I have RadTabs and RadAjaxpanel with asp.panel inside. Depending on what tab is click im loading dynamicly control inside asp.panel. Controls are loading without postback that is ok... but no javascript functions are not found on new control... if i click view source, indeed i see source from old control and that is not strange that i cant reach it. Can somebody help me to avoid this problem ASAP b/s i cant link treeview with js functions on my second control.
