My suggestion is to avoid creating a separate refresh method if possible, instead you should put the refresh code where it belongs, namely in the refresh event if each object, sometimes together with Nodefault-code-Dodefault. This way to design also encapsulates all the objects, so it's easy to copy or move them to other forms and pages, without having to change any code.

Earlier I used to create a seperate Update function, but I found that this caused refresh to be called more than once for many objects.

>>Without more information, such as the code itself or what the code in the refresh event is doing exactly, it is really difficult to offer anything meaningful in the way of help. 1000 objects on a single form seems like quite a few, depends on what you're doing with them though. 1000 lines is a lot different than 1000 grids for instance.
