Kendo DataSource create method not getting called - kendo-ui

Why is my transport's create method not being called when I click the "Save Changes" button on the grid? Everything appears to be working except my controller code for create isn't getting called.
Kendo Code:
var ds = new kendo.data.DataSource({
transport: {
read: {
cached: false,
url: '#Url.Action("GetListOfFacilities", "Tactic")',
dataType: "json"
}
}
});
var OrgdataSource = new kendo.data.DataSource({
transport: {
read: {
url: '#Url.Action("ReadOrganizations", "Tactic")',
dataType: "json"
},
create: {
url: '#Url.Action("AddOrganization", "Tactic")',
type: "POST",
dataType: "json"
}
},
batch: false
schema: {
model: {
id: "id",
fields: {
id: { type: "string", editable: false },
Name: { type: "string" }
}
}
}
});
$("#FacilityGrid").kendoGrid({
dataSource: OrgdataSource,
autoBind: true,
autoSync: true,
editable: { mode: "inline" },
selectable: true,
toolbar: ["save", "create"],
columns: [
{ command: ["destroy"], title: " ", width: "150px" },
{ field: "Name", title: "Facility Name", editor: OrgDropDownEditor },
]
});
function OrgDropDownEditor (container, options) {
$('<input required data-text-field="Text" data-value-field="Value" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
autoBind: true,
dataSource: ds
});
}
Controller Code:
[HttpPost]
public JsonResult AddOrganization(SelectListItem selectedOrg)
{
...
}
[HttpGet]
public string GetListOfFacilities()
{
var lst = new List<SelectListItem>();
lst.Add(new SelectListItem() { Value = "1", Text = "Facility 1" });
lst.Add(new SelectListItem() { Value = "2", Text = "Facility 2" });
lst.Add(new SelectListItem() { Value = "3", Text = "Facility 3" });
lst.Add(new SelectListItem() { Value = "4", Text = "Facility 4" });
lst.Add(new SelectListItem() { Value = "5", Text = "Facility 5" });
var json = new JavaScriptSerializer().Serialize(lst);
return json;
}

Try removing "id" from the fields object. It doesn't need to be in there if you have specified it as the id of the model.

I had the same problem like this. I have resolved it by defining a default value for my model fields. In your model you should provide a default value for Name field to prevent passing null to datasource.
schema: {
model: {
id: "id",
fields: {
id: { type: "string", editable: false },
Name: { type: "string" }
}
}
}

