Prototyping for HCI Spring 2004 (Week 10) Jorge A. Toro

The Language Custom Controls

Custom Controls • Controls are graphic objects that represent the properties or operations of other objects • VB.NET Allows you to create your own set of controls

Custom Controls • There are different kinds of custom controls • We will focus in the simplest ones • You can add any controls you want similar to what you do when creating forms

Example • Custom label

Custom Controls

Two sections Get What the property returns if someone tries to read it Set What the property receives if someone tries to write in it Adding properties Public Property Title() Get Return label1.text EndGet Set(ByVal Value) label1.text = Value EndSet EndProperty

Using the Control • The custom control will appear in the control toolbox. • Drag the control over the form just as any other control. • Warning! You need to compile the project first before putting the control in.

Using the control • The properties window will show the properties you defined for the control as well as others that come by default
