combo box but with multiple columns and a textbox. You can search a particular row by typing the key column value in the textbox....
Well i have been wandering around here and ther for quite a few days in understanding how to dynamically create the controls during the runtime in VS 2008. All it ended out to be a very simple one. This is achieved through the methods Controls.add that is available with the panel or with each page. Well this works fine with panels and few other Containers but special care has to be taken when adding to the page.Controls.I l update regarding the same in some time....
The RadioButtonListcontrol in ASP.NET is used to display a collection of radio buttons that provide the user a multiple set of choices to choose from. You can select any one of the radio buttons from this list of radio buttons. You can bind data statically or programmatically to this control. The SelectedItemproperty of this control can be used to retrieve the radio button that has been selected....
ELMAH is an open source project whose purpose is to log and report unhandled exceptions in ASP.NET web applications. Since its first public release back in 2004 as a sample to the MSDN article Using HTTP Modules and Handlers to Create Pluggable ASP.NET Components, it has gained many new features and extended its support for newer ASP.NET releases - yet without dropping compatibility with older ones.
This article provides a comprehensive overview of the project as well as a detailed guide ...

This article shows how to build a custom validator and customize the error messages based on different conditions, as well as add a validation summary control and display error messages. This is very helpful if you have a lengthy form and you need to scroll down to hit a Submit button to validate the entire form. If the validation summary doesn't show the error message, the user could be confused. By default, the custom validator control doesn't render the error message to the validation summary...
It seems like everyone wants a blog these days—I know I did. But I couldn't find any pre-built ASP.NET blog code with the features I wanted, so I built my own. The great thing about building your own blogging application is that you get lots of practice with ASP.NET server controls, such as the Repeater, DataList, and Calendar. A blog application may seem like a simple exercise at first, but in fact it requires you to implement many features you'd need in a typical reporting application, such as...
This Tab Control is designed for ASP.NET applications. Although you can find many tab controls for ASP.NET from different 3rd parties but the beauty of this control is that its source code reveals internal working of ASP.NET server controls. Once you understand these deep internals, you can write your own professional controls just like 3rd party controls....
The simplest way to create a custom control in ASP.NET is to derive a new class from an existing control. Creating custom controls through inheritance this way is not really very different from creating any other derived class. Creating new ASP.NET controls from scratch, on the other hand, just may prove to be a more challenging undertaking. When you need a Web server control and none of the existing ones meet your requirements, you can derive a new control from one of the base control classes—C...
One of the most powerful features of ASP.NET is its support for custom server controls and components. ASP.NET ships with dozens of built-in controls, and developers can easily extend these controls or write their own controls from scratch. Server controls can be used to encapsulate complex user interface logic or business rules, and can benefit from design-time support like drag-and-drop and toolbox support and property builders. Custom controls pick up where User Controls leave off, providing ...
Most Internet applications now use Google Maps. Google has provide very rich API to use in our own applications. For the Google Maps, the latest feature is the "Panoroma view". Using it, I have created this Google Maps example. In this example, when the Google StreetView Man google Sreetview is dragged, the streets are highlighted wherever street view is enabled by Google. When it is dropped, the normal map is displayed. This way, the maps will be more little user friendly. This example uses Jav...
This post will show you how to use ASP.NET 3.5 Ajax COntrolToolKit History control with ASP.NET 2.0, As you might be aware of that microsoft has included AJAX with Framework 3.0, and from version 3.5 microsoft has also included History control in his AJAX Control toolkit, Using history control we can use browser back button to navigate backwards in the pages containing AJAX Controls, which was normally not possible till Framework 2.0. But if you are still using ASP.NET 2.0, then don't get disapp...
Tackles the problem of adding paging capabilities to any ASP.NET control. Also gives a number of tips and tricks useful when developing composite ASP.NET controls.From the programmer's perspective, one of the worst drawbacks of Microsoft® SQL Server™ queries is that they often return much more rows than actually fit in the application's user interface. This unfortunate circumstance puts developers in a dilemma. Should they create a very long page that takes users a while to scroll through, or is...
In January I looked at how to compose ASP.NET server-side controls from other standard controls. The example I offered was a Fahrenheit-to-Centigrade converter composed of two textboxes and two edit controls. However, rather than composing the server-side control from several standard controls as I did in the January issue, this month I'll render one on the fly. In this column I'll take a closer look at server-side controls, especially with respect to round-trips between the browser and the serv...
Microsoft Live Labs Volta is Microsoft's emerging toolset that enables developers to build multi-tier web applications by applying familiar .NET techniques and patterns. The intended use of this toolset is for Developers to build web application as .NET client application, and then specify the portions of the codes that will run on the client and server side. The compiler then creates cross browser JavaScript, Web Services, communication, serialization, security etc. to tie the tiers together. T...
