| A Small Data Class |
| FLWS.com.au |
| This is a small code sample to demonstrate how simply you can create an array and use it as the DataSource for a ListBox control. More than that though, I'd like you to pay close attention to the small Class called ListData that serves as a Data Class. I saw a Class similar to this one used in an example on MSDN, and, because I can never find anything twice on MSDN, thought that I'd better document it here on ShowUsYourCode. |

| 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!

| Adding Blank Rows to a DataGrid |
| DotNetJunkies |
| In one application I had the requirement to add a blank row after every 10 rows in a DataGrid rather than use paging. There is no in-built way to do this with the DataGrid, but it can be easily done by modifying the DataTable that the DataGrid is bound to and by writing some code in the DataGrids ItemDataBound event. This how-to article will describe how it is done. |

| An Introduction to Mobile Programming in C# |
| C#Today |
| With the expansion of the web away from traditional browsers, current technology has brought the internet into mobile devices. Microsoft has constantly improved its support to such devices, and the introduction of the .NET framework has taken this support a step further. With .NET we can program for a mobile device as a normal web page and the Common Language Runtime and .NET framework will take care of rendering the data in the appropriate format, i.e. as HTML for browsers, as WML for mobile phones, etc. In this article Niranjan Kumar introduces us to programming for Mobile devices using C# and ASP.NET pages. This is illustrated with a Stock List application that accesses a SQL Server database and lists available stocks on either a Mobile device or HTML browser. |

| Application of the Cache Subsystem for Web Applications |
| C#Today |
| In this article, Eric Rhea explores two approaches to utilizing the caching system. First, he talks about how to make use of the cache subsystem from the web-form code. Then, he takes a look at exploring how to make use of the cache subsystem in the code behind. While doing this, he seeks three answers: (1) how to improve performance, (2) how to make use of similar techniques in both code areas, and (3) how to cache an object which is indeterminate in length and whose values you do not know in advance, and one which you cannot cache using the web-form directive. |

| Ask the DotNetJunkies: Dynamically Populating An ASP.NET ListBox |
| DotNetJunkies |
| When dynamically populating a list box using listbox.items.add, asp.net generates the same string for the HTML tag OPTION's value and text. In the past, I would put a table key in the value while filling the HTML text with various information. What are methods for splitting the listbox attributes? The .net framework examples do not address this type of dynamic filling of the listbox. Thanks, Ken (your interview on MSDN was great) |

| Ask the DotNetJunkies: Working with Properties and Data Types |
| DotNetJunkies |
| How do I change forecolor of Label programmatically? I have tried... lblTest.forecolor="green" but keeping getting "System.String cannot be converted to System.Drawing.Color" error. Any help would be appreciated. This is a good question because it gives me the opportunity to address some of the fundamentals of how the .NET Framework handles data types. In classic ASP a color name and a string didn't seem any different in that they were both string values. In .NET data types are much more important and much |

| ASP.NET Localization Part 1: CultureInfo |
| DotNetJunkies |
| The .NET Framework provides built-in mechanisms for localizing applications. ASP.NET internally uses Unicode and the String class of the .NET Framework also uses Unicode. The use of Unicode enables you to easily specify different encoding types for the response data sent to the client. While the .NET Framework will not translate your documents from the language they are written in to a different language, the built-in mechanisms will reconfigure output such as DateTime objects to their appropriate format. |

| 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. |
