| Adding a Default ListItem in a Databound Listbox in ASP.NET |
| 4Guys from Rolla |
| In a previous article I showed how to use databinding to automagically populate an ASP.NET's listbox Web control with just a few lines of code. (If you've not already read the past article, be sure to do so now.) I've received a couple of feedback emails from folks since publishing the article asking how to add a default option to the listbox. That is, they want to add a listitem to the listbox, like: -- Please Choose an Option Below--. In this brief article we'll tackle this topic and more!

| ASP.NET Control Validation in Groups |
| The Code Project |
| The validation controls of ASP.NET offer a great deal of flexibility and comfort when you need to write data entry pages in your web application. They provide the ability to ensure valid data in the input fields in a rather declarative than procedural way. So far so good. Imagine a form that handles different payment methods. Depending on the selected method different fields should be mandatory while others remain empty. |

| ASP.NET Validation Controls |
| DotNetJunkies |
| Input validation can be a tricky thing. Ideally we should validate the data on the client side to prevent unnecessary round trips to the server. That requires JavaScript. But not every browser out there processes JavaScript (hard to believe, isn't it). And even still, changing the display characteristics to show errors in the input is not always supported. Not to mention, a slightly unethical person could recreate your page, and bypass the validation all together. Ugh! This leaves us with server-side valida |

| ASP.NET Validation Controls Samples For Beginners |
| .netBips |
| Most of the times while submitting forms we need to validate the user input for certain criteria. In ASP there was no other way but to write our own server or client side validation routines. ASP.NET frees the programmer from performing common validation tasks through the use of special web controls called validation controls. These 10 code samples will show you how to use all of the available validation controls. |

| Building a CheckBoxList Validator Control - Part 2 |

| As promised, this week we will be going over how to add client-side JavaScript to a custom validator control. <b>But</b> last week I was asked a very interesting question. What validator control should I use to validate that a CheckBox was checked within a CheckBoxList? The anwser was simple, NONE. None of the validator controls in the .NET valiator control suite does this type of validation.

| Building a Custom Validator Control - Part 1 |
| DotNetJunkies |
| Well, the DotNetJunkies are at it again. We are starting our next book on building custom .NET server controls. So to follow with this category I'll be writing server control articles now and again. We'll be starting off slow with this article which illustrates how to derive your custom control from a base class and add your own features. In this article we'll demonstrate how to derive a class from the BaseValidtor class to create your own validator control. Why would you do this? Well, in short the validat |

| Building a custom web control: a textbox and validator in one! |
| Wimdows.net |
| In this article we will have a look at implementing a custom web control. This web control will inherit from the TextBox web control, and will automatically add a required field validator at run-time. This way, when we need a required field text box, we don't need to mess about with the required field validator, but instead we just define an instance of our custom web control. |

| Building a DataGrid with Add and Edit Features |
| DotNetJunkies |
| The DataGrid server control is one of the most widely used controls in ASP.NET-based projects to display data in a table form. When using a mixture of database- and manually-driven DropDownLists, placing them in a DataGrid can be confusing. In this tutorial, I'll focus on resolving this issue using an example of an expense entry and reporting system. |

| Creating a Weblog using JScript .NET and ASP.NET |
| http://webdeveloper.earthweb.com/ |
| A Web Log is a Web page that represents a personal journal - a web log is informally referred to as a "blog". Blogs have frequent updates and individual updates are usually short. Some web blogs, like Slashdot, have a number of people working on them and provide a degree of interactivity by allowing readers to post comments about blog entries. Blogs have become so popular that services, like Blogger.com, make it easy to create and update your own web log. Developers like to do things their own way and have the ability to create their own blog - this article discusses how to create your own blog using JScript .NET and using ASP.NET. |
