I have change the script as per below based on your suggestion. The DataGrid does displays the row of data but it's without the CheckBox.
Not sure why it's not working.
Please Help. Thanks
I did have a look at the URL site with VB format script and compared it with my C# format script. Logically it looks very similiar. The VB script end result shows the DataGrid with CheckBox but not my version. I am very puzzled.
