I have a RadMultiPage with several pageviews, each of which is tied to a specific tab in a RadTabStrip. When the page loads I programmatically determine which tabs are accessible, and hide the rest. I then iterate over the pageviews in the associated RadMultiPage to mark them visible if the tab is also visible. Once that's done I check if there are any visible tabs, and if there are I set the selectedindex of both the tabstrip and the multipage to 0.
The tabs are showing/hiding correctly, but the multipage pageviews are not. If the first tab/pageview is not visible the tab is gone, but the pageview still shows. If I set all of the pageviews to visible=false but leave the tabs visible I can click through all the tabs and their pageviews load which is not what I expect.
If a control is set to "Visible=false" I would expect it to be completely removed from the server side and have no possibility to render. Why is this not happening? Here's some of the relevant code:
