I'm trying to update column's setting in Handsontable like this:
var newColumnSettings = [{ data: 0, readOnly: true }, { data: 1 }, { data: 2 }, { data: 3 }, { data: 4, readOnly: true }];
$('#container').handsontable('updateSettings', { columns: newColumnSettings });
But it simply does not work and nothing happens, and handsontable still shows the older columns.
Should I do something before or after? Am I doing something wrong?
Thanks in advance.
Have you tried to rerender the table after your updateSettings?
var newColumnSettings = [{ data: 0, readOnly: true }, { data: 1 }, { data: 2 }, { data: 3 }, { data: 4, readOnly: true }];
var ht = $('#container').handsontable('getInstance');
ht.updateSettings({ columns: newColumnSettings });
ht.render();
See if that helps

I would like to implement a simple line graph with ajax in which only two points
x will be the hours and y will be the count of calls.
CODE :
<script>
function getData() {
$.ajax({
type:'POST',
url: "http://localhost/demo_chart/test.php",
dataType: 'JSON',
success: function(response_data) {
new_data = $.map(response_data, function(i){
return {x: i['date'],y: i['count']};
});
$('#container').highcharts({
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'Count vs. Time'
},
xAxis: {
title: {
text: 'Time'
},
type: 'Time',
},
yAxis: {
title: {
text: 'Count'
}
},
series: [{
name: 'Test',
data: new_data
}]
});
}
})
}
$(document).ready(function () {
getData();
})
</script>
Output of http://localhost/demo_chart/test.php is same as below :
{"date":["13:00:00","13:00:01","13:00:02","13:00:03","13:00:04"],"count":["1","2","3","4","2"]}
But still graph is not generating. So i would like to know what is the problem here.
Anyone like to share some hint which can resolve this problem ?
Expected output is :
X- axis : show all date
Y-axis : show count
You need to correct your mapping function, for example:
var response = {
"date": ["13:00:00", "13:00:01", "13:00:02", "13:00:03", "13:00:04"],
"count": ["1", "2", "3", "4", "2"]
};
new_data = $.map(response.date, function(el, index) {
return {
name: el,
y: parseInt(response['count'][index])
};
});
Additionally, with that data structure, I recommend you to use category axis type.
xAxis: {
...,
type: 'category'
}

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
So, I'm trying to make a readyonly grid with kendo that shows data, but whatever I do, the data does not get shown.
The grid looks like this
And here's the code:
$("#Materials")
.kendoGrid({
dataSource: {
data: [],
schema: {
model: {
id: "ID",
fields: {
ID: { type: "number", editable: false },
Code: { type: "string", editable: false },
Name: { type: "string", editable: false },
ExtDeviceCode: { type: "string", editable: false , nullable: true },
BaseUomLOVString: { type: "string", editable: false }
}
}
},
pageSize: 20
},
filterable: {
extra: true
},
pageable: true,
columns: [
{ field: "Code", title:"Code"},
{ field: "Name", title: "Name"},
{ field: "ExtDeviceCode", title:"External device code"},
{ field: "BaseUomLOVString", title: "UnitsOfMeasure" }
],
editable: false
});
This makes an empty grid with no data, which I later on fill with an Ajax call. As you can see from above picture, the grid contains the data but does not display it. The data inside the dataSource looks like this. or as Json:
[{
"ID": 21150,
"Code": "3",
"ExtDeviceCode": null,
"Name": "Avio benzin",
"BaseUomLOVString": "Kilogram"
}, {
"ID": 21400,
"Code": "5003",
"ExtDeviceCode": null,
"Name": "Bencin 95",
"BaseUomLOVString": "Litre"
}]
EDIT 1: I'm filling the data with an Ajax call like this:
$.ajax({
url: '#SimpleUrlHelper.UrlObjectToRoot(Url)/FuelPointMaterialTankMask/LookupMaterials',
data: {
//Send list of IDs
'materialIDs': materialList
},
type: "POST",
success: function (response) {
var tmp = [];
if (typeof response !== "undefined" &&
response !== null) {
response.forEach(function(item) {
tmp.push(item);
});
}
grid = $("#Materials").data("kendoGrid");
originalMaterialDataSource = grid.dataSource;
originalMaterialDataSource.data(tmp);
originalMaterialDataSource._destroyed = [];
originalMaterialDataSource.pageSize(pageSize);
originalMaterialDataSource.page(1);
originalMaterialDataSource._total = tmp.length;
grid.pager.refresh();
}
});
You can set your data in your dataSource after your ajax call.
var dataArray = [{
"ID": 21150,
"Code": "3",
"ExtDeviceCode": null,
"Name": "Avio benzin",
"BaseUomLOVString": "Kilogram"
}, {
"ID": 21400,
"Code": "5003",
"ExtDeviceCode": null,
"Name": "Bencin 95",
"BaseUomLOVString": "Litre"
}];
Use .data() to set:
$("#Materials").data('kendoGrid').dataSource.data(dataArray );
Okay so after days of trying to figure out what was wrong I finally found the answer.
Somewhere along the lines I had:
var grids = $('.k-grid');
for (var i = 0; i < grids.length; i++) {
....
grid.dataSource.filter().filters[0] = {
logic: "or",
filters: filters
}
....
So basically I was putting filters on all grids without excluding this one, which was just a bug from my part.
I am a beginner working on Kendo Grid. I wanted to load the data on demand in the grid, like :
I set the page size to 10, when a user scrolls down to 10 rows, the
grid should retrieve next 10 rows from database and display it on
demand.To do this, I changed "scrollable: true" to "scrollable: {virtual: true}". But this disables scrolling in the grid.
$scope.source = new kendo.data.DataSource({
batch: true,
group: getDSGroup(),
transport: {
read: userSvc.getUserList,
update: _dataUpdateItem
},
error: function(e) {
ngDialog.openConfirm({
template: 'httpErrorDialogId',
className: 'ngdialog-theme-default',
data: {
'status': e.status,
'message': e.errorThrown
}
});
},
schema: {
parse: function(data) {
$rootScope.$log.log("User list was fetched.");
if ($rootScope.sysSettings.userMgr_serverPaging)
return data;
for (var i = 0; i < data.items.length; i++) {
data.items[i].letter = data.items[i].lastName.substr(0, 1).toUpperCase();
if (data.items[i].departmentName == null) data.items[i].departmentName = $rootScope.$translate.instant("Unassigned");
if (data.items[i].userGroupName == null) data.items[i].userGroupName = $rootScope.$translate.instant("Unassigned");
}
return data;
},
model: {
id: "id"
},
groups: "groups",
total: "totalItems",
data: "items"
},
filter: getDSFilter(),
sort: getDSSort(),
pageSize: $rootScope.sysSettings.userMgr_serverPaging ? 10 : 0,
serverGrouping: $rootScope.sysSettings.userMgr_serverPaging,
serverPaging: true,
serverSorting: $rootScope.sysSettings.userMgr_serverPaging,
serverFiltering: $rootScope.sysSettings.userMgr_serverPaging
});
$scope.userListOptions = {
//sortable: true,
groupable: true,
selectable: false,
//pageable: true,
scrollable: {
virtual: true
},
//dataBound: function() {
// this.expandRow(this.tbody.find("tr.k-master-row").first());
//},
columns: [{
field: "firstName",
template: kendo.template($("#tpl-UserItem").html())
}, {
field: "letter",
hidden: true,
groupHeaderTemplate: "#= value #"
}]
};
$scope.isEndlessScroll = function() {
return $rootScope.sysSettings.userMgr_serverPaging;
};
If your grid is is being created while is invisible, the connfiguration is a bit diffrent.

