| Data Access with ADO.NET - Part 2 |
| ASP 101 |
| All right, so you're tired of hearing the theory and concepts behind ADO.NET. Me too. Let's look at and discuss some techniques and code that will allow us to read data into our ASP.NET web pages. I am going to be using the "pubs" database that ships with SQL Server to demonstrate the examples. I will also be introducing one ASP.NET control that we are going to use to display the data we retrieve: the ASP DataGrid. Although this control will not be covered at length, you will get a sense of its basic functionality and how ASP.NET strives to separate presentation and business logic. |

| Data Access with ADO.NET - Part 3 |
| ASP 101 |
| We now know how to access data and put it into a simple, readable form in our ASP .Net web pages, but there's so much more! In this article I am going to explain several more key objects that allow us to efficiently access our data in .Net. I will be using the OleDb flavor of ADO .Net classes for those of you who are not working with SQL Server, but just remember that if you are a SQL Server user, the difference is only in the naming of the classes you use and the connection string (refer to Part I of this series if you're not sure what I'm talking about). So let's get to work. |

| DataList vs. DataGrid in ASP.NET |
| MSDN |
| This month I want to look at two of the more specialized controls that come with the ASP.NET Framework: the DataList and the DataGrid. Both of these controls are full-featured data-managing tools. In addition to providing a simplified UI programming model for displaying data, ASP.NET includes facilities for binding data sources to these controls so you don't have to write all the code necessary to fish around a database and present your content. This month I'll compare and contrast the DataGrid and DataList controls, starting with DataGrid. |

| Developing A Vector Based C# Drawing Application - Part 3 |
| C#Today |
| In the first part of this series, Budi Kurniawan discussed the specification for a vector based C# drawing application. In Part 2, we looked at the Shape abstract class and the seven classes that inherit it. We also examined how an event handler works in a Windows application and we briefly discussed the System.Collections namespace. In this final part of the project, we will complete the development by discussing the DrawingArea custom control, the Color and Pen classes from the System.Drawing namespace, and object serialization - which is used to persist our drawing to a file, to be restored at a later stage. |

| Distributing Objects in Visual Basic .NET |
| MSDN |
| The challenge we have faced in the past is that it isn't always easy to give a developer an object, especially across the network. Objects in COM are always passed by reference, meaning that the COM object remains in the process and on the machine where it was created. The client code merely gets a reference to the object, so each method call is marshaled across the network, back to the original object to be serviced. With Microsoft .NET, we have the option of passing our objects either by reference like COM, or by value. When an object is passed by value, we not only get a copy of the data, but we get an actual instance of the object on our client workstation. The object itself physically moves from the server machine to our client machine, meaning that our client application not only has the data we need, but we have the business logic relating to that data as well. |

| Dynamically Changing the Color of Edited Items in a DataGrid |
| DotNetJunkies |
| In this article we will illustrate how to change the font color of all items that have been edited in a DataGrid. Essentially, it works like this: A user edits item one in a DataGrid. After the item has been successfully updated the next time the page is rendered (within the same session) the edited items text will be red and bold. The user can then edit an additional item (Item 23) and that also will be red and bold. So now, both item 1 and 23 will be red and bold
so the user can visually see what items h |

| Dynamically Create Bar and Pie Charts in ASP.NET (Step-by-Step) |
| http://aspalliance.com/ |
| Creating dynamically generated graphs and charts to graphically represent data from some data source in any application has often been a major requirement for developers. In most cases developers would have to resort to sometimes costly third-part component to accomplish these tasks. However, the new GDI+ classes and objects available in the Microsoft .NET Framework make it easy to create custom images and graphics on-the-fly, including leveraging information from any data source. In this article, I will walk through some simple steps of creating bar chart and pie chart images in ASP.NET based on information from a data source. |
