Hi,

I have a Solidworks Addin in which I call ICommandManager.AddCommandTab to add my own command tab.  When an end-user selects my command tab, I would  like to put up a PropertyManagerPage.  Furthermore, when the end-user selects other command tab (i.e. exits out of my command tab), I would like to close the ProperyManagerPage and do other cleanups.  I think the proper place to do this is in the event call-back method for switching command tab (entering from other tab to my tab; and exiting my tab to other tab).  Is there such an event?

Thanks.
