Hi, We have a database that we’re trying to transition from v13 to v15. It originally began in v3.5 and has been updated as 4D has advanced.
We have some detail forms which have variable fields where information is entered that is used for queries and a subform which displays the query results.. The list form that is attached to the subform area has code which executes each time an ‘on display detail’ event occurs. In v13 we could type some info into one of the variable fields and then tab out to execute the query and the displayed records would execute the ‘on display detail’ event once for each of the displayed records. With v15 we are finding that the ‘on display detail’ events are being generated many, many more times than they were with v15. In this specific case, each time a letter is typed into the entry variable the displayed info refreshes. Net effect is a very, very sluggish user interface. In one case, the display detail events are being triggered so frequently that the form is barely usable. We have restricted the activated events for the forms to the minimum we can. We are also seeing some things which are confusing, e.g. each time we type a character into a data entry variable the entire form redraws, but if we turn off the ‘on clicked’ event then the redraws stop. It seems that form events are propagating very differently in v15 compared to v13. Can anyone provide any insight, pointers to docs, … ? We’re using a subform for display because we want to display 2 lines of data for each record and in some cases we include graphic elements which behave like buttons so that the user can bring up more info about specific components of the displayed information. Any insight would be appreciated. Thanks.
