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

[Visual Basic]
Public Sub RejectChanges()
[C#]
public void RejectChanges();
[C++]
public: void RejectChanges();
[JScript]
public function RejectChanges();

Remarks

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.

Example

[Visual Basic, C#] The following example makes several changes to a DataTable, but rejects the changes by invoking the RejectChanges method.

[Visual Basic] 
Private Sub ShowRejectChanges(myTable As DataTable)
    ' Print the values of row 1, in the column named "CompanyName."
    Console.WriteLine(myTable.Rows(1)("CompanyName"))
    ' Make Changes to the column named "CompanyName."
    myTable.Rows(1)("CompanyName") = "Taro"
    ' Reject the changes.
    myTable.RejectChanges()
    ' Print the original values:
    Console.WriteLine(myTable.Rows(1)("CompanyName"))
End Sub

[C#] 
private void ShowRejectChanges(DataTable myTable){
   // Print the values of row 1, in the column named "CompanyName."
   Console.WriteLine(myTable.Rows[1]["CompanyName"]);
   // Make Changes to the column named "CompanyName."
   myTable.Rows[1]["CompanyName"] = "Taro";
   // Reject the changes.
   myTable.RejectChanges();
   // Print the original values:
   Console.WriteLine(myTable.Rows[1]["CompanyName"]);
}
