Disabling Tooltips in a TreeView Control
It is possible to disable tooltips that are shown when hovering a node by adding the TVS_NOTOOLTIPS
window style to the control’s creation parameters:
Imports System.Windows.Forms
Public Class TooltipLessTreeView
Inherits TreeView
Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Const TVS_NOTOOLTIPS As Int32 = &H80
Dim cp As CreateParams = MyBase.CreateParams
cp.Style = cp.Style Or TVS_NOTOOLTIPS
Return cp
End Get
End Property
End Class
