Is it possible to change the height of a band dynamically? My intention is to create an invoice by grouping the lines by sales order. Within it, place a Text Field. If an invoice line comes from an order -> show the order reference. If an invoice line does not come from an order -> the height of the band (for that line) should be 0. It is not enough for me to just hide the Text field by acting on "Print when" [the height of the band is the same busy - even if the text is not present].
