Persist the State of the Grid Automatically

Environment

Product Progress Kendo UI Grid

Description

How can I automatically persist the sort, filter, and group Grid options when the user leaves the page and keep the look of the Grid the same as the user closed the tab?

Solution

The state of the Grid is persisted in the beforeunload event handler. This way, any operation which the user performs before leaving the page is persisted. To restore the Grid state, use the document.ready event.

The autoBind property of the Grid is able to detect any options that are already persisted, which prevents the multiple requests of data.

<div id="grid"></div>

<script>
$(document).ready(function () {

    var options = localStorage["grid-options"];

    $("#grid").kendoGrid({
    // prevent requesting data multiple times if there are persisted options
        autoBind: !options,
        dataSource: {
            type: "odata",
            transport: {
            read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
            },
            pageSize: 20
        },
        height: 550,
        groupable: true,
        sortable: true,
        reorderable: true,
        resizable: true,
        columnMenu: true,
        filterable: {
            mode: "row"
        },
        pageable: {
            refresh: true,
            pageSizes: true,
            buttonCount: 5
        },
        columns: [{
            field: "ContactName",
            title: "Contact Name",
            width: 250,
            locked: true
        }, {
            field: "ContactTitle",
            title: "Contact Title",
            width: 350
        }, {
            field: "CompanyName",
            title: "Company Name",
            width: 350
        }, {
            field: "Country",
            width: 450
        }]
    });

    var grid = $("#grid").data("kendoGrid");

    if (options) {
        grid.setOptions(JSON.parse(options));
    }

    window.onbeforeunload = function() {
        localStorage["grid-options"] = kendo.stringify(grid.getOptions());

        return;
    }
});
</script>
