public void AcceptChanges();

member this.AcceptChanges : unit -> unit

Public Sub AcceptChanges ()

Examples

The following example tests each table for errors. If the table's errors can be reconciled (by passing it to an undefined function), AcceptChanges is called; otherwise, RejectChanges is called.

private void AcceptOrReject(DataTable table)
{
 // If there are errors, try to reconcile.
 if(table.HasErrors)
 {
 if(Reconcile(table))
 {
 // Fixed all errors.
 table.AcceptChanges();
 }
 else
 {
 // Couldn'table fix all errors.
 table.RejectChanges();
 }
 }
 else
 {
 // If no errors, AcceptChanges.
 table.AcceptChanges();
 }
}

private bool Reconcile(DataTable thisTable)
{
 foreach(DataRow row in thisTable.Rows)
 {
 //Insert code to try to reconcile error.

 // If there are still errors return immediately
 // since the caller rejects all changes upon error.
 if(row.HasErrors)
 return false;
 }
 return true;
}

Private Sub AcceptOrReject(table As DataTable)
 ' If there are errors, try to reconcile.
 If (table.HasErrors) Then
 If (Reconcile(table)) Then
 ' Fixed all errors.
 table.AcceptChanges()
 Else
 ' Couldn'table fix all errors.
 table.RejectChanges()
 End If
 Else
 ' If no errors, AcceptChanges.
 table.AcceptChanges()
 End If
 End Sub
 
Private Function Reconcile(thisTable As DataTable) As Boolean
 Dim row As DataRow
 For Each row in thisTable.Rows
 'Insert code to try to reconcile error.

 ' If there are still errors return immediately
 ' since the caller rejects all changes upon error.
 If row.HasErrors Then
 Reconcile = False
 Exit Function
 End If
 Next row
 Reconcile = True
 End Function

Remarks

When AcceptChanges is called, any DataRow object still in edit mode successfully ends its edits. The DataRowState also changes: all Added and Modified rows become Unchanged, and Deleted rows are removed.

The AcceptChanges method is generally called on a DataTable after you attempt to update the DataSet using the DbDataAdapter.Update method.
