TemplateControl.IFilterResolutionService.CompareFilters Method

Other Versions

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Namespace: System.Web.UI
Assembly: System.Web (in System.Web.dll)

Syntax

C++

int IFilterResolutionService.CompareFilters(
	string filter1,
	string filter2
)

Parameters

filter1: Type: System.String
A device filter name.

filter2: Type: System.String
A device filter name.

Return Value

Type: System.Int32
1, if filter1 is a parent of filter2; -1, if filter2 is a parent of filter1; otherwise, 0, if there is no parent/child relationship between filter1 and filter2.

Implements

IFilterResolutionService.CompareFilters(String, String)

Remarks

The 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.
