Overriding Properties 

ASP.NET mobile Web pages can customize the property values of their controls based on the capabilities of the requesting device. For example, in your application, you might use a Label control to display long text on one set of devices and abbreviated text on another. Each control provides a set of properties that the application can override on a per-device basis.

To override particular properties of a control, you must first define device filters. Apply the device filters to the control to specify the set of devices for which you want to define custom property values. Property override values can be edited only for the current device filter. Therefore, you must select the filter that you want to use to override property values, and set it as the current filter. After you select the device filter, you set the property override values for that filter. To set property override values for additional filters, select each filter in turn and specify the custom property values for that filter.

Procedures

  3. If there are no device filters defined, do the following:

    1. Click Edit. The Applied Device Filters dialog box is displayed.

    2. In the Applied Device Filters dialog box, click Edit to display the Device Filter Editor dialog box.

    3. Define one or more device filters for the control.

  4. If device filters are defined but not currently applied, apply device filters by doing the following:

    2. Apply one or more device filters to the control.
