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.

[C#]
```
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.

[C#]
```
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 for the following expression.

[C#]
```
(MobileDeviceCapabilities)Page.Request.Browser
```

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

[C#]

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

protected WmlFormAdapter FormAdapter
{
    get
    {
        return ((WmlFormAdapter)FormAdapter);
    }
}
