How to populate a custom field in the table view

Hi Forum,

I am a newbie to Web UI... Could any one help me with the syntax and way to achieve the below functionality.

I have a table view in which BTAdminI records are populated. I have to add a new column to that table view which needs to populated at runtime.

To achieve this i have enhanced the structure of BTAdminI and appended this new custom field and enabled this field in the configuration.

I need to show the concatenated value of column1 and column2 in the newly displayed custom field/coulmn3.

Where can i write the code and what is the sytax to populate data in the new column.

Thanks for your help in advance.

Regards

M.C
