Is there any possibility to influence the inital states of dnnPanels and dnnTabs from code behind (server side). Eg., I click on a button in the first panel/tab, dependig on some input fieds there the content in the second tab is filled and the second panel (or tab) is visible and displays a list of something, and then I click on any row in the list, panel/tab 3 opens with some details. (Ideally panel/tab 3 is invisible unless a record on tab 2 is clicked/selected).

Or are there some server-side controls to realize this?

Best wishes
Michael
