May be you can use scrollable container instead of growing form? If so, use Alexander Grigoriev class here in Downloads section.

>Wonder if I have painted myself in a corner. Have created a "scrolling, growing" "dialog" (form) to present users with series of questions (did this instead of a "wizard" approach of numerous mini-forms). As they answer one question, another set of controls is instantiated onto the form for them to ask. Start off with form set to something like 300 H x 500 w. Once I get more controls than will fit on the form, I increase the size of the form programmatically.

>Works good at first but after a few questions, form grows to be off the bottom of the screen. So then I thought I have to limit the size of the form to some max. But then my controls do not show.
