I am having trouble saving changes using to the server using Kendo UI Listview.
The DataSource is configured like this:
var listViewDataSource = new kendo.data.DataSource({
transport: {
read: {
url: MyServiceURL
},
update: function() {
console.log("test"); // I expected to enter this function
// when the user changes data on the
//client, never happens
}
},
schema: {
Id: "Id",
fields: {
DeptName: {
editable: false,
},
HourRate: {
type: "number",
editable: true
},
ShowOnSavings: {
type: "boolean",
editable: true
},
ShowOnTechnicalCosts: {
type: "boolean",
editable: true
},
ShowOnOtherCosts: {
type: "boolean",
editable: true
}
}
},
sync: function (e) {
console.log("item synched"); //This should be fired after the
// updated data is sent, never
//happens
}
The ListView is initialised like this:
kendo.bind($("#listview-container"), {
listViewDataSource: listViewDataSource,
onItemSaved: function (e) {
console.log("item saved"); // fired every time the user changes
//an item, as expected
}
})
The ListView properly loads the data. When the user edits an item the change is visible locally (after leaving edit mode) and the save event is fired, as expected.
However the changes are never synchronized with the server, my update method is never called and no network activity is never called.
The documentation on the ListView save method states the following:
Saves edited ListView item. Triggers save event. If save event is not prevented and validation succeeds will call DataSource sync method.
As I don't call preventDefaulton the save event I expect the data sourve to sync, however this does not happen. Calling dataSource.sync() manually does not help either.
I am puzzled why this does not work. Any tips appreciated.
I skipped one level of nesting in the model configuration, model was missing
schema: {
model: {
id: "Id",
fields: {
Id: {
type: "number",
editable: false
},
DeptName: {
type: "string",
editable: false
},
HourRate: {
type: "number",
editable: true
},
ShowOnSavings: {
type: "boolean",
editable: true
},
ShowOnTechnicalCosts: {
type: "boolean",
editable: true
},
ShowOnOtherCosts: {
type: "boolean",
editable: true
}
}
}
}

in my project i want to initialize Kendo Grid from jquery file. i have created a .js file in which i have created a function
function initializeGrid(gridName, url, onSelectFunction) {
onSelectFunction = onSelectFunction || null;
$("#" + gridName).kendoGrid({
dataSource: {
type: "json",
transport: {
read: url
},
schema: {
model: {
fields: {
ClientID: {type: "number"},
Client:{type: "string"}
}
}
},
pagesize: 30,
Paging: true,
Filtering: true,
},
selectable: "multiple cell",
filterable: true,
columns: [
{ field: "ClientID" },
{ Template: ("<input type='checkbox' id='#:data.ClientID#' class='k-checkbox'/><label class='k-checkbox-label' onclick='event.stopPropagation()' for='#:data.ClientID#'></label>") },
{ field: "Client" }
]
});
$("#" + gridName).attr("data-val-number", "Invalid input.");
}
this function accepts name of the control and url to load data source from as arguments. in another .js file i have all code that loads controls by calling the earlier function.
initializeGrid("client", "/Clients/GetDataForGrid", null);
issue is that when i run the program it is not creating the grid and loading the data instead showing a drop down with no data. i checked http://docs.telerik.com/kendo-ui/api/javascript/ui/grid?utm_medium=social-owned&linkId=38973492 for reference but no use.
i would really appreciate help here.
i am working on lightswitch project ,and I am using JsGrid.I ran into one problem and I don't couldn't find the solution.here is the scenario:
I use the grid to get data from database table,when I update one of the cell It's value doesn't appear unless I click on the cell again,and if I update it in the second time then the new value appear.
