onPreviewShown
Notification method fired when thegrid
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 asListGrid.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 theuploadOperation
to call a custom"add" type operation
on the target dataSource.- Parameters:
