Remarks

The IFilterResolutionService.CompareFilters method is part of the IFilterResolutionService interface, which is specific to how a control uses device filters in a designer environment. When controls are parsed or persisted in the designer environment outside the context of a browser request, the IFilterResolutionService provides a way to determine if the current control is affected by a named filter and whether a named filter is part of a specific device-filter hierarchy.
