That won't work. you can't call server-side methods from javascript. you could revoke a postback by setting your OnClick to __doPostBack().

  • the page rendered give me [input name="ctl00$CPH1$btnBrowse" type="button" id="btnBrowse" value="..." class="lookupBtn" onclick="file1.click()"], [input name="ctl00$CPH1$file1" type="file" id="file1" onchange="test()"],[input onclick="__doPostBack('ctl00$CPH1$hdnBtn','')" name="ctl00$CPH1$hdnBtn" type="button" id="hdnBtn"] – user1237362 Feb 28 '12 at 09:20
  • and when i debug with developers tool in IE, it does goes into the __doPostBack function, but it still doesn't trigger the back end function that i need – user1237362 Feb 28 '12 at 09:22
