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)

public void RejectChanges ()
public void RejectChanges ()
public function RejectChanges ()

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 void ShowRejectChanges(DataTable table)
{
    // 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"]);
