kendo grid shared data source - kendo-ui

Question

This is my main grid. In action i go to the database and get all data. I want to put an another grid that will use same data type. And this grid will use same data source with filter that i specified. I don't want to go database again.
For example
Grid1: show all data
Grid2: show OrderAmount>100
(Html.Kendo().Grid<CustomerOrder>()
.Name("Orders")
.Events(events => events.DataBound("onDataBound"))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Read(read => read.Action("OrderListAjax", controller))
.PageSize(Constants.PageSize)
.Columns(columns =>
{
columns.Bound(p => p.CustomerNumber).Title("CustomerNumber");
columns.Bound(p => p.CustomerName).Title("CustomerName");
columns.Bound(p => p.OrderAmount).Title("OrderAmount");
})
)

Answer 1

I tried a different way in below and it works also.
// Take the data source from main grid
var mainSource = $("#Orders").data("kendoGrid").dataSource.data().toJSON();
// Prepare your query on main grid source
var orderAmountQuery = kendo.data.Query.process(mainSource, {
filter: {
logic: "and",
filters: [
{
field: "OrderAmount",
value: parseInt("100"),
operator: "gt" // greater than
}
]
}
});
// Create a new datasource for set filtered datasource
var orderAmountQueryDataSource = new kendo.data.DataSource({
pageSize: 15,
});
orderAmountQueryDataSource.data(orderAmountQuery.data);
// set grid2's data source with filtered dataSource
var grid2 = $("#Grid2").data("kendoGrid");
grid2.setDataSource(orderAmountQueryDataSource);

Your main answer is here :
is it possible to copy a grid datasource to a new datasource, a new datasource that loads all data?
But for your case which you need to do filtering as well you can use this:
Add your second grid in CSHTML:
<div id="MySecondGrid"></div>
Use the following Javascript:
// Get the first datasource
var ds1 = $("#Orders").data("kendoGrid").dataSource;
// Filter the second datasource
var ds2 = $.grep(ds1._data, function (item) { return item.OrderAmount > 100; });
ds2.serverPaging = false;
// Set the second datasource
$("#MySecondGrid").kendoGrid({
dataSource: ds2
});
