jsGrid is not working correctly with data loading page by page

I am trying to get jsGrid working in a project but I am missing something since I can't make it to work correctly. I have read docs carefully several times.
The scenario is as follow:
An AJAX call for get a list of subregion
An AJAX call for get a list of countries (each time I click on pagination a new request should be made in order to get proper values)
From docs under controller section:
loadData is a function returning an array of data or jQuery promise
that will be resolved with an array of data (when pageLoading is true
instead of object the structure { data: [items], itemsCount: [total
items count] } should be returned). Accepts filter parameter including
current filter options and paging parameters when pageLoading is true.
So my PHP function return data in the "proper" format as expected, meaning:
{
data: [items],
itemsCount: [total items count]
}
I have created a Pastebin with the result I get when the AJAX call is made (for the countries result). I believe the data is right now. So, this is how my code looks like:
$(function () {
$.ajax({
type: "GET",
url: "/adminconsolejsgrid/subregion"
}).done(function (subregion) {
$("#jsGrid").jsGrid({
height: "70%",
width: "100%",
filtering: true,
sorting: true,
paging: true,
autoload: true,
pageSize: 15,
pageButtonCount: 5,
pageLoading: true,
controller: {
loadData: function (filter) {
return $.ajax({
type: "GET",
url: "/adminconsolejsgrid/countries",
data: filter
});
}
},
fields: [
{name: "country_name", title: "Name", type: "text", width: 100, sorting: true},
{name: "country_abbr", title: "Code", type: "text", width: 5, sorting: true},
{
name: "subregion",
title: "SubRegion",
type: "select",
width: 100,
items: subregion,
valueField: "subregion_id",
textField: "subregion_name"
},
{type: "control"}
]
});
});
});
But still not working for me which mean I am not getting any values on the grid. This pic is an example of what I get:
What I am missing? Any help?

Kendo UI grid export excel and pdf export, no file created

I am trying to create a kendo grid with excel export. My data is shown precisely as I want it and the grid works fine. However, the saveAsExcel function triggers the excelExport event, but no file is created. Same problem with the pdf export.
Here is my grid options:
grid = $("#grid").kendoGrid({
toolbar:["excel","pdf"],
height: 500,
scrollable: true,
groupable: true,
sortable: true,
filterable: false,
excel: {
allPages:true,
filterable:true
},
excelExport: function(e) {
console.log('Firing Export');
console.log(e.workbook);
console.log(e.data);
},
pdfExport: function(e){
console.log('PDF export');
},
columns: [
{ field: "date", title: "Time", template: "#= kendo.toString(kendo.parseDate(date), 'MM/dd/yyyy') #", width: '120px'},
{ field: "customer", title: "Customer" },
{ field: "amount", title: "Total", format: "{0:c}", width: '70px', aggregates: ["sum"]},
{ field: "paid_with", title: "Payment", width: '130px'},
{ field: "source", title: "Source" },
{ field: "sale_location", title: "Sale Location" }
]
}).data("kendoGrid");
This ajax is called whenever the search parameters for the data is changed. Where I refresh the datasource.
$.ajax({
'url':'/POS/ajax/loadTransactionsDetailsForDay.php',
'data':{
filters
},
'type':'GET',
'dataType':'json',
'success':function(response) {
var dataSource = new kendo.data.DataSource({
data: response.data.invoices,
pageSize: 100000,
schema: {
model: {
fields: {
date: {type: "string"},
customer: { type: "string" },
amount: { type: "number" },
paid_with: {type: "string"},
source: {type:"string"},
sale_location: {type:"string" }
}
}
}
});
grid.setDataSource(dataSource);
grid.refresh();
}
});
The output from my console log is.
Firing Export.
A worksheet object.
Object {sheets: Array[1]}sheets: Array[1]0: Objectlength: 1__proto__: Array[0]__proto__: Object
and and array with these objects for every row in the grid:
0: o
_events: Object
_handlers: Object
amount: 40.45
customer: "customer 1"
date: "2015-11-25T00:00:00-08:00"
dirty: false
employee: 23
paid_with: "Check"
parent: ()
sale_location: "Main"
source: "POS"
uid: "70b2ba9c-15f7-4ac3-bea5-f1f2e3c800d3"
I have the latest version of kendo, I am loading jszip. I am running it on the latest version of chrome.
I have tried all kinds of variations of this code I can think of, including removing my schema, initializing the kendo anew every time in the callback.
Anyone got any idea why this would not work?
Every example on this I can find make it look super simple, just create the grid and call export... So I have to have overlooked something.
I am grateful for any ideas about this.
Thanks.

It could be because the filename is missing.
Here the part with the filename added:
excel: {
allPages:true,
filterable:true,
fileName: "Kendo UI Grid Export.xlsx"
},
You can take a look here : Grid Excel Export
And here for the pdf: Grid Pdf Export

I have some following suggestion.
Can you add kendo deflate pako script file into your code and try.
Then remove the pdf export event and just try to export a pdf with toolbar default functionality..check whether its working or not.
try to add a data-source ajax call with in a grid option using kendo-transport technique with read method. http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-transport

Why Kendo dataSouce.transport.update method do not send data to the server?

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.

How to load extjs 4 grid data on form submission?

