这实际上取决于您要显示的数据，以及它的数量，但是最简单的最清晰的方式可能就像 TreeView [ ^ ] - 设计为分层显示工具，没有别的。

检查这些：

带有ComboBox下拉节点的TreeView控件 [ ^ ]

代表分层数据.net winforms [ ^ ]

工作使用分层数据显示 [ ^ ]

I want to show Data Hierarchy and as user click to specific hirarchy item details description should be display in text boxes or girdview. Which Control will be best and how to use it?? in Windwos Forms m using VS 2012 SQL 2012

It really depends on what data ayou are trying to display, and how much there is of it, but the simplest and clearest way is probably something like a TreeView[^] - which is designed as a hierarchical display tool and nothing else.

Check these:
A TreeView Control with ComboBox Dropdown Nodes[^]
Representing hierarchical data .net winforms[^]
