ToolStripItem.ToolTipText property not working in Windows 8

[winman]

Hi,

We have a application developed using .NET. We use some ToolStripMenuItem in project and used ToolStripItem.ToolTipText property to display description of items.It is working fine in Windows XP. But now we are using some Windows 7 and Windows 8 PCs and ToolStripItem.ToolTipText property was not working.
After sometime find out that tooltip property is working if we use .net framework 2.0 and not working if we use .net framework 4.0 in Windows 8.
This was the initial config file lines

<startup>
	<supportedRuntime version="v4.0"/>
    <supportedRuntime version="v2.0.50727"/>
  </startup>

tooltip working if we interchange supportedRuntime lines. Why this is happening?windows 8 doesn't support .net framework 4.0? Or ToolStripItem.ToolTipText doesnot work on .net framework 4.0?
Thank you

Is the ShowItemsToolTips property of the MenuStrip set to True?

Is the ShowItemsToolTips property of the MenuStrip set to True?

Actually no.We will do that. But what i didn't understand is why its not working in Windows 8 only? Windows XP doesn't need ShowItemsToolTips set to be true?

I don't know why exactly you're having this experience but yes, WinXP also needs this property to be set to True. I'm unsure but maybe (I actually doubt that this is true) the property was set to true by default on .Net 2.0 while (for MenuStrips but not for ToolStrips) it's set to false by default in later versions. In either case this property has to be set to True for tooltips to be shown regardless of what Windows version you're using.
