Scrollable gridview with updatepanel HELP

I solved the problem by adding check in your script :

Add l.id = "HeaderGrid"; And check the existence of page  

(function (a) {
    a.fn.Scrollable = function (b) {
        var c = {
            ScrollHeight: 300
            Width: 0
            IsInUpdatePanel: false
        } ;
        var b = a.extend (c, b);
        return this.each (function () {
            var c = a (this). get ( 0);
            var d = c.id;
            MakeScrollable (c, b);
            if (b.IsInUpdatePanel) {
                var e = Sys.WebForms.PageRequestManager.getInstance ();
                if (e! = null) {
                    e.add_endRequest (function (c, e) {
                       if($("div#HeaderGrid").length == 0){
                            MakeScrollable (a ("#" + d). Get ( 0 ), b)
                        }
                        
                    } )
                    
                }
            }
        } )
    }
}) (jQuery);

 Your jquery plugin not working with multiple update panels :)
