Description

Use this property and the SourceVersion property when you are submitting pending changes to the database and you want to validate the version of the data in the target row. To return a value from a particular column in the database, set the SourceColumn property to the name of the column. If the Direction property is set to Input, the value is taken from the DataSet instead of the database. If the Direction property is set to Output, the value is taken from the database.