How to get field value when edit data in Kendo Ui treelist

I'm new in Kendo UI,and i have a question. Now i'm use TreeList / Editing and how to auto load value to other field when i edit value to first field ?
example:
1.serial number: 123456789
2.name : test
when i edit serial number 123456789 to first field and auto load name to second field.
To set the value of column B based on change made to a column A, you need to edit the model bound to the tree list. For this do the following:-
Handle edit event of the tree list. On this save the model to a
local variable.
Add an editor
template
to column A. On the select event set the value of model.
Below is a working code snippet:-
<div id="treelist"></div>
<script>
$(document).ready(function () {
var crudServiceBaseUrl = "https://demos.telerik.com/kendo-ui/service";
var model= null;
var employeesData=[{"EmployeeId":101,"FirstName":"Daryl","LastName":"Sweeney"},
{"EmployeeId":202,"FirstName":"Guy","LastName":"Wooten"},
{"EmployeeId":303,"FirstName":"Priscilla","LastName":"Frank"},
{"EmployeeId":404,"FirstName":"Ursula","LastName":"Holmes"},
{"EmployeeId":505,"FirstName":"Anika","LastName":"Vega"}];
var dataSource = new kendo.data.TreeListDataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/EmployeeDirectory/All",
dataType: "jsonp"
},
update: {
url: crudServiceBaseUrl + "/EmployeeDirectory/Update",
dataType: "jsonp"
},
destroy: {
url: crudServiceBaseUrl + "/EmployeeDirectory/Destroy",
dataType: "jsonp"
},
create: {
url: crudServiceBaseUrl + "/EmployeeDirectory/Create",
dataType: "jsonp"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
batch: true,
schema: {
model: {
id: "EmployeeId",
parentId: "ReportsTo",
fields: {
EmployeeId: { type: "number", nullable: false },
ReportsTo: { nullable: true, type: "number" },
FirstName: { validation: { required: true } },
HireDate: { type: "date" },
Phone: { type: "string" },
HireDate: { type: "date" },
BirthDate: { type: "date" },
Extension: { type: "number", validation: { min: 0} },
Position: { type: "string" }
},
expanded: true
}
}
});
$("#treelist").kendoTreeList({
dataSource: dataSource,
toolbar: [ "create", "save", "cancel" ],
editable: "incell",
height: 540,
dataBound: function (e) {
var items = e.sender.items();
for (var i = 0; i < items.length; i++) {
var dataItem = e.sender.dataItem(items[i]);
var row = $(items[i]);
if (dataItem.isNew()) {
row.find("[data-command='createchild']").hide();
}
else {
row.find("[data-command='createchild']").show();
}
}
},
edit: function(e) {
model = e.model;
},
columns: [{
field: "EmployeeId",
expandable: true,
title: "Serial Number",
width: 180,
editor: function(container, options) {
// create an input element
var input = $("<input/>");
// set its name to the field to which the column is bound ('lastName' in this case)
input.attr("name", options.field);
// append it to the container
input.appendTo(container);
// initialize a Kendo UI AutoComplete
input.kendoAutoComplete({
dataTextField: "EmployeeId",
dataSource: employeesData,
select: function(e) {
if(model !=null){
model.FirstName = e.dataItem.FirstName;
model.LastName = e.dataItem.LastName;
}
}
});
}
},
{ field: "FirstName", title: "First Name", width: 100 },
{ field: "LastName", title: "Last Name", width: 100 },
{ field: "Position", width: 100 },
{ field: "Phone", title: "Phone", width: 100 },
{ field: "Extension", title: "Ext", format: "{0:#}", width: 100 },
{ command: [{name: "createchild", text: "Add child"},"destroy" ], width: 240 }]
});
});
</script>
You can trigger your function when the row is being saved or when the edit field is being changed. Take a look at the list of events here and choose when exactly you want to make the changes. https://demos.telerik.com/kendo-ui/treelist/events
here is a example how to all a function when saving the changes: https://docs.telerik.com/kendo-ui/api/javascript/ui/treelist/methods/saverow
I´m not sure witch edit method you are using (inline, inCell or Popup edit mode) each method can use events like saveRow, beforeEdit...
Check all the events documentation here: https://docs.telerik.com/kendo-ui/api/javascript/ui/treelist#events

