Dynamic Report Parameters

bukowzky

Hi everyone, i'm brand new with BIRT and i hope someone could help me.
I´m generating an inventory report wich is based on 2 basic report parameters that comes from a dataset (select distinct prod_id, product from products) and diplayed as combo boxes, my fist parameter is "Initial Item" and the second one "Final Item", so the information that i display is the inventory level from my initial product to my final product in a list element cause it contains subreports:

What i want to do is that the second parameter (combo box) takes the value from my firts combo box once it is selected. to help end user to make its selection easier, because it's a large item catalog. so if i scroll the items in the combo box once in my first selection, I would only scroll down from my first selection to my second selection and not all the entire items in the combo box.

i hope u could help me with this or showing me how can i do something similar.

thank you very much.

You would either need to customize the parameter dialog in the viewer to do this, or use your own external parameter dialog and pass the values into the birt viewer on submit.
