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)

'Declaration
Public Sub AcceptChanges
'Usage
Dim instance As DataRow

instance.AcceptChanges
public void AcceptChanges ()
public function AcceptChanges ()
Not applicable.

Exception typeCondition

RowNotInTableException

The row does not belong to the table.

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.

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 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