I tried to refresh the grid after itemupdated but still the new value doesn't appear instantaneously.my code is here:
$("#jsGrid").jsGrid({
width: "100%",
height: "auto",
inserting: true,
editing: true,
sorting: true,
paging: true,
autoload: true,
controller: {
loadData: function () {
var deferred = jQuery.Deferred();
myapp.activeDataWorkspace.ApplicationData.Table1Items.load().done(function (data) {
deferred.resolve(data.results);
});
return deferred.promise();
},
updateData: function () {
$("#jsGrid").jsGrid("refresh");
},
deleteItem: function (Item) {
$("#jsGrid").jsGrid("refresh");
}
},
fields: [
{ name: "EmployeeName", type: "text", width: 150 },
{ name: "Points", type: "text", width: 200 },
{ type: "control", editButton: true, // show edit button
deleteButton: true, // show delete button
clearFilterButton: true, // show clear filter button
modeSwitchButton: true // show switching filtering/inserting button
}]
,
onItemInserted: function (item) {
}, onItemUpdating: function (item) {
$("#jsGrid").jsGrid("refresh");
},
onItemUpdated: function (item)
{
$("#jsGrid").jsGrid("refresh");
console.log("it is updated", item.item);
$("#jsGrid").jsGrid("refresh");
}
});
your help is invaluable and many thanks in advance.
hope this may help you. updateItem is a function returning updated item or jQuery promise that will be resolved with updated item. Accepts updating item object.
on successful updating Item, use
updateItem: function(item) {
return $.ajax({
type: "PUT",
url: "/items",
data: item
});
},
if you have any queries, comment below.

I have Kendo Combobox in that on Change event I am calling a controllers action using Jquery Ajax.For the first time on Select of any item from Combobox the Action is called and I get the required data.
But on ComboxBox focus Out(When i click on any where on the screen) the same action is being called.
My Kendo Combobox is as follows:
$("#Number").kendoComboBox({
dataTextField: "NUM",
dataValueField: "ID",
dataSource: new kendo.data.DataSource({
transport: {
read: {
url: ResolveUrl("/CreateMaintainAnalysis/GetAnalysisNumbers/"),
type: "POST",
dataType: "json",
data: function () {
return {
Number: $("#Number").data("kendoComboBox").input.val()
};
}
},
},
requestEnd: function (e) {
if (WebApp.CLAF.LoggedInUser.Info.IS_ANALYST == 'Y') {
e.response.unshift({ ID: -1, NUM: 'Create New Analysis' });
}
else {
e.response.unshift({ ID: -2, NUM: 'Select' });
}
},
serverFiltering: true
}),
filter: "startwith",
suggest: true,
minLength: 5,
highlightFirst: true,
index:0,
change: function (dataItem) {
$.ajax({
type: "POST",
data: { ID: ID },
url: ResolveUrl("/Analysis/Data"),
success: function (result) {
},
});
}
});
This is really very weird behavior and I am not able to catch it up.
Inside dataSource please add autoBind: false, this is by default true, and most often this is the reason for sending an additional API call from inside upon any focus in/out or click events.
I have a Kendo UI TreeList where every row has a checkbox displayed. If the user clicks on the checkbox then a request goes to the server and save the data. Unfortunately, I did something wrong because:
the update method does not send data to the server
and the sync method is not called automatically
What I did wrong?
I think the problem around how I set up that which item has changed. As you can see I iterate over the dataset coming from dataSource.data() and the item.checked and item.dirty properties are updated. If I understand correctly the documentation then this changes should trigger the sync method. It does not trigger the sync method and this it the reason I call it in the method.
My other question is related to the data structure should be sent to the server. It is based on the schema, right? So, once I can achieve that the request sends an object to the server I should create a similar C# POCO as model and I can read the data in the webapi controller.
In the documentation there is a saveRow() method, but I cannot translate that code to angular. Can somebody help me in this case?
