If the data for a DataWindow is not coming from a database or a Web service data source (that is, the data source was defined as External in the DataWindow wizard), you can use these methods to import data into the DataWindow control:
ImportClipboard
ImportFile
ImportString
You can also get data into the DataWindow by using the SetItem method or by using a DataWindow expression.
For more information on the SetItem method and DataWindow expressions, see “Manipulating data in a DataWindow control”.
