Adapter Interaction with ASP.NET

ASP.NET mobile device adapters for a specified mobile device can interact with other adapters, controls, and pages through the following properties:

• A control adapter can access its associated control through the Control property, defined in the ControlAdapter base class.

  Note

  Each control adapter class must define a new, strongly typed Control property. For example, an adapter for the Label control would include the following code.

  protected new Label Control
  {
      get
      {
          return (Label)base.Control;
      }
  }
  

• A control adapter can access its associated page through the Page property, defined in the ControlAdapter base class.

  Note

  A page adapter class must implement a read/write Page property. This is an implementation requirement of the IPageAdapter interface. The following is an example of such code.

  private MobilePage _page;
  public override MobilePage Page
  {
      get
      {
          return _page;
      }
      set
      {
           _page = value;
      }
  }
  

• A control adapter can access the current device capabilities through the Device property, defined in the ControlAdapter base class. This property is a short form of the following expression.

  (MobileDeviceCapabilities)Page.Request.Browser
  

• For convenience, the device-specific control adapter base class should expose properties that grant access to the page adapter and the form adapter. The following is an example of such code.

  protected WmlPageAdapter PageAdapter
  {
      get
      {
          return ((WmlPageAdapter)Page.Adapter);
      }
  }
  
  protected WmlFormAdapter FormAdapter
  {
      get
      {
          return ((WmlFormAdapter)FormAdapter);
      }
  }
