The DataGrid control is one of the most popular controls in the Flex SDK. It displays relational data in the form of rows and columns, and enables the user to easily scroll through and select data. In addition, the DataGrid can be made editable, enabling the user to edit multiple rows of data in batches instead of having to navigate to a data entry form interface for each row he wants to modify.
NOTE
The Flex 4 SDK does not include Spark versions of the DataGrid component and its advanced extensions, AdvanceDataGrid and OlapDataGrid. Adobe intends to create Spark versions in a later revision of the SDK, but for now you should use the MX versions.
