This is my code for updating a dynamic 'thumbnail' scroll group. In CreateThumbnailGroup(), you'll see that I prepass the folder items to get the maximum width for the ScrollGroup GROUP_THUMBNAIL_SCROLL. Of course, this endeavor doubles the time it takes to load all of the bitmaps (as they are loaded twice - once for calculation, once to set the BitmapButton). Is there any way that the group's width could be set after the fact to avoid the prepass? Or would you suggest just getting the count of elements that 'might' have a bitmap and preallocating an array of BaseBitmap which is then disposed of upon exiting CreateThumbnailGroup()?