hope this help
first I thought it is a simple problem however I could not solve it anyway.
I have a extjs gridpanel, its store and model. From controller, I can insert new records to store, when I use firebug and debug, I can list all the new records in the store (panel.store.data.items) however in the gridview I cannot make it visible.
Could you please tell me where and what I am missing? Why the records are not listed in the grid?
This is my model
Ext.define('BOM.model.PaketModel', {
extend: 'Ext.data.Model',
fields: [
{ name: 'seriNo', type: 'string' },
{ name: 'tutar', type: 'string' },
]
});
This is store
Ext.define('BOM.store.PaketStore', {
extend: 'Ext.data.Store',
model: 'BOM.model.PaketModel',
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'data',
},
writer: {
type: 'json',
root: 'data',
},
},
});
This is the method I add new rows
addNew: function () {
this.getPaketWindow().returnRowEdit().cancelEdit();
this.getPaketWindow().getStore().insert(0, new BOM.model.PaketModel());
this.getPaketWindow().returnRowEdit().startEdit(0, 0);
}
UPDATE VIEW
Ext.define('BOM.view.PaketCreate', {
extend: 'Ext.grid.Panel',
alias: 'widget.paketcreate',
bodyPadding: 5,
layout: 'fit',
header:false,
initComponent: function () {
this.columns = [
{ text: 'Seri No', flex: 2, sortable: true, dataIndex: 'seriNo', field: {xtype: 'textfield'} },
{ text: 'Tutar', flex: 2, sortable: true, dataIndex: 'tutar', field: {xtype: 'textfield'} }
];
this.dockedItems = [{
xtype: 'toolbar',
items: [{
text: 'Ekle',
id:'addNewCheck',
iconCls: 'icon-add',
},'-',{
id: 'deleteCheck',
text: 'Sil',
iconCls: 'icon-delete',
disabled: true,
}]
}];
this.store = 'BOM.store.PaketStore';
rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false
});
this.plugins = rowEditing,
this.callParent(arguments);
},
returnRowEdit: function () {
console.log("row editing...");
return rowEditing;
}
});
var rowEditing;
Try:
this.store = Ext.create('BOM.store.PaketStore');
instead of:
this.store = 'BOM.store.PaketStore';
http://jsfiddle.net/qzMb7/1/
It works when I add ".getView()" like
this.getPaketWindow().getView().getStore().insert(0, new BOM.model.PaketModel())
However, I still do not understand. Both reaches the same store when I add records manually I can see them in the store.data but it is visible only if I include .getView() part
