Resize Outlook Form Region

Question

When I found out that I couldn't control the expanding/collapsing of the form regions, it made me sad. I decided to look into controlling how much the form pops out. This has made me sadder still. It seems that while I can control the height, the user won't be able to set the height higher than what I set it to. I couldn't find a height property that controls just how far the region is set without changing the actual height of the form. I'm guessing it's somewhere in the this.OutlookFormRegion, but I haven't had any luck. Any direction towards solving this would be very much appreciated. Thanks.

Answer 1

Did you try to use the Form property of the FormRegion class to set up the required properties?

There are a lot of limitations exist with form regions. The Creating Outlook Form Regions section in MSDN describes form regions in depth.

I'd suggest using Advanced Outlook Form Regions instead. They allow to manage the form in the way you need - hide/show, collapse, change the size and layout at runtime and etc.

Another approach is to subclass an Outlook window and inject your own custom form. See Adjacent Windows In Outlook and Creating Adjacent Windows In Outlook sample project.

Answer 2

If your FormRegionType is Adjoining, after changing to your form region's e.g. Height property, call this.OutlookFormRegion.Reflow() to request that Outlook redo form layout. At least that works well for me in Outlook 2013.
