I have a challenging view that I'm trying to put together and hoped maybe someone has already done something similar or knew of a resource (blog post or something) that could help. My challenge is that I have a ConductorViewModem/View which uses a
ListBox control to show the Items. This is all setup and dandy. My ListBoxItem Templates are all set and working and I have a few different templates each matching to a different ChildViewModel/View.
Now however I have to add a new ChildViewModel that is itself a Conductor and will have a nested ListBox. Again not that big a deal except I want to size the nested listbox such that the entire parent listItem still displays on the screen. Basically
I don't want two sets of scroll bars that both go off the screen.
On paper I know what to but I'm having issues making it work. Basically I know that I need to element bind the max height of the child listbox to a % height of the parent listboxitem and then I have to limit the MaxHeight of the parentListBox item
to a % of the ViewPort of the Main ListBox.
I've googled for quite a while and found bit and pieces although much references SL2 & SL3.
As an example (assuming 60px for scrollbars and other conent) if the height of my parent list box is 600px I want the maxHeight of the listboxItem to be 540px which means the max height of the nestedChildListBox is 480px. I just need a way to implement that
logic dynamically and what elements I need to pull the information from.
I also need something that isn't going to mess up with Virtualizing etc. Is there a codebehind event I can tack into? I would love a mvvm solution.
Any thoughts? thx
