DataTable.GetChanges Method (DataRowState)

Gets a copy of the DataTable containing all changes made to it since it was last loaded, or since AcceptChanges was called, filtered by DataRowState.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)
member GetChanges : 
        rowStates:DataRowState -> DataTable

Parameters

rowStates
Type: System.Data.DataRowState

One of the DataRowState values.

Return Value

Type: System.Data.DataTable
A filtered copy of the DataTable that can have actions performed on it, and later be merged back in the DataTable 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 DataTable 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.

Relationship constraints may cause unchanged parent rows to be included.
