| A Grouping and Subtotaling Repeater for ASP.NET |
| DotNetJunkies |
| A recent project had a user interface requirement where data could be displayed two ways: either in chronological order or grouped by family member. I solved the "not so easy" grouping by family member requirement by modifying the Repeater control, as you'll see in this article. |

| An Interface-based Approach to .NET |

| In this article, Brian Boyce explains what interfaces are and how they're used, and provides some methods for working with them. He also demonstrates how interfaces differ from abstract classes. |

| Collection and Object Ordering |
| C# Corner |
| Net SDK provides a number of collection classes in the System.Collections namespace. We use these collection classes to store objects inside them and perform some operation on them later on as per application logic. Many times we need to re-order objects stored inside these collection. Most collection classes provide a method called Sort() to re-order their elements. The objective of this article is to use Sort() method to order elements stored in a collection class in a generic fashion. |

| Creating a Regular Expression Checker |
| devCity.NET |
| This article will attempt to explain the steps involved with creating a WinForm application that will validate regular expressions using the System.Text.RegularExpression namespace. The application will accept two inputs. The first input will be a string to search. The second input will be the regular expression that serves as our search criteria. |

| Creating Custom Collections |
| FLWS.com.au |
| Even though the FCL offers many different collection types such as the SortedList, ArrayList, Hashtable etc., sometimes it makes sense to create your own. Creating your own, custom collection can help to make your code more self describing. |

| Directory Picker Dialog |
| C# Corner |
| Although the open file dialog is a good tool for picking files, sometimes its the desire of the programmer to have a dialog that chooses a directory. This simple directory picker should get you started on this useful windows function. I wrote a previous article on this topic for Beta 1, but wanted to redo it for Beta 2. This Directory Picker in this article is also a bit different because it uses the "Large Icon" view of the ListView to traverse through directories. |

| Exposing Proprietary Data the .NET Way |
| MSDN |
| The .NET Framework comes with the OLE DB managed provider, which is meant to be a bridge that gives you immediate access to all the existing OLE DB providers. This component saves your current investments, as applications can continue successfully calling into existing OLE DB providers. The point, though, is another. In .NET, exposing proprietary data requires a more thoughtful choice, mostly because you have multiple and equally powerful options from which to choose.

| Longhorn Foghorn: Still Crazy After All These Bindings |

| Chris Sells explores how views maintain the current item and how they support filtering and sorting. He then looks at transforms for binding to data of one type and mapping to data of another type or in a different range of values. |

| Modularizing Object Collections With The Collections API |
| C#Today |
| The Collections API in the .NET Framework merits close attention by all .NET developers because of the flexibility it offers for writing applications in .NET. We can use it to manage groups or collections of similar objects, standardizing the way in which groups of objects are handled by our programs. In this article, Thiru Thangarathinam takes us through a tour of all the important collection classes by showing us examples, and then goes on to show us how these collection classes can be very useful in the day-to-day work of a developer. |

| Sorting a ListView with VB.NET |
| STANDARDIO.ORG |
| Every so often, while happily coding along in .NET, I’ll run into an object with a few methods that just don’t make sense. The .NET ListView object was just one of those. In VB6 it was a piece of cake to sort by columns in a ListView. All you did was pass it the index of the column you wanted to sort by. Now, in .NET, things have gotten a little bit more complicated. The gist of the new method is this: you must create your own custom class that implements the IComparable interface and overrides the Compare Function with your own code. Then take that class and set the ListViewItemSorter property of the ListView equal to it. Take a look at the custom class below and then see how it is used in the column click event of the ListView object. |

| Sorting MultiColumn ListView Windows Forms Control |
| C# Corner |
| If you want to sort on the first column of a ListView, simply click the Sorting in the properties Window and choose Ascending or Descending as a value. If you want to do sorting in all the columns of a ListView, you need to write custom sorting using the ListViewItemSorter property. This property allows you to assign the property to an instance of a custom class that implements the IComparer interface. |

| Sorting objects using IComparer and IComparable Interfaces |
| C# Corner |
| The System.Collections namespace contains interfaces and classes that define various collections of objects, such as lists, queues, bit arrays, hashtables and dictionaries. You can use a collection to store objects, some collection implementations would sort your objects by default when they are added to the collection and some would just add them in sequence. Once the objects are added to a collection if a custom ordered list (custom sorting) of stored objects is required IComparer interface form System.Collections namespace and IComparable interface from System namespace comes in handy. |

| Tips and Tricks |
| MSDN |
| During our last episode, we used unsafe code to do some image processing. In this column, we were supposed to spend some more time exploring unsafe code, but I've decided to change the program a bit. I have two motivations for this change. The first is that I haven't gotten around to writing the code yet. The second is that I'd like to answer a few common questions so that I don't spend so much time answering them elsewhere. Next month, we'll continue our exploration of unsafe code—probably. |

| Use Inheritance to Create a Custom TreeView |
| devCity.NET |
| This article demonstrates how to build a treeview where the nodes are based on different objects. A simple example is a folder and file hierarchy where each object needs different properties. A more complex example is an object model with a class at one level and with methods, properties, events, etc., at a level below that. In this example, Category is at the top level and AccountType and PartType are the second-tier nodes. Each class will contain a property that is not part of the other classes. In the real world each of these classes might be very different from each other. |
