状态持久性

Grid使您可以保存用户的自定义设置，并在用户将来再次登录后将其还原。

要保留以前应用于其结构的设置，请使用Grid的getOptions和setOptions方法。这些方法允许您在需要时序列化Grid的当前状态，并在以后恢复该状态。

<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" href="styles/kendo.common.min.css" />
<link rel="stylesheet" href="styles/kendo.default.min.css" />
<link rel="stylesheet" href="styles/kendo.default.mobile.min.css" />

<script src="js/jquery.min.js"></script>


<script src="js/kendo.all.min.js"></script>

</head>
<body>

<div id="example">
<div class="box wide">
<a href="#" class="k-button" id="save">Save State</a>
<a href="#" class="k-button" id="load">Load State</a>
</div>
<div id="grid"></div>

<script>
$(document).ready(function () {
$("#grid").kendoGrid({
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");

$("#save").click(function (e) {
e.preventDefault();
localStorage["kendo-grid-options"] = kendo.stringify(grid.getOptions());
});

$("#load").click(function (e) {
e.preventDefault();
var options = localStorage["kendo-grid-options"];
if (options) {
grid.setOptions(JSON.parse(options));
}
});
});
</script>
</div>

</body>
</html>

层次结构

Grid通过以分层方式显示其表数据，提供用于可视化父记录和子记录之间关系的选项。

要在Grid中实现层次结构，请连接其detailInit事件并根据父键字段值过滤子表中的记录。

<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" href="styles/kendo.common.min.css" />
<link rel="stylesheet" href="styles/kendo.default.min.css" />
<link rel="stylesheet" href="styles/kendo.default.mobile.min.css" />

<script src="js/jquery.min.js"></script>


<script src="js/kendo.all.min.js"></script>

</head>
<body>

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

<script>
$(document).ready(function() {
var element = $("#grid").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Employees"
},
pageSize: 6,
serverPaging: true,
serverSorting: true
},
height: 600,
sortable: true,
pageable: true,
detailInit: detailInit,
dataBound: function() {
this.expandRow(this.tbody.find("tr.k-master-row").first());
},
columns: [
{
field: "FirstName",
title: "First Name",
width: "110px"
},
{
field: "LastName",
title: "Last Name",
width: "110px"
},
{
field: "Country",
width: "110px"
},
{
field: "City",
width: "110px"
},
{
field: "Title"
}
]
});
});

function detailInit(e) {
$("<div/>").appendTo(e.detailCell).kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
serverPaging: true,

serverFiltering: true,
pageSize: 10,

},
scrollable: false,

columns: [
{ field: "OrderID", width: "110px" },
{ field: "ShipCountry", title:"Ship Country", width: "110px" },

{ field: "ShipName", title: "Ship Name", width: "300px" }
]
});
