Hi I have a doubt in client side autorefresh concept. In my code i have one checkbox dropdownlist and grid.If I click the checkbox the grid should be refresh the particular seconds based on the dropdown index select. I tried the following ways Using Jquery $(#Cb_Ajax).on('click' function () { var $cb = $(this); if ($cb.is(':checked')) { var $container = $(#content); // var $cin=$('# ').val('Date.now.toString()'); var strUser = $(#cc_autorefresh option:selected).text() * 1000; $container.load(document.URL + ' #content'); // alert(strUser); var refreshId = setInterval(function () { var param = new Date(); var param2 = param1.getDate() + '/' + (param1.getMonth() + 1) + '/' + param1.getFullYear() + ' ' + param1.getHours() + ':' + param1.getMinutes() + ':' + param1.getSeconds(); $container.load($('#content').text(param2) strUser); // $container.load(#content strUser); alert(strUser); }) } else { clearTimeout(reloading); } }); }); Using Javascript function checking() { var chkEnabled = $get('Cb_Ajax'); var timer = $find('Timer1'); var Label = $get('Label22'); var e = document.getElementById(cc_autorefresh); if (e.selectedIndex > 0) { var strUser = e.options[e.selectedIndex].text * 1000; // alert(strUser); //alert(timer); timer.set_enabled(chkEnabled.checked && e.selectedIndex > 0 == true); timer.set_interval(strUser); if (timer.get_enabled()) { timer._startTimer(); binddata() } else { timer._stopTimer(); } } else alert(Select the time Interval); } BUT both are not working .Please suggest me what can i do furthur Thanks in advance
