i have 2 listboxes in the radmultipage and have set RenderSelectedPageOnly= true on the radtabstrip with 3 tabs. The problem that i run into is that if i move items over to second listbox and click on the third or first tab, it won't save all my changes on the listbox. i tried to enable PersistClientChanges but still nothing in the second listbox get saved. however if i take out renderselectedpageonly, then it works fine. so is there away for me to say if next tab or previous is clicked on, render current page first before render the selected page? please help me. if that could be done in javascript that is great too but if you have both client and server side that would be great. thank you very much
