获取剑道网格中所选项目的页面

Question

I have a kendo grid where I preselect one item that can be on any page. In many cases, my default selected item is not on page one (which is usually the first page you see), so the selected item is hidden. I need to get the page number of the data item. How can I do this? Is there a function that I've not seen yet from kendo?

As far as I remember, you can do something like that:

var index = dataSource.indexOf(item) + 1; // find where item is in data source

var pageSize = dataSource.pageSize(); // find how many items per page

var currentPage = Math.ceil(index/pageSize); // find at which page item is

dataSource.query({ page: currentPage, pageSize: dataSource.pageSize() }); // go to that page

.pageSize() , .query()