KendoGrid with KendoDropDownList

I'm trying to use kendoDropDownList in a column of my kendo grid and it's not working.
I'm following the examples on this post, but I guess I'm missing something.
KendoGrid DataSource:
var comboDataSource = new kendo.data.DataSource({
transport: {
read: {
type: "GET",
crossDomain: true,
url: url,
dataType: "json"
}
},
schema: {
data: "data",
model: {
id: "id",
fields: {
id: { editable: false, nullable: true },
typeId: { field: "typeId", defaultValue: 1 },
value: { type: "number", validation: { required: true } }
}
}
}
});
KendoDropDownList DataSource:
var typesComboDataSource = new kendo.data.DataSource({
transport: {
read: {
type: "GET",
crossDomain: true,
url: url,
dataType: "json"
}
},
schema: {
data: "data",
model: {
id: "typeId",
fields: {
typeId: { editable: false, nullable: true },
description: { validation: { required: true } }
}
}
}
});
KendoGrid:
$("#grid").kendoGrid({
editable: true,
toolbar: ["create", "save", "cancel"],
dataSource: comboDataSource,
columns: [{
title: "Type",
field: "typeId",
editor: typeDropDownEditor,
template: "#=getType(typeId)#"
}, {
title: "Value",
field: "value"
}]
})
function typeDropDownEditor(container, options) {
$('<input data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
dataTextField: "description",
dataValueField: "typeId",
dataSource: typesComboDataSource,
change: function (e) {
var dataItem = e.sender.dataItem();
options.model.set("typeId", dataItem.typeId);
}
});
}
function getType(typeId) {
var data = typesComboDataSource.data();
for (var idx = 0, length = data.length; idx < length; idx++) {
if (data[idx].typeId === typeId) {
return data[idx].description;
}
}
}
For some reason I'm getting the error ReferenceError: getType is not defined and I don't know why.
And if I put the function directly on the template, my data is loaded, but the type field displays as undefined. My typesComboDataSource was not trigger.
$("#grid").kendoGrid({
editable: true,
toolbar: ["create", "save", "cancel"],
dataSource: comboDataSource,
columns: [{
title: "Type",
field: "typeId",
editor: typeDropDownEditor,
template: function getType(typeId) {
var data = typesComboDataSource.data();
for (var idx = 0, length = data.length; idx < length; idx++) {
if (data[idx].typeId === typeId) {
return data[idx].description;
}
}
}
}, {
title: "Value",
field: "value"
}]
});
Can someone help me, please?
Thanks!
Your template functions are evaluated at runtime outside the JQuery code block scope, so it doesn't know what getType is when the code actually runs. Move both the typeDropDownEditor() and getType() functions outside your JQuery block and you should be good to go.
Here's a JSBin example displaying what you're trying to accomplish:

Kendo UI grid (inline edit) update and cancel not working

i create grid with data by javascript. when i click edit button at first time on any row and click update button. values in first row are null and then i edit other row i can't update or cancel, both button are not working.
when i refresh then click edit and then click cancel that row has removed i don't know why?
What's happend? How to fix?
Data
var detail = new Array();
for (var i = 1; i < 6; i++) {
detail.push({
Score: i,
Condition: 0,
ValueStart: 0,
ValueEnd: 0,
});
}
Grid
for (var i = 0; i < 3; i++) {
$("#GridScoreRangeContent").append("<div id='scoreRangeGrid_"+i+"'></div>");
$("#scoreRangeGrid_"+i).kendoGrid({
dataSource: {
data: detail,
batch: true,
schema: {
model: {
fields: {
Score: { editable: false },
Condition: { defaultValue: { Value: 1, Text: "Less than" }, validation: { required: true } },
ValueStart: { type: "number", validation: { required: true, min: 1 } },
ValueEnd: { type: "number", validation: { required: true, min: 1 } },
}
}
}
},
columns: [{ field: "Score", title: "Score" }},
{ field: "Condition", title: "Condition", editor: ScoreRangeDropDownList, template: "#=Condition#" },
{ field: "ValueStart", title: "Start" },
{ field: "ValueEnd", title: "End" },
{ command: ["edit", "destroy"], title: " ", width: "180px" }
],
editable: "inline"
});
}
Load Dropdownlist
function ScoreRangeDropDownList(container, options) {
$.ajax({
url: GetUrl("Admin/Appr/LoadDropdownlist"),
type: 'post',
dataType: 'json',
contentType: 'application/json',
traditional: true,
cache: false,
success: function (data) {
$('<input required data-text-field="Text" data-value-field="Value" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
autoBind: false,
dataSource: data,
dataTextField: "Text",
dataValueField: "Value",
});
}
});
}
Kendo seems to rely on a model ID when saving/updating. So in your dataSource, you have to specify an id:
model: {
id: "Id",
fields: {
Id: { type: "number" },
Score: { editable: false },
Condition: { defaultValue: { Value: 1, Text: "Less than" }, validation: { required: true } },
ValueStart: { type: "number", validation: { required: true, min: 1 } },
ValueEnd: { type: "number", validation: { required: true, min: 1 } },
}
}
What dmathisen is suggesting is definitely important but in addition it is important that the <input/> you create has a name attribute equal to the name of the column. You can use the value of options.field again as in the code from the Kendo Demos page example:
// create an input element
var input = $("<input/>");
// set its 'name' to the field to which the column is bound
input.attr("name", options.field);
// append it to the container
input.appendTo(container);
// initialize a Kendo UI Widget
input.kendoDropDownList({
.
.

