Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET.

These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!
