Kendo Grid select over multiple pages - kendo-grid

Question

I have created a kendo grid using Asp.Net MVC wrappers. I have included a checkbox for selecting multiple rows made the wiring and everything works ok. However, I have issues, when I change page, or do a filtering as the selecting rows/checkbox disappear.
What is the solution for this problem?

You need to use .PersistSelection(true) to ensure rows remain selected when changing pages:
#(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.OrderViewModel>()
.Name("rowSelection")
.Columns(columns => {
columns.Bound(o => o.ShipCountry).Width(300);
columns.Bound(p => p.Freight).Width(300);
columns.Bound(p => p.OrderDate).Format("{0:dd/MM/yyyy}");
})
.Pageable(pageable => pageable.ButtonCount(5))
.Selectable(selectable => selectable
.Mode(GridSelectionMode.Multiple))
.PersistSelection(true)
.Navigatable()
.DataSource(dataSource => dataSource
.Ajax()
.Model(m=>m.Id("OrderID"))
.PageSize(6)
.Read(read => read.Action("Orders_Read", "Grid"))
)
Also ensure you have an id column declared in the DataSource, like .Model(m=>m.Id("OrderID")) in the example, otherwise it will fail.

I had issues with the jQuery grid.select() however:
var grid = $('#rowSelection').data('kendoGrid');
var rows = grid.select();
This only seemed to return rows selected on the currently displayed page rather than all the rows selected across all the pages.