Set the selected text or value for a KendoDropDownList

I'm using Durandal and Kendo UI. My current problem is the edit popup event on my grid. I cannot seem to set the selected value on my dropdown.
I can debug and inspect, and I indeed do see the correct value of e.model.InstrumentName nicely populated.
How can I set the value/text of those dropdowns in edit mode ?
Here's my grid init:
positGrid = $("#positGrid").kendoGrid({
dataSource: datasource,
columnMenu: false,
{
field: "portfolioName", title: "Portfolio Name",
editor: portfolioDropDownEditor, template: "#=portfolioName#"
},
{
field: "InstrumentName",
width: "220px",
editor: instrumentsDropDownEditor, template: "#=InstrumentName#",
},
edit: function (e) {
var instrDropDown = $('#InstrumentName').data("kendoDropDownList");
var portfDropDown = $('#portfolioName').data("kendoDropDownList");
instrDropDown.list.width(350); // let's widen the INSTRUMENT dropdown list
if (!e.model.isNew()) { // set to current valuet
//instrDropDown.text(e.model.InstrumentName); // not working...
instrDropDown.select(1);
//portfDropDown.text();
}
},
filterable: true,
sortable: true,
pageable: true,
editable: "popup",
});
Here's my Editor Template for the dropdown:
function instrumentsDropDownEditor(container, options) {
// INIT INSTRUMENT DROPDOWN !
var dropDown = $('<input id="InstrumentName" name="InstrumentName">');
dropDown.appendTo(container);
dropDown.kendoDropDownList({
dataTextField: "name",
dataValueField: "id",
dataSource: {
type: "json",
transport: {
read: "/api/breeze/GetInstruments"
},
},
pageSize: 6,
select: onSelect,
change: function () { },
optionLabel: "Choose an instrument"
}).appendTo(container);
}
thanks a lot

Your editor configuration is bit unlucky for grid, anyway i have updated my ans on provided code avoiding manual selections:
Assumptions: Instrument dropdown editor only (leaving other fields as strings), Dummy data for grid

