I have a Kendo Pie chart in a js file,it has a onSeriesClick function :
function pieChartForInterventions(chartID, pieChartData, seriesClickCallback) {
chartID.kendoChart({
dataSource: {
data: pieChartData
},
series: [{
type: "pie",
color: "#FDB45C",
animation: {
type: "fadeIn",
duration: 100
},
field: "list",
categoryField: "mm",
padding: 0,
labels: {
visible: true,
},
overlay: {
gradient: "none"
},
}],
seriesColors: ["#46BFBD", "lightskyblue"],
tooltip: {
visible: true,
template: "${ category }"
}
,
legend: {
position: "bottom"
},
seriesClick: seriesClickCallback
});
}
I supply it with data,and and created me a a pie chart,in the pie chart,when i click it should give me a grid and another chart(column),when there is only grid,it works,when i want both grid and column chart,seriesClick event does not work after first call,for grid and column chart i have two different functions,
here is my column chart:
function createChartForInterventions(dataForInter) {
chartID.kendoChart({
legend: {
visible: false
},
series: [{
data:dataForInter,
type: "column",
color: "#FDB45C",
field: "cp_type_present",
categoryField: "turbineName",
}],
});
});
and here is my grid:
function createDynamicGrid(chartId, source, column) {
chartId.kendoGrid({
dataSource: {
data: source,
},
height: 350,
scrollable: true,
sortable: true,
filterable: true,
columns: column,
noRecords: {
template: "No data"
},
});
}
in my main view ,i call them :
$.ajax({
dataType: "json",
type: "POST",
url: "#Url.Action("faultstatCrewPresentIntervetion","Dashbrd")",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ "dtFrom": dtDrpVals.fromDate, "dtTo": dtDrpVals.toDate }),
success: function (result) {
var _clicked;
function onDb(e) {
createDynamicGrid($("#gridProAvail"), result.interInprog, clmns);
createChartForInterventions();
];
}
//Pie Chart
pieChartForInterventions($("#pieChart"), result.nbr_ofCPtype, onDb);
}});
Try change you're event to:
function pieChartForInterventions(chartID, pieChartData, seriesClickCallback) {
chartID.kendoChart({
dataSource: {
data: pieChartData
},
series: [{
type: "pie",
color: "#FDB45C",
animation: {
type: "fadeIn",
duration: 100
},
field: "list",
categoryField: "mm",
padding: 0,
labels: {
visible: true,
},
overlay: {
gradient: "none"
},
}],
seriesColors: ["#46BFBD", "lightskyblue"],
tooltip: {
visible: true,
template: "${ category }"
}
,
legend: {
position: "bottom"
},
.Events(events => events
.SeriesClick("seriesClickCallback")
)
});
}

I have a web API. In that I wrote a update method. But it need to id of the table row to update to the row.
I use a grid to show data and use a toolbar to edit the row.
My question is how I pass that id to the update.
Can someone guide me ??
update: function(options) {
$.ajax( {
url: function(data) { return "updateUsuarios/"+data.Id,
dataType: "json",
.....
Well i suggest you, explain more your question, but i think this examples could help , if you have a toolbar as a template like this:
<script type="text/x-kendo-template" id="template">
<div class="toolbar">
<button type="button" id="update">Update</button>
</div>
</script>
You "grid" need the attr "toolbar"
$("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 550,
filterable:true,
toolbar: kendo.template($("#template").html()),
columns: [
{ field:"username", title: "Username" , width: "120px" },
{ field: "nombre", title:"Nombre", width: "120px" },
{ field: "apellido", title:"Apellido", width: "120px" },
{ field: "ci", title:"Documento de Identidad", width: "120px" },
{ field: "email", title:"Direccion de Correo", width: "120px" },
{ field: "activo",title:"Estatus", width: "120px" },
{ field: "fecha_caducidad",title:"Fin Demo", width: "120px",template: "#= kendo.toString(kendo.parseDate(fecha_caducidad, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" },
{ field: "licencia_status",title:" ", width: "40px",template:'<img src="assets/images/#:data.licencia_status#.png"/>' },
{ command: ["edit"], title: " ", width: "120px" }],
editable: "popup",
dataBound: function () {
var rows = this.items();
$(rows).each(function () {
var index = $(this).index() + 1;
var rowLabel = $(this).find(".row-number");
$(rowLabel).html(index);
});
},
selectable: true
});
So,you can configure a kendo button and add functionality in the event click:
$("#update").kendoButton({
click: function(){
//Here you will have the selected row
var self=$('#grid').data('kendoGrid')
var index = self.items().index(self.select());
var rowActual= self.dataSource.data()[index];
rowActual=self.dataItem(self.select());
if(rowActual==undefined || rowActual ==null) {
alert("No row selected");
}else{
$.ajax({
type: "POST",
url: "update",
data: {
id:rowActual.id
},
dataType: 'json',
success: function (data) {
},
error: function(){
}
});
}
}
});
and send in the ajax the row id, but if you are update the row with the inline edition you could try with a datasource like this
dataSource = new kendo.data.DataSource({
transport: {
read: function(options) {
$.ajax( {
url: "readUsuarios",
dataType: "json",
success: function(result) {
options.success(result);
}
});
},
update: function(options) {
$.ajax( {
url: "updateUsuarios",
dataType: "json",
data: {
models: kendo.stringify(options.data.models)
},
success: function(data) {
// response server;
},
error: function(result) {
// notify the data source that the request failed
options.error(result);
}
});
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "id",
fields: {
username: { editable: false, nullable: true },
nombre: { validation: { required: true } },
apellido: { type: "string", validation: { required: true} },
ci: { type: "string", validation: { required: true} },

activo: { type: "boolean",editable: false },
fecha_caducidad: { type: "date" },
licencia_status:{editable: false}
}
}
}
});
I hope this help!

