DataTable.RejectChanges Method

Rolls back all changes that have been made to the table since it was loaded, or the last time AcceptChanges was called.

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

'Declaration
Public Sub RejectChanges
'Usage
Dim instance As DataTable

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

When RejectChanges is called, any DataRow objects that are still in edit-mode cancel their edits. New rows are removed. Rows with the DataRowState set to Modified or Deleted return back to their original state.

The following example makes several changes to a DataTable, but rejects the changes by invoking the RejectChanges method.

Private Sub ShowRejectChanges(table As DataTable)
    ' Print the values of row 1, in the column named "CompanyName."
    Console.WriteLine(table.Rows(1)("CompanyName"))

    ' Make Changes to the column named "CompanyName."
    table.Rows(1)("CompanyName") = "Taro"

    ' Reject the changes.
    table.RejectChanges()

    ' Print the original values:
    Console.WriteLine(table.Rows(1)("CompanyName"))
End Sub
