I have 8 tab panels with 1 iframe each, in ajax tab container, I need to clear the values of controls in each tab on switching to other tab, so that in the next visit, there shouldn't be any values previously given, for this I used onclient click event for each tab panel , where i reassigned same source to the iframe.src in that tab., it's working fine with tab 1, as moving formward , when I click on any other tab ,1st tab in shown....even if I clearly mentioned the same src for that particular iframe previously it had,here i am just re assigning the same page address.I tried document.forms[0].submit(); no use....
Please help me solve this issue or suggest any other alternative.
...Thanks
