Creating the Inherited Form
Topic Objective
To explain how to create an inherited form.
Lead-in
Creating an inherited form is simple.
After you have designed your base form and built the solution, you are ready to begin deriving forms. To do this, you simply add a new item to the project by clicking Inherited Form in the Add New Item window. This will run the Inheritance Picker for you.
When inheriting from a base Windows Form, consider the following guidelines carefully:
■ Ensure that the base form is as complete as possible.
Make any last minute changes to the base form before inheriting from it.
■ Reference the assembly.
If the base form is not in the same project, you must make a reference to the appropriate assembly.
■ Create a new Inherited Form item.
Add a new Inherited Form item to your project, selecting the base form in the Inheritance Picker dialog box. A list of available base forms is shown, and you can browse for other assemblies.
■ Change control properties where necessary.
You can programmatically change public and protected controls, and you can use the Properties window of the Windows Forms Designer for a derived form. Private controls cannot be altered outside of the base form.
■ Override methods or events as required.
If methods or event handlers have been marked as overridable, you can implement your own code in the derived form.
