Hi Don,

Just a crazy thought here...

but could you take the controls from the pageframe, place them in a container, and then instantiate the container behind the scenes at some (earlier) point in time, WITHOUT the container being visible?

The basic idea is, when your user selects page 3, you would position the container on the page and make it visible -- but the textboxes have already "done their thing" (or some part of it) and the page *appears* to display faster. Also, since the control isn't visible, there's no *visual* redraw of the control happening, so it should be a bit faster than your current approach.

Like I said -- just a crazy thought --

>I have a form that contains a pageframe with a large number of controls on each page. Page 3 of the pageframe contains 96 textboxes which are subclassed to present computed data. The refresh method of the custom textbox contains the following code:

After the first calculation the page works reasonable fast as we skip through the records. I have played with lockscreen but have not been able to find a way to speed up the initial refresh. The page has
