I have a ListBox with horizontal scrolling, and each item consists of a two row grid. The first row contains an image, and the second row a border used to render a reflection of the first.
(Yeah, yeah. I know. Yet another coverflow attempt...)
I need some help with the sizing of the images. If I don't specify any size, it will render the image at full size, but I want it to be restricted by height of the grid row. If the window resizes, the images should resize.
Any clues?
Update:
I have now changed the code a little. First of all I have removed a unnecessary trigger, but the important part is
- Disabled vertical scrollbar on listbox.
- Removed height on coverImage
- Changed from layoutTransformation to RenderTransformation
- Shrink non-selected item instead of scaling selected item.
This gives me nearly what I want. There is a gap between the coverImage and the coverReflection that I cant find a reason for. Any clues for that, og maybe I should post a new question...?
Second Update:
I think I have a solution for the reflection-gap to now. It feels a little awkward, though. I guess there are better ways of doing it.
What I've done is - I'm no longer flipping the border, I'm flipping the visual brush instead. - I have added a TileMode="Tile" for the visual brush
Now, I'm not sure why this works, but it's coming close to what I want, so...
