Description
How can I use the Kendo UI TreeView as an editor in the Kendo UI Grid for jQuery?
Solution
The following example demonstrates how to use the TreeView for batch editing in the Grid.
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function () {
var crudServiceBaseUrl = "//demos.telerik.com/kendo-ui/service",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products",
dataType: "jsonp"
},
update: {
url: crudServiceBaseUrl + "/Products/Update",
dataType: "jsonp"
},
destroy: {
url: crudServiceBaseUrl + "/Products/Destroy",
dataType: "jsonp"
},
create: {
url: crudServiceBaseUrl + "/Products/Create",
dataType: "jsonp"
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } },
UnitPrice: { type: "number", validation: { required: true, min: 1 } },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true } }
},
}
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
edit: function (e) {
//checking if a cell from the Test column is opened for editing
var dummyInput = e.container.find("input[name='test']");
if (dummyInput.length > 0) {
var treeView = $(e.container).find(".treeViewEditor").data("kendoTreeView");
var originalItem = treeView.findByText(dummyInput.val());
if (originalItem != null) {
// Select the item based on the field value
treeView.select(originalItem);
}
}
},
navigatable: true,
pageable: true,
height: 550,
toolbar: ["create", "save", "cancel"],
columns: [
"ProductName",
{
field: "test", title: "Test", width: 120,
editor: function (container, options) {
var input = $("<input class='tveInput'/>");
input.attr("name", options.field);
var tvDiv = $("<div class='treeViewEditor'></div>");
$(tvDiv).kendoTreeView({
animation: false,
dataSource: [
{
text: "foo1"
},
{
text: "foo2",
items: [
{ text: "bar" },
{ text: "bar1" },
{ text: "bar2" }
]
}
]
});
var treeView = $(tvDiv).data("kendoTreeView");
$(tvDiv).find(".k-in").mousedown(function (e) {
var clickedNode = $(e.toElement).closest("[role=treeitem]");
var dataItem = treeView.dataItem(clickedNode);
var dummyInput = clickedNode.closest("[role=gridcell]").find("input[name='test']");
dummyInput.val(dataItem.text);
dummyInput.trigger("change");
});
tvDiv.appendTo(container);
input.appendTo(container);
}
},
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: 120 },
{ field: "UnitsInStock", title: "Units In Stock", width: 120 },
{ field: "Discontinued", width: 120 },
{ command: "destroy", title: " ", width: 150 }],
editable: true
});
});

display: none;
