Example Application: Movie Review

Description

A domain up/down control is a spin button that is used to navigate a list of values or objects. This application shows how to visit the members of an array, retrieve its members and display their values.

Practical Learning: Introducing the Domain Up-Down Control

1. Start a new Windows Application and name it MovieReview1
2. Right-click each of the following pictures and paste them in the MovieReview1\MovieReview1\bin\Debug folder of the current project
    
3. Design the form as follows:
    

   

   Control	Text	Name	Other Properties
   Label	Title:
   DomainUpDown		dudTitles	TextAlign: Center UpDownAlign: Left
   Label	Director:
   TextBox		txtDirector
   Label	Cast of Characters
   Label	© Year
   TextBox		txtYearReleased	TextAlign: Right
   Label	Rating:
   TextBox		txtRating
   ListBox		lbxCastMembers
   Label	Length:
   TextBox		txtLength
   PictureBox		pbxImage
   Button	Close	btnClose

4. In the Solution Explorer, right-click Form1.cs and click Rename
5. Type MovieReview.cs and press Enter
6. Double-click an unoccupied area of the form
7. Return to the form
8. On the form, double-click the domain up-down control
9. Implement its events as follows:
