C# Simplified, part 7: Working with WinForm Controls - Working with Checkboxes

(Page 2 of 6 )

Checkboxes enable you to select more than one item at a time. This control is widely used in all applications. The moment you click on an item, a tick mark appears on the control. The tick mark will disappear if you click it again. Listing 7.2 illustrates this control:

Listing 7.2

001: using System;
002: using System.Drawing;
003: using System.Windows.Forms;
004:
005: public class MyCheckbox:Form
006: {
007:   CheckBox c1 = new CheckBox();
008:   CheckBox c2 = new CheckBox();
009:   CheckBox c3 = new CheckBox();
010:
011:   MyCheckbox()
012:   {
013:     c1.Text = "Football";
014:     c2.Text = "BasketBall";
015:     c3.Text = "Swimming";
016:
017:     c1.Location = new Point(50,40);
018:     c2.Location = new Point(50,60);
019:     c3.Location = new Point(50,80);
020:
021:     this.Controls.Add(c1);
022:     this.Controls.Add(c2);
023:     this.Controls.Add(c3);
024:
025:     this.Text = "CheckBox Control Demo";
026:   }
027:
028:   public static void Main()
029:   {
030:     MyCheckbox mychk = new MyCheckbox();
031:     Application.Run(mychk);
032:   }
033: }
