private void AcceptOrReject(DataRow row)
{
    // 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;
}

 Private Sub AcceptOrReject(ByVal row As DataRow)
    ' Use a function to validate the row's values.
    ' If the function returns true, end the edit; 
    ' otherwise cancel it.
    If ValidateRow(row) Then
       row.EndEdit()
    Else
       row.CancelEdit()
    End If
End Sub
 
Private Function ValidateRow(ByVal row As DataRow) As Boolean
    Dim isValid As Boolean
    ' Insert code to validate the row values. 
    ' Set the isValid variable.
    ValidateRow = isValid
End Function
