Module 09-DynamicControls

Learning Objectives

• create and work with extended controls
• generate new controls dynamically and be able to interact with them
• work with .NET arrays

Module Description:

Summary

User Interface and Interaction

In particular

1. The U.I. should include a button with which the user can create a new box, and display it on screen.
2. The boxes are automatically numbered in the order in which they are created and displayed in an orderly fashion.
3. The U.I. should also include facilities to delete one of the boxes by specifying its number. The point of this is to access the box indirectly by its number rather than directly by clicking on it.
4. When new boxes are created after boxes have been deleted, the positions left empty by the deleted boxes should be filled in order in a visible way. E.g. in the example, delete one a few of the middle boxes and then add more boxes.
5. There should be no limit to the number of boxes that can be created and deleted.

Implementation Details

1. The boxes are extended Button controls called "Box" which simply contain the number representing their position.
2. The boxes should be dynamically generated at run-time instead of statically at compile-time.
3. The boxes should be kept in an array.
