GridDeck Function

GridDeck is a Deck Generator utility pattern which enables the listing of database records in a WML table.  GridDeck scopes a GridCard function based on the GridCard Card Generator pattern.

A Deck Generator function based on the GridDeck pattern may be extended by a Grid Event Handler or a Jump function and one or more additional Card Generator functions. 

Example:

MyGridDeck is a FNC GridDeck
replaces VW
...by VW		 UIBasic.Grid
MyEntity.Fetch
MyGridDeck.GridCard name NME List MyEntities
local view VW
...for VAR
...omit FLD		 MyEntity.Fetch
OmitGridFields
FieldA

In the example above, all fields but FieldA are omitted from being displayed in the Grid.  This is because most WAP devices only provides limited space for the displayment of data.

The GridDeck pattern receives the key fields of the UIBasic.Grid view as input parameters.  This input determines the start position of the data fetch on the view specified for the Grid function.
