With WPF GUI elements, it can happen that you like to connect two detached elements with each other. A classic example are comboboxes within tables. You want to read the value of the combobox with the corresponding row. For this the binding of elements is necessary. Enclosed a small example, how you can accomplish this:

I know you posted this a few years ago now, but just found it and it helped me solve a problem I had. I wanted to bind a combobox to a text input file, and reading your code and amending slightly, I got it working, so huge thanks from me.
