In WinForms TreeViewAdv , you could achieve this feature by getting hold of the ToolTipControl and HelpTextControl associated with the TreeViewAdv, and handling their BeforePopup events as shown below:

this.treeViewAdv1.ToolTipControl.BeforePopup +=
    new CancelEventHandler(TooltipBeforePopup_EventHandler);

this.treeViewAdv1.HelpTextControl.BeforePopup += 
    new CancelEventHandler(TooltipBeforePopup_EventHandler);

private void TooltipBeforePopup_EventHandler(object sender, CancelEventArgs e)
{
    // Introduce any desired delay here
    Thread.Sleep(delay);
}

Me.treeViewAdv1.ToolTipControl.BeforePopup +=
    New CancelEventHandler(TooltipBeforePopup_EventHandler)

Me.treeViewAdv1.HelpTextControl.BeforePopup += 
    New CancelEventHandler(TooltipBeforePopup_EventHandler)

Private Sub TooltipBeforePopup_EventHandler(ByVal sender As Object, ByVal e As CancelEventArgs)
    ' Introduce any desired delay here
    Thread.Sleep(delay)
End Sub
