.NET WinForm Controls (Windows Forms Controls)

What is a WinForms control? Windows Forms is part of the Microsoft .NET Framework and is a collection of technologies enabling you to create forms for Windows based desktop and client/server apps. Windows Forms developers can integrate and embed WinForms controls in their programs as reusable software components to provide specific visual functionality for their users. For example, a Windows Forms charting control can be placed on a Windows Form to visually display data as a chart or graph to the user.

In this .NET Win Forms controls gallery you will find a large selection of .NET WinForms custom controls and .NET WinForms components that a Windows Forms developer can use in their application. For example, there are WinForm controls that give you WinForm spreadsheet functionality, or that provide WinForms text editing capabilities. In general, these commercial grade, quality .NET WinForms controls are built by experts in the WinForm UI field - as such you can add their expertise and knowledge quickly to your Win Form application to give you greater functionality faster.

For example, there are many WinForms controls for charting and graphing included in this WinForm control gallery that you can download, compare, review, try and buy. These WinForm charting components will come with a wide variety of charts, graphs and styles that you can immediately make available to your users,without having to write the code, test it and then support it yourself. So you can quickly add functionality, save time, improve quality and save on maintenance costs by using third party Windows Forms controls that have been pre-built by experts.
