{
    // Use a function to validate the row's values.
    // If the function returns true, end the edit;
    // otherwise cancel it.
    if(ValidateRow(row))
        row.EndEdit();
    else
        row.CancelEdit();
}

private bool ValidateRow(DataRow thisRow)
{
    bool isValid = true;
    // Insert code to validate the row values.
    // Set the isValid variable.
    return isValid;
}
