| Store | Creates a persistent "scratch pad" on the given page to store and manipulate data. |
|
|
The Store method on a Page object creates a persistent scratch pad to store and manipulate data. In contrast with the Scratch method, the scratch pad created by the Store method is not reset on server rebuilds.
To create a locally scoped scratch pad that is not attached to a Page object, use the newScratch function.
