After calling CancelEdit, all changes to the row are rolled back. You can also roll back changes by calling RejectChanges on the parent DataTable.

The following example edits a row in a DataView. The CancelEdit method is called to cancel the changes if the validation fails.

private void EditDataRowView(DataRowView rowView, 
    string columnToEdit) 
{
    rowView.BeginEdit();
    rowView[columnToEdit] = textBox1.Text;

    // Validate the input with a function.
    if (ValidateCompanyName(rowView[columnToEdit]))
        rowView.EndEdit();   
    else
        rowView.CancelEdit();
}
 
private bool ValidateCompanyName(object valuetoCheck) 
{
    // Insert code to validate the value.
    return true;
}
