The data grid adds methods to the prototype of the Array class so that each Array object conforms
to the DataProvider API (see DataProvider.as in the Classes/mx/controls/listclasses folder). Any
array that is in the same frame or screen as a data grid automatically has all the methods

In a DataGrid component, you specify fields for display in the
If you don't define the column set (by setting the
DataGrid.addColumn()
been set, the data grid generates columns for each field in the data provider's first item, once that
item arrives.
Any object that implements the DataProvider API can be used as a data provider for a data grid
(including Flash Remoting recordsets, data sets, and arrays).
Use a grid's data provider to communicate with the data in the grid because the data provider
remains consistent, regardless of scroll position.
Example
The following example creates an array to be used as a data provider and assigns it directly to the
property:
dataProvider
grid.dataProvider = [{name:"Chris", price:"Priceless"}, {name:"Nigel",
price:"cheap"}];
The following example creates a new Array object that is decorated with the DataProvider API. It
uses a loop to add 20 items to the grid:
for
myDP = new Array();
for (var i=0; i<20; i++)
myDP.addItem({name:"Nivesh", price:"Priceless"});
list.dataProvider = myDP
