access to other records in tvirtualtable
Posted: Thu 12 Mar 2009 11:02
Hi, I need to access data in non-current records in a TVirtualTable. how can I do that?
example: user inserts record and, while being in dsinserted mode, the cumulative sums under the current record have to be online updated, if the user enters a value in the field, that is to be summed.
Posting the record, scrolling through the other records and coming back is not possible - the inserted record has to be in dsinsert mode, not in dsedit (for example - because the required fields are not all set yet). and, the code would be crazy (full of sucking bookmarks, disablecontrols etc.)
is there a way to access (read/modify) fields in other records of a tvirtualtable while staying on an other one? something like duplicating a cursor to the data or (better) direct array-like access?
thanks, Ludek.