I am new to ExtJS.
I am developing a page which has a form at the top and a grid below. When user enters the search criteria in the form and enters Submit, grid has to be populated with data accordingly.
I have managed to get the JSON data from server to the client
console.log('response.responseText');
prints the data correctly, but unable to assign that to the grid.
Here is my code
Ext.define('colModel', {
extend: 'Ext.data.ColumnModel',
fields: [
'personId',
'country',
'idType',
'idValue'
]
});
// create the data store
var store = Ext.create('Ext.data.ArrayStore', {
model: 'colModel',
fields: [
{name: 'personId'},
{name: 'country'},
{name: 'idType'},
{name: 'idValue'}
],
proxy: {
type: 'ajax',
reader: {
type: 'json',
root: 'person'
}
},
autoLoad: false,
});
// create the Grid
var grid = Ext.create('Ext.grid.Panel', {
store: store,
stateful: true,
id: 'myGrid',
stateId: 'stateGrid',
columns: [
{
text : 'Person Id',
flex : 1,
sortable : false,
dataIndex: 'personId'
},
{
text : 'Country',
width : 75,
sortable : true,
dataIndex: 'country'
},
{
text : 'ID Type',
width : 75,
sortable : true,
dataIndex: 'idType'
},
{
text : 'Id Value',
width : 75,
sortable : true,
dataIndex: 'idValue'
},
],
height: 350,
title: 'Array Grid',
renderTo: 'bottom',
viewConfig: {
stripeRows: true,
ForceFit: true,
loadMask:false
}
});
and this function get invoked after form submission and response returned from server
displayGrid : function(response, opts) {
//Received response from the server
console.log('On Success');
responseData = Ext.decode(response.responseText);
console.log('response success ',responseData);
console.log(Ext.getCmp('myGrid').getStore());
grid.getStore().loadData('colModel',false);
}
I have managed to populate grid data on page load using the following code
var store = Ext.create('Ext.data.ArrayStore', {
model: 'colModel',
proxy: {
type: 'rest',
url : 'PersonSearch',
reader: {
type: 'json',
root: 'person'
}
},
autoLoad: true
});
but failed to load grid data on form submission.
Please help. Thanks in advance.
PS: I am using ExtJS 4.2
Update
This is the JSON update, I am getting from the server(caught using Firefox Browser Console)
"{"person":[{"personId":"1","country":"country 1","idType":"idType 1","idValue":"idValue 1"},{"personId":"2","country":"country 2","idType":"idType 2","idValue":"idValue 2"},{"personId":"3","country":"country 3","idType":"idType 3","idValue":"idValue 3"},{"personId":"4","country":"country 4","idType":"idType 4","idValue":"idValue 4"},{"personId":"5","country":"country 5","idType":"idType 5","idValue":"idValue 5"}]}
"

You aren't actually loading the data. Your data is stored in responseData, so your loadData call should load that data into the store. So, your loadData call should be as follows:
grid.getStore().loadData(responseData);
Note that this assumes that your responseData is in the correct format for the store you are loading it into. (Also note that the second parameter is false by default, so it isn't necessary to include it in this case)

Used forgivenson comment and set autoLoad: true
and
Updated the displayGrid method as below
displayGrid : function(response, opts) {
//Received response from the server
console.log('On Success');
responseData = Ext.decode(response.responseText,false);
console.log(response.responseText);
grid.getStore().loadData(responseData.person);
}
and the grid gets populated correctly.

ExtJS grid filters: how can I load 'list' filter options from external json?

I have a ExtJS (4.0) grid and it works fine. Now I want it to advance it a bit by adding filters to it. I want users to be able to filter items by the status.
I have created the following store:
var status_store = Ext.create('Ext.data.Store', {
model: 'Statuses',
proxy: {
type: 'ajax',
url: '/json/statuses/',
reader: 'json'
}
});
and I can see it loads, /json/statuses/ will return the following json object:
[
{
"name": "OK",
"isActive": true
},
{
"name": "Outdated",
"isActive": true
},
{
"name": "New",
"isActive": true
}
]
Now I define the filters:
var filters = {
ftype: 'filters',
encode: encode,
local: local,
filters: [{
type: 'list',
dataIndex: 'name',
store: 'status_store',
labelField: 'name'
}]
};
and add the filter to my column definition:
{text: 'Status', width: 120, dataIndex: 'status', sortable: true, filterable: true, filter: {type: 'list'}},
What happens is I get the following error when the grid loads:
Uncaught TypeError: Object json has no method 'read' (ext-all-debug.js:25702)
and when I click on the column header for the menu:
Uncaught TypeError: Object status_store has no method 'on' (ListMenu.js:69)
How can I fix this or am I doing something conceptually wrong?
Here is the full quote of my code just in case: http://pastebin.com/SNn6gFJz

Thanks for Diagnosing the problem. The 4.1 fix is this modify ListMenu.js
in the else part of the constructor
replace
me.store.on('load', me.onLoad, me);
with
// add a listener to the store object
var storeObject = Ext.StoreMgr.lookup(me.store);
storeObject.on('load', me.onLoad, me);
me.store = storeObject;

filters: [{
type: 'list',
dataIndex: 'name',
store: 'status_store',
labelField: 'name' ,
options:[a,b]
}]
You also have to give the options in list filters.

I was having a similar problem. I followed the #jd comment on the other answer here but the options menu just said "loading...". I resolved it with a bit of a hack here.
