Displaying Connecting Lines in TreeView (SL & WPF)

The ability to show connecting lines between parent-child node is pretty useful and definitely gives a better representation in case of large data. TreeView controls over some platforms have ShowLines property which user can set to see the connecting lines automatically. SL/WPF C1TreeView controls don't expose these properties in a straight way as you have a lot more control over the entire look and feel of the control and that's the power of xaml :) Now, to achieve a similar connecting lines with C1TreeView, you have to edit the default template and add required elements (rectangles) in the template.
