I have a bunch of usercontrols, each with listboxes in them. I want to make it so that connections between items in these listboxes can be connected between the different controls, and show this visually by drawing lines between them (like in a diagram). That is, item1 in listbox1 is connected to item5 in listbox2 by drawing a line between them. My custom controls are placed in my own layout control.
What is the best way to achieve this in WPF?
