 var GetGridState = function(dataSource, grid$) {
        var state = {
            page: dataSource.page(),
            pageSize: dataSource.pageSize(),
            sort: dataSource.sort(),
            group: dataSource.group(),
            filter: dataSource.filter(),
            scroll: $(".k-grid-content", grid$).scrollTop(),
            aggregate: dataSource.aggregate()
        };
 
        if (state.pageSize === undefined) {
            delete state.page;
            delete state.pageSize;
        }
 
        return state;
    }
    
    Is there a better way to just not create the pagePagesize properties orignally without checking later?
