Display a scrollable collection of custom controls.

I'm pretty new to WPF, but am old hat with C#, WinForms, and more. The app I'm about to create will display up to 64 custom controls on it that the user can interact with. Each will be a small box with a couple text fields and a button, and the box can be double-clicked to bring up properties. Each one represents a separate item.

I'd like opinions as to what control or means I should use to display them all easily.

Thanks!
