Does anybody knows how to create a list like the visual studio propeties list?

I think you are referring to the PropertyGrid in Visual Studio. You can look up the property grid class to see how it works. http://msdn.microsoft.com/library/default.asp?url=/library/enus/cpref/html/frlrfSystemWindowsFormsPropertyGridClassTopic.asp In short you can create any object with public properties and set propertyGrid.SelectedObject to an instance of this object. The properties of your class will automatically be displayed in the property grid and you can view as well as set them.
