Gets a list of user control properties that the output cache uses to vary the user control.
Assembly: System.Web (in System.Web.dll)
The following code example demonstrates how the PartialCachingAttribute(Int32, String, String, String) constructor can be applied to a user control. In the example, the constructor is used to indicate that the user control can be cached, to specify the caching duration as 20 seconds, and to specify a control named state for which the user control output will be varied.
// Set the PartialCachingAttribute.Duration property to // 20 seconds and the PartialCachingAttribute.VaryByControls // property to the ID of the server control to vary the output by. // In this case, it is state, the ID assigned to a DropDownList // server control. [PartialCaching(20, null, "state", null)]
