How to go through all inventory entries automatically in a voucher

I have designed a TDL that automatically imports inventory entries into a voucher from an xml file. My only problem is that i am not able to display all the details on the main screen. That is, only the Stock Item Name, Quantity, and Inclusive Rate is imported and displayed on the voucher screen. However, when we click on any stock item, the Batch allocations subform contains all the necessary details like rate, amount, etc. But i am unable to import it onto the main voucher screen without having to manually click on each stock item.

Is there a way by which i can automatically go through all the inventory entries so that all the details appear on screen, without the user having to manually click through each of them?

Hope my query is clear...
