Parameters

region
Type: System::String^

The name of the region for which the specified item or region operations can trigger cache notifications.

filter
Type: Microsoft.ApplicationServer.Caching::DataCacheOperations

The type of cache operation(s) that will trigger cache notifications.

clientCallback
Type: Microsoft.ApplicationServer.Caching::DataCacheNotificationCallback^

The name of the method you want to invoke when these notifications occur.

Return Value

Type: Microsoft.ApplicationServer.Caching::DataCacheNotificationDescriptor^

A DataCacheNotificationDescriptor object used to identify the cache notification callback.

Use the DataCacheOperations enumeration in the filter parameter to specify what type of item operations you want to trigger cache notifications. Select more than one enumeration by separating the enumerations with the binary OR operator to perform a bitwise OR. To do this, use the | character in C#, and the Or operator in Visual Basic.

The clientCallback method you invoke with the cache notification must accept the same parameters as the DataCacheNotificationCallback delegate.
