Access text selection within a TreeNode (WinForms)

Question

Is it possible to access information about the text selection within an editable TreeNode of a WinForms TreeView?

I discovered methods such as BeginEdit() and EndEdit(bool cancel), but I need finer granularity of control -- something like TextBoxBase.SelectionStart and SelectionLength properties, but on the node itself.

Is this possible in C#/.Net?

You will need to do some native interop work to get the edit control that is used for the label. To get this control, you need to use the TVM_GETEDITCONTROL message, sending it to the tree view instance in which you want this behavior.

Once you have the window handle from this message, you can then use the EM_SETSEL message on the handle to set the selection.
