Windows Forms Inheritance

Visual Studio .NET 2003

On some occasions, you may decide that a project calls for a form similar to one that you have created in a previous project. Or you may want to create a basic form with settings such as a watermark or certain control layout that you will then use again within a project, with each iteration containing modifications to the original form template. Form inheritance enables you to create a base form and then inherit from it and make modifications while preserving whatever original settings you need.

You can create subclassed forms in code or by using the Visual Inheritance picker.
