Need to know when a CustomTaskPane is closed in office 2010

Question

A CustomTaskPane has two events in Office 2010, and one of them, VisibleChanged, is fired when someone x-es out the CustomTaskPane. BUT, in Office 2010 you will also get a callback to the VisibleChanged event when you click the File menu AND when you close the file menu! In other words I have no clue if someone is actually x-ing out the CustomTaskPane or hitting the File menu. I only find recommendations of using the VisibleChanged event, but this is not good enough.

Anyone have a workaround for this?

Thanks in advance,
Martin

Hi Martin,

Thank you for posting.

You can trap whether the File tab is clicked via custom ribbon and call the backstage's onShow mentod. In this way, you can know that whether someone have closed the CustomTaskPane or just hit the File Menu.

Best Regards,

I resolved this by adding <backstage onShow".."> in my xml. For others who have an ordinary ribbon add-in and needs to find out if someone X-ed out the pane, read here (very easy fix): http://social.msdn.microsoft.com/Forums/en-US/officegeneral/thread/208ce6e1-1fc7-47ca-8f77-699892a6e61c
