Hi,
You can write a query and attach it to your TextBox to get the desired result.
Also based on the selection in one textbox you can refresh or put the value in other TextBox in single time.
You can put your mouse on a particualt textbox and press ALT+SHIFT+F2.
This will provide you the options available for FMS.
Hope it helps.
Thanks & Regards
