Both the DataRow and DataTable classes have AcceptChanges methods. Calling AcceptChanges at the DataTable level causes the AcceptChanges method for each DataRow to be called. Similarly, invoking AcceptChanges on the DataSet causes AcceptChanges to be called on each table within the DataSet. In this manner, you have multiple levels at which the method can be invoked. Calling the AcceptChanges of the DataSet enables you to invoke the method on all subordinate objects (for example, tables and rows) with one call.

When you call AcceptChanges on the DataSet, any DataRow objects still in edit-mode end their edits successfully. The RowState property of each DataRow also changes; Added and Modified rows become Unchanged, and Deleted rows are removed.

If the DataSet contains ForeignKeyConstraint objects, invoking the AcceptChanges method also causes the AcceptRejectRule to be enforced.

Note:
AcceptChanges and RejectChanges only apply to DataRow related changes (that is, Add, Remove, Delete, and Modify). They are not applicable to schema or structural changes.

The following example adds a DataRow to a DataTable in a DataSet. The AcceptChanges method is then called on the DataSet, which cascades to all DataTable objects that it contains.

Private Sub AcceptChanges()
   Dim myDataSet As DataSet
   myDataSet = new DataSet()

   ' Not shown: methods to fill the DataSet with data.
   Dim t As DataTable

   t = myDataSet.Tables("Suppliers")

   ' Add a DataRow to a table.
   Dim myRow As DataRow
   myRow = t.NewRow()
   myRow("CompanyID") = "NWTRADECO"
   myRow("CompanyName") = "NortWest Trade Company"

   ' Add the row.
   t.Rows.Add( myRow )

   ' Calling AcceptChanges on the DataSet causes AcceptChanges to be
   ' called on all subordinate objects.
   myDataSet.AcceptChanges()
End Sub

private void AcceptChanges()
{
   DataSet myDataSet;
   myDataSet = new DataSet();

   // Not shown: methods to fill the DataSet with data.
   DataTable t;
   t = myDataSet.Tables["Suppliers"];

   // Add a DataRow to a table.
   DataRow myRow;
   myRow = t.NewRow();
   myRow["CompanyID"] = "NWTRADECO";
   myRow["CompanyName"] = "NortWest Trade Company";

   // Add the row.
   t.Rows.Add( myRow );

   // Calling AcceptChanges on the DataSet causes AcceptChanges to be
   // called on all subordinate objects.
   myDataSet.AcceptChanges();
}
