This seems to be a .Net Framework bug. Does anyone know if a fix is in the
pipeline or of a workaround?
The problem arises if a WinForms TreeView is placed on top of a form which
in turn is on another form. In this situation the tooltips that normally
appear when a treenode is too long to be displayed in the treeview are not
shown properly; they are clipped by the main form.
e.g. Arrangement is like this...
MainForm
ChildForm [TopLevel = false, DockStyle.Right]
TreeView [DockStyle.Fill]
My theory, based on some Spy++ investigation, is that two Win32 tooltip
windows are created, one for the mainform and one for the childform, but in
this situation the treeview prefers the tooltip window of the childform,
which is before the mainform in the windows z-order. So the tooltip gets
clipped by the MainForm.
