$('#draggable').draggable();
return false;
}
});
return false;
});
");
?>
View Button is working fine and open a CJuiModel on click but when I add a new Location in CGridView .
On Clicking on view button my CJuiModel is not opening and page is redirecting to Url.Why my jquery is getting failed on updating CGridView. Help..

Answer 1

Change ajax call using JQuery 'on' instead direct event binding:
This:
...
$('.exb-location').click(function(){
...
Change for:
...
$('.exb-location').on('click', '.exb-location', function(){
...
Html Elements are destroyed and regenerated after CGridview refresh. Direct JQuery events only work with existing elements before DOM load. When they are removed, or new elements are added later, direct events don't work.
