I want show data from two table in a single listgrid.
Is it possibile?
EDIT: are two istance of two different table.
addData(Record newRecord)
Perform a DataSource "add" operation to add new records to this component's DataSource.
This is a method to add more data in a listgrid.
There are two more variants available look this link : http://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/widgets/grid/ListGrid.html
