void onPreviewShown(PreviewShownEvent event)
grid is populated with a
new set of data for the user to preview before commit. This notification occurs after the user has uploaded a new
data file, the data has been processed on the server, and the preview grid populated with the data ready for committing.
Developers may use this notification to examine or modify the data set to be uploaded. The ListGrid.data object will be populated with the array of uploaded
records, and standard grid APIs such as ListGrid.getRowErrors(), ListGrid.setEditValue(), etc
may be used to interact with this data.
Note that developers wishing to manipulate the uploaded data can also do
this on the server side when user hits the commit button to submit the data to the uploadDataSource. This can be achieved by setting the
uploadOperation to call a custom "add" type operation on the target dataSource.
