What I am trying to do is change the TreeView into a table tree view, an expandable tree that contains cells for other related data per each node. The problem is I have not found anyway to hack around the "internal Render" method of the TreeNode object (it's not a Control) or the protected internal RenderContents of the calling TreeView (of which I thought I could override, but I can't call node.Render()).
I also tried implementing (hacking) an adapter, but then this totally removes the content that I was trying to hack into the TreeNode.RenderPostText method. Make sense, but sucks in my case. Sigh...
So has anyone done this? If not, what's a good alternative to achieve a Tree Grid (Table) View type of control?
