I have a page (ASP.net) that contains two update panels, in the first one I add some controls in the run time (Textbox) and I want to get the values of these dynamically add controls in the second update panel upon the certain action in this panel.
If any one could advice with a proper solution for this situation taking in consideration that the two panels can''t be merged in one update panel due to some business logic.
Thanks in advance :)
