The latest Microsoft patch for Internet Explorer included a change to ActiveX requiring all interactive controls to activate before they can be used. This change has impacted web applications all over the world including Dundas products.
While the Chart can still be viewed fine after this patch as an image or an ActiveX object, the interactivity included in ActiveX objects, such as Flash, require a preliminary click by the user. This is not attractive functionality and fortunately Microsoft h...

One of my most used ASP.NET control is DataGrid. Presenting data from tables is very easy and nice with only one exception - the page navigator. Showing only page numbers or only two links (to previous and next page) is insufficient for me, and completely inexplicable for my clients. So I decided to create DataGrid Server Control, the main task of which is to providing paging alphabetically....

Recently, Microsoft released the source code for the built-in Providers that ship with the .NET 2.0 framework. While I never downloaded them, this release caught my attention, so I started to study this new feature of ASP.NET. I was really impressed by the power of the build providers (I don't know why they didn't get my attention until now), so I decided to share my weekend experience with you....

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...

The Microsoft ASP.NET Ajax Toolkit offers excellent tab control that organizes several views within a single page when each view is presented one at a time. It is more difficult to use this control to manage tasks that are split between different pages. The TabStrip control presented in this article could be used for navigation between multiple pages....

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....

Let's say your boss just gave you an assignment to create a "Trading Post" type of module for the company intranet that is running on DotNetNuke. In the past, you would have spent nearly half an hour just setting up the development environment, and hours creating the Data Access Layer (DAL) and the code. All that has changed with the recent enhancements to DotNetNuke and the DAL, in the creation of the DAL+. This tutorial will show you how to create a DotNetNuke module using the new DAL+, an ext...

We often get forum posts here asking "How can I tell if a user's Session is timed out, and perform some action in response?" Often this involves the incorrect assumption that the Session_End event can be used for this. ASP.NET implements a rolling timeout mechanism that extinguishes the session information for a user if no request is received within the timeout period. Session_End happens on the server automatically regardless of whether a user has requested a page, so the idea of using it to do...

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...

I've had some success embedding a resource in the assembly of my web custom control, but I'm having problems thinking of how to do it with images. Every article I've read seems to be geared towards Win Forms and Bitmaps. Can I embed, and then retrieve and display a jpeg or gif from the assembly for a web custom control? Basically I want to render an image as part of the control. Not designer, but actually for the real displaying HTML too....

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...

The compiler then creates cross browser JavaScript, Web Services, communication, serialization, security etc. to tie the tiers together. T...
