Examples

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 and to specify the parameter upon which the cache entry is dependent.

// Set the PartialCachingAttribute.Duration property to
// 20 seconds and the PartialCachingAttribute.VaryByParams
// property to ctlSelect.country, the full name of the form 
// POST parameter generated by the country DropDownList control.
[PartialCaching(20, "ctlSelect.country", null, null)]
public partial class ctlSelect : UserControl

' Set the PartialCachingAttribute.Duration property to
