Use TreeView as Custom Editor
The following example demonstrates how to use the TreeView for batch editing in the Grid.
Example
<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);
}
}
},

toolbar: ["create", "save", "cancel"],
columns: [

editor: function (container, options) {
var input = $("<input class='tveInput'/>");
input.attr("name", options.field);
var tvDiv = $("<div class='treeViewEditor'></div>");
$(tvDiv).kendoTreeView({

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 },
