What is a .NET component? .NET components are pre-built pieces of software that you can re-use within the Microsoft .NET Framework (pronounced dot net framework) to help you create your application faster and hopefully with fewer bugs. By re-using .NET software components you not only save time and money, but you also get the opportunity to use other people's expertise and knowledge that will give your app extra functionality and features - fast. In this filtered view of our product catalog you will only find .NET compatible products, these products include both .NET Components and .NET Controls as .NET downloads for you to try and buy.

What is a .NET Control? A .NET Control has a visual aspect and can be used on a form or Web page to control the behavior of the user interface, so the user of the app can use a .NET UI Control to: enter data, click on a button, select from items displayed on a drop down list, draw a chart or graph based on data that they have entered into a .NET datagrid control etc.

What is the difference between a .NET Component and a .NET Control?

A .NET Component does not always have to have a visual interface, for example a .NET Component could work behind the scenes on a server and be used to calculate the tax due on an invoice for goods sold to a customer or to create a PDF version of that invoice and then email it to the customer's email address. .NET Controls are User Interface (UI) controls and they are a subset of .NET Components and as such all .NET Controls are therefore .NET Components, however, the reverse is not true, a .NET Component is not also a .NET Control, as a .NET Component does not have to have a visual or visible interface and it does not have to appear on a Windows form, Web Form or Web page as part of the UI.

In this .NET Components marketplace you will find both .NET Controls and .NET Components - available as commercial grade, quality .NET software component products.
