Architecture

• Most controls are inherited from the built-in
  ASP.NET controls, except when
• The base control is poorly implemented
• It doesnt make sense to create the control
• (ie. Validators)
• Ajax is built directly into the controls
• Serializes method calls to client side objects
  instead of re-rendered markup. Keeping state on
  the client.
• Advanced controls are built on top of the basic
  building blocks
• Dogfooding base controls increases product
  quality

Key Point
Gaia serializes method calls to the client
instead of innerHTML

Best practice DOM/CSS

• All extended controls are written using best
  practice DOM/CSS.
• Custom XhtmlTextWriter ensures 100 valid markup

• Source code included

• Fully documented

Debugging

• Server is extremly easy to debug directly in
  Visual Studio.NET
• Client can sometimes be harder to debug and
  firebug is a must.
• Read XHR responses and requests
• DOM inspection
• Javascript debugging
• What usually goes wrong?
• Control not in Controlcollection
• Control doesnt have ID
• ReRendering Abuse
• Aspects collision

Extending Gaia

• Inheritance
• GaiaControl, GaiaWebControl
• Composition
• Autocompleter, DateTimePicker, Accordion
• Container Composition
• Window, ExtendedPanel
• Custom Extension w/ javascript file
• Calendar, InPlaceEdit, Toolbar

36
Inheritance

• Inherit from any control that implements
  IAjaxControl

37
Composition
38
Container Composition

• Inherit from HybridPanelBase
• Add composite controls to CompositionControls
  collection

39
Custom Extensions

• Easily create custom extension controls
• Attach .js files that will be dynamically
  included
• Map Server To Client methods and viceversa
• Managed XhtmlTextWriter for ensured xhtml
