Can an ASP.NET TreeView expand upwards instead of downwards?

Question

Can an ASP.NET TreeView, when you click the + sign be made to expand upwards instead of downwards? So that "Children" nodes appear above their "Parents."

Essentially I want to logically be taking what would normally be a singular leaf node, making it the root of my tree, and making what is logically it's Parent into a Child Node on my Tree, but have that Child Node still display above the Parent when the Parent gets expanded.

Think a company OrgChart, but starting with the employee (leaf node) and going up.

I can't seem to find anything specifying direction on MSDN. I would like to avoid having to re-write how the Javascript of the TreeView works, but would be open to it if no other way is possible.

Answer 1

No, you cannot do that with the TreeView component.
Attempting to do that would involve inheriting from the TreeView and writing your custom Render function.

There is a simpler approach to it though. You could write out all your data to a json object, and use one of the numerous javascript data visualization libraries to present it.

I really like the javascript InfoVis toolkit. You can make very detailed graphs using it.
