Is it wrong to access TreeViewItems in WPF’s TreeView?

Question

I’ve been having issues with the TreeView in WPF. This control makes it very hard to access the TreeViewItems it’s showing.

On several occasion

Answer 1

No, I dont see in what way accessing the items of a treeview is wrong.

I think the difficulties you are encountering are because you aren't seeing the treeview as it should be.

A leaf has a parent, but no children. A node can have a parent, and can have children. A node without a parent is a root.

Based on these principles (SourceMaking Composite pattern) you should be able to do whatever you want using recursivity. (in both XAML and code)
