DataSet.GetChanges Method (DataRowState)
Assembly: System.Data (in system.data.dll)
One of the DataRowState values.
Return ValueA filtered copy of the DataSet that can have actions performed on it, and subsequently be merged back in using Merge. If no rows of the desired DataRowState are found, the method returns a null reference (Nothing in Visual Basic).
The GetChanges method is used to produce a second DataSet object that contains only the changes introduced into the original. Use the rowStates argument to specify the type of changes the new object should include.
This returned copy is designed to be merged back in to this original DataSet. Relationship constraints may cause parent rows marked Unchanged to be included. If no rows of the desired DataRowState are found, the GetChanges method returns a null reference (Nothing in Visual Basic).