//this row is my problem
var treeList = $("#treeList").data("kendoTreeList");
var dataSource = new kendo.data.TreeListDataSource({
transport: {
read: {
url: configurationService.goNoGoWebApiRootUrl + 'AreaPathDependencies/Get/ChildrenMarked/' + selectedAreaPathIdFromModalService,
dataType: "json",
type: "get"
},
update:
{
url: configurationService.goNoGoWebApiRootUrl + 'AreaPathDependencies/Update/AreaPathDependencies',
dataType: "json",
type: "post"
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}
},
schema: {
model: {
id: "id",
parentId: "parentId",
fields: {
Id: { type: "number", editable: false, nullable: true },
ParentId: { type: "number", editable: false, nullable: true },
Name: { type: "string", editable: false, nullable: true },
Checked: { type: "boolean", editable: true, nullable: false }
}
}
}
});
vm.treeListOptions = {
dataSource: dataSource,
sortable: false,
editable: false,
columns: [
{
field: "checked",
title: "Selected",
template: checkBoxTemplate,
width: 32
},
{ field: "name", title: "Area Path", width: "200px", expandable: true },
{ field: "fullPath", title: "FullPath", width: "500px" },
],
save: onSave,
change: onChange,
sync: sync,
autoSync: true,
};
}
function checkboxOnclick(selectedId) {
console.log('checkboxOnclick', selectedId);
var data = vm.treeListOptions.dataSource.data();
for (var i = 0; i < data.length; i++) {
if (selectedId == data[i].id) {
data[i].set("checked", true);
//data[i].dirty = true;
}
}
vm.treeListOptions.dataSource.sync();
//console.log('flush', vm.treeListOptions.dataSource.data());
}
Well batch: true has to be set to get parameterMap working, because models parameters will be available only when the batch option is enabled. (parameterMap docs)
And to second question - I am not so sure but as noted in sync docs,
The sync method will request the remote service if:
the transport.create option is set and the data source contains new data items
the transport.destroy option is set and data items have been removed from the data source
the transport.update option is set and the data source contains updated data items
How I understand to that - to get sync method working you need to return updated records. Please check, if your server method for update/delete returns that.
I am using this html code for Keno UI grid
function loadPhoneGrid(salesRepsId){
$("#phone-grid").kendoGrid({
dataSource: {
transport: {
read: {
url: "operations/get_phones_sales_reps.php?salesRepsId="+salesRepsId,
type: "GET"
},
update: {
url: "operations/edit_phone_number.php?salesRepsId="+salesRepsId,
type: "POST"
},
destroy: {
url: "operations/delete_phone.php",
type: "POST"
},
create: {
url: "operations/add_phone.php?salesRepsId="+salesRepsId,
type: "POST",
},
},
schema: {
data:"data",
total: "data.length", //total amount of records
model: {
id: "PhoneId",
fields: {
PhoneType: { defaultValue: { PhoneTypeId: 1, PhoneTypeName: "Work"} },
PhoneNumber: { type: "string" },
IsMainPhone: {type: "boolean", editalbe:true},
}
}
},
pageSize: 5,
},
height: 250,
filterable: true,
sortable: true,
pageable: true,
reorderable: false,
groupable: false,
batch: true,
toolbar: ["create", "save", "cancel"],
editable: true,
columns: [
{
field:"PhoneType",
title:"Type",
editor: PhoneTypeDropDownEditor,
template: "#=PhoneType.PhoneTypeName#"
},
{
field: "PhoneNumber",
title:"Phone Number",
},
{
field: "IsMainPhone",
title:"Is Main",
width: 65,
template: function (e){
if(e.IsMainPhone== true){
return '<img align="center" src ="images/check-icon.png" />';
}else{
return '';
}
}
// hidden: true
},
{ command: "destroy", title: " ", width: 90 },
],
});
}
The code in the server side is (add_phone.php)
<?php
require_once("../lib/Phone.php");
$phone = array();
foreach($_POST as $name => $value){
$phone[$name] = $value;
}
Phone::AddPhoneNumber($_GET["salesRepsId"], $phone);
?>
For the first time, I added a new record. add_phone.php is calling once and everything is working fine. For the second time (with out refresh the page) when I try to add a new record, add_phone.php is called twice. One of them contains the first record which has been added to database before and the second is the new the data.
in the result I have 3 records ( 2 same data of first insert) and one new.
This an example to make it clear ( inspect the post request with firebug)
first click on save button (false, (111) 111-1111, 4,Fax) // after I enter this phone (111) 111-1111
second click on save button (false, (111) 111-1111, 4,Fax) in addition to (false, (222) 222-2222, 3,Work) // after I added this (222) 222-2222
Any help ??
May be your ajax request raise an error. You can see it by subscribing to the error event of your datasource.
In case of error, the data are not synchronized in your datasource. In your case, I think your dataitem stay in "dirty mode" so the datasource try to insert them for each synchronization...
