Class Grid

java.lang.Object
  org.apache.tapestry.corelib.components.Grid

All Implemented Interfaces:

GridModel

@SupportsInformalParameters
public class Grid
extends Object
implements GridModel

A grid presents tabular data. It is a composite component, created in terms of several sub-components. The sub-components are statically wired to the Grid, as it provides access to the data and other models that they need.

A Grid may operate inside a Form. By overriding the cell renderers of properties, the default output-only behavior can be changed to produce a complex form with individual control for editing properties of each row. This is currently workable but less than ideal -- if the order of rows provided by the GridDataSource changes between render and form submission, then there's the possibility that data will be applied to the wrong server-side objects.