Kendo UI toolbar buttons

I am using a Kendo UI grid, which looks like this:
function refreshGrid()
{
$(".k-pager-refresh.k-link").click();
}
var editWindow;
var fields= {FullName: {type: "string"}, Email: {type: "string"}, LogCreateDate: {type: "date"}};
var gridColumns =
[{
width: 90,
command: {
name: "edit",
text: "Edit",
click: function(e) {
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
editWindow = $("#edit").kendoWindow({
title: "Edit User",
modal: true,
visible: false,
resizable: false,
width: 800,
height: 400,
content: 'myediturl' + dataItem.ID
});
editWindow.data("kendoWindow").center().open();
return false;
}
}
},
{
width: 90,
command: {
name: "delete",
text: "Delete",
click: function(e) {
//alert(this.dataItem($(e.currentTarget).closest("tr")).ID);
var id = this.dataItem($(e.currentTarget).closest("tr")).ID;
if (confirm("Are you sure you want to delete this user?"))
{
$.ajax({
type: 'POST',
url: '#Url.Action("deleteuser","admin",null, "http")' + "/" + this.dataItem($(e.currentTarget).closest("tr")).ID,
success: function (param) { refreshGrid(); },
async: false
});
}
return false;
}
}
},
{
field: "FullName",
title: "Full Name",
type: "string"
},
{
field: "Email",
title: "Email",
type: "string"
},
{
field: "LogCreateDate",
title: "Created",
type: "date",
template: '#= kendo.toString(LogCreateDate,"MM/dd/yyyy") #'
}];
//getSorts the columns of the grid
function getColumns() {
//Parsing the set of columns into a more digestable form
var columns = "";
for (var col in gridColumns) {
if (!!gridColumns[col].field)
{
if (columns.length > 0) {
columns += ";";
}
columns += gridColumns[col].field + "," + gridColumns[col].type;
}
}
return columns;
}
function getSorts(sortObject) {
if (!(sortObject)) {
return "";
}
//Getting the row sort object
var arr = sortObject;
if ((arr) && (arr.length == 0)) {
return "";
}
//Parsing the sort object into a more digestable form
var columnSet = getColumns();
var returnValue = "";
for (var index in arr) {
var type = "";
for (var col in gridColumns) {
if (gridColumns[col].field === arr[index].field) {
type = gridColumns[col].type;
}
}
returnValue += ((returnValue.length > 0) ? (";") : ("")) + arr[index].field + "," + (arr[index].dir === "asc") + "," + type;
}
return returnValue;
}
var grid;
$(function () {
$("#grid").kendoGrid({
dataSource: {
transport: {
read: {
url: "mydatasourceurl",
type: "POST",
},
parameterMap: function (data, type) {
data.filters = JSON.stringify(data.filter);
data.columns = JSON.stringify(getColumns());
data.sorts = JSON.stringify(getSorts(data.sort));
console.log(data);
return data;
}
},
schema: {
fields: fields,
data: "Data",
total: "Total"
},
pageSize: 10,
serverPaging: true,
serverFiltering: true,
serverSorting: true
},
toolbar: [{
name: "Add",
text: "Add new record",
click: function(e){console.log("foo"); return false;}
}],
height: 392,
groupable: false,
sortable: true,
filterable: true,
pageable: {
refresh: true,
pageSizes: true
},
columns: gridColumns
});
grid = $("#grid").data("kendoGrid");
});
My create toolbar action is not triggered on click. How can I resolve this problem, is Kendo UI able to handle toolbar click events? The best solution I came up with looks like this:
$(".k-button.k-button-icontext.k-grid-add").click(function () {
//If the window doesn't exist yet, we create and initialize it
if (!grids[gridContainerID].addWindow.data("kendoWindow")) {
grids[gridContainerID].addWindow.kendoWindow({
title: "Add " + entityName,
width: "60%",
height: "60%",
close: onClose,
open: onAddOpen,
content: addUrl
});
}
//Otherwise we just open it
else {
grids[gridContainerID].addWindow.data("kendoWindow").open();
}
//Centralizing and refreshing to prepare the layout
grids[gridContainerID].addWindow.data("kendoWindow").center();
grids[gridContainerID].addWindow.data("kendoWindow").refresh();
return false;
});
Thanks in advance.
Instead of using that complex selector use the one that Kendo UI creates from name:
toolbar: [
{
name: "Add",
text: "Add new record",
click: function(e){console.log("foo"); return false;}
}
],
and then:
$(".k-grid-Add", "#grid").bind("click", function (ev) {
// your code
alert("Hello");
});
In kendogrid docs here shows that there is no click configuration for grid toolbar buttons like grid.colums.commands.
To solve this problem you can reference following steps:
create a template for toolbar
<script id="grid_toolbar" type="text/x-kendo-template">
<button class="k-button" id="grid_toolbar_queryBtn">Query</button>
</script>
apply tempate to toolbar
toolbar:[{text:"",template: kendo.template($("#grid_toolbar").html())}]
add event listener to button
$("#grid_toolbar_queryBtn").click(function(e) {
console.log("[DEBUG MESSAGE] ", "query button clicked!");
});
