I can hide a Sliding Panel but not its Tab in AHviewPager

You can only remove a page completely with AHPageContainer.DeletePage() and then you have to update the tabs with AHViewPagerTabs.NotifyDataChange. If you don't notify the tabs about the new page structure then it may crash.

If you keep a reference to your pnlX you can add this page later again with AHPageContainer.AddPageAt() at the old position.

Markus:
I am afraid that is what I thought what your response would be. There is always a risk in deleting and then recreating pages. In my case I may have 7 pages and 2 or 3 of them may not be needed temporarily as the data in them is not required, which will change the postion of the rest. Then the deleted ones may have to be reinstated almost immediately after that. I thought a HIDE option will make it a little safer to bounce back and forth.
I will weigh my options whether using tabhost where I can hide pages or sliding panels where I cannot.
Thank you very much
