member this.AcceptChanges : unit -> unit
Public Sub AcceptChanges ()

Exceptions

RowNotInTableException

The row does not belong to the table.

Examples

The following example first creates a new DataTable with one column, and then creates a single DataRow. As the DataRow is created, added, modified, and deleted, its RowState is printed.

private void DemonstrateAcceptChanges()
{
    //Run a function to create a DataTable with one column.
    DataTable table = MakeTable();
    DataRow row;

    // Create a new DataRow.
    row = table.NewRow();
    // Detached row.
    Console.WriteLine("New Row " + row.RowState);

    table.Rows.Add(row);
    // New row.
    Console.WriteLine("AddRow " + row.RowState);

    table.AcceptChanges();
    // Unchanged row.
    Console.WriteLine("AcceptChanges " + row.RowState);

    row["FirstName"] = "Scott";
    // Modified row.
    Console.WriteLine("Modified " + row.RowState);

    row.Delete();
    // Deleted row.
    Console.WriteLine("Deleted " + row.RowState);
}

private DataTable MakeTable()
{
    // Make a simple table with one column.
    DataTable table = new DataTable("table");
    DataColumn fnameColumn = new DataColumn(
        "FirstName", Type.GetType("System.String"));
    table.Columns.Add(fnameColumn);
    return table;
}

Private Sub DemonstrateAcceptChanges()
    ' Run a function to create a DataTable with one column.
    Dim table As DataTable = MakeTable()
    Dim row As DataRow 
 
    ' Create a new DataRow.
    row = table.NewRow()
    ' Detached row.
    Console.WriteLine("New Row " & row.RowState)
 
    table.Rows.Add(row)
    ' New row.
    Console.WriteLine("AddRow " & row.RowState)
 
    table.AcceptChanges()
    ' Unchanged row.
    Console.WriteLine("AcceptChanges " & row.RowState)
 
    row("FirstName") = "Scott"
    ' Modified row.
    Console.WriteLine("Modified " & row.RowState)
 
    row.Delete()
    ' Deleted row.
    Console.WriteLine("Deleted " & row.RowState)
 End Sub
 
 Private Function MakeTable()As DataTable
    ' Make a simple table with one column.
    Dim table As New DataTable("table")
    Dim fnameColumn As New DataColumn( _
        "FirstName", Type.GetType("System.String"))
    table.Columns.Add(fnameColumn)
    MakeTable = table
 End Function

Remarks

When invoking AcceptChanges, the EndEdit method is implicitly called to end any edits. If the RowState of the row was Added or Modified, the RowState becomes Unchanged. If the RowState was Deleted, the row is removed.

See the BeginEdit method for more information.

The DataTable class also has an AcceptChanges method which affects changes made to the whole table. For more information and a code example that demonstrates how to accept and reject changes to individual data rows, see AcceptChanges and RejectChanges.
