DataRow.AcceptChanges Method (System.Data)

.NET Framework Class Library

DataRow..::.AcceptChanges Method

Commits all the changes made to this row since the last time AcceptChanges was called.

Namespace: System.Data
Assembly: System.Data (in System.Data.dll)

Syntax

Visual Basic (Declaration)

Public Sub AcceptChanges

Visual Basic (Usage)

Dim instance As DataRow

instance.AcceptChanges()

public void AcceptChanges()

Visual C++

public:
void AcceptChanges()

JScript

public function AcceptChanges()

Exceptions

Exception	Condition
RowNotInTableException	The row does not belong to the table.

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 (ADO.NET).

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.

Visual Basic

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 DataTable = New DataTable("table")
    Dim fnameColumn As DataColumn = New DataColumn( _
        "FirstName", Type.GetType("System.String"))
    table.Columns.Add(fnameColumn)
    MakeTable = table
 End Function

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;
}