When I use kendo grid already filtered by parameter like : $('#someGrid').data().kendoGrid.dataSource.read({ activity: value });
i see the get: https://localhost:44305/api/Agencies/?sort=&page=1&pageSize=15&group=&filter=&activity=1
The grid is filter as expected but, when I want to do paging, sorting, refresh - I get the whole data ignoring the filter that i made.
and I see the get: https://localhost:44305/api/Agencies/?sort=&page=1&pageSize=15&group=&filter=
How can I save my filter state to do paging and sorting on the data came from the server side ?
even when i used differen approach like "scrollable: { virtual: true }" and when i scroll down - every request is without the filtering...
Thanks
Did you try
var agenciesData = new kendo.DataToken.DataSource({
filter : function () {
return object;
}
});
I mean try using filter as a function and you can do your logic inside the function depending on the situation.
I am working on a odata grid with Kendo UI.
The problem is that the ajax request keeps containing a callback parameter. Which causes this error: Callback parameter is not supported. When I do the request manually without the callback, my odata service works perfect.
Someone an idea how to fix this?
$("#grid").kendoGrid({
dataSource: new kendo.data.DataSource({
type:"odata",
serverPaging: true,
serverFiltering: true,
serverSorting: true,
transport: {
contentType: "application/json; charset=utf-8",
type: "GET",
read: "/odata/FestivalSignUps?$inlinecount=allpages&$expand=PrefferedTasks/Task,AvailableDays,ApplicationUser",
dataType: "json",
parameterMap: function (options, type) {
var paramMap = kendo.data.transports.odata.parameterMap(options);
delete paramMap.$format; // <-- remove format parameter.
return paramMap;
}
},
pageSize: 10,
schema: {
data: function (data) {
return data["value"];
},
total: function (data) {
return data["odata.count"];
},
}
}),
filterable:true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [
{ field: "ApplicationUser.Email", width: 90, title: "Email" },
{ field: "ApplicationUser.FirstName", width: 90, title: "Voornaam" },
{ field: "ApplicationUser.LastName", width: 90, title: "Achternaam" },
{ field: "PrefferedTasks", width: 90, title: "Taken",
template: "#= formatTasks(data) #"},
{ field: "Beschikbaar", width: 90, title: "Taken" }
]
});
Update
This code solved the problem:
$("#grid").kendoGrid({
dataSource: new kendo.data.DataSource({
type: 'odata',
transport: {
read: {
url: "/odata/FestivalSignUps?$expand=PrefferedTasks/Task,AvailableDays,ApplicationUser",
dataType: "json"
},
},
schema: {
data: function (data) {
return data["value"];
},
total: function (data) {
return data["odata.count"];
},
},
pageSize: 20,
serverPaging: true,
serverFiltering: true,
serverSorting: true
}),
filterable:true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [
{ field: "ApplicationUser.Email", width: 90, title: "Email" },
{ field: "ApplicationUser.FirstName", width: 90, title: "Voornaam" },
{ field: "ApplicationUser.LastName", width: 90, title: "Achternaam" },
{ field: "PrefferedTasks", width: 90, title: "Taken",
template: "#= formatTasks(data) #"},
{
field: "AvailableDays", width: 90, title: "Beschikbaar",
template: "#= formatDays(data) #"
},
]
});
I cover this issue and some others in a blog post that I wrote: Server-Side Filtering Using KendoUI With MVC4 WebAPI and OData.
If you are querying your own data, and don't need to do a cross-domain request, we can just not use jsonp. To do this, we just tell Kendo the dataType for the read operation is "json".
var dataSource = new kendo.data.DataSource({
type: 'odata', // <-- Include OData style params on query string.
transport: {
read: {
url: "/api/Albums",
dataType: "json"; // <-- The default was "jsonp".
}
}
});
Below is my grid.
If you look at the save: event, you'll notice an AJAX call.
This AJAX call IS firing, data IS being inserted into the database and I can even see the alert function going through. However, the grid does not exit edit mode for the row I'm inline editing. I'm not sure what's going on because the error message is terrible. I keep getting:
TypeError: Cannot read property 'data' of undefined [http://localhost/x/Scripts/kendo.web.min.js:13]
Here's the grid:
function directorsOrRecipients(e)
{
awardTitleId = e.data.AwardTitleId;
var detailRow = e.detailRow;
detailRow.find(".childTabstrip").kendoTabStrip({
animation: {
open: { effects: "fadeIn" }
}
});
detailRow.find(".directorsOrRecipients").kendoGrid({
reorderable: true,
resizable: true,
dataSource: {
transport: {
read: {
url: "http://localhost/x/api/Awards/directors/" + awardTitleId,
type: "GET"
},

"isonballot": { editable: true, type: "string" },
"concatenation": { editable: true, type: "string" },
"MoreNames": { editable: true, type: "number", validation: { min: 0 } },
}
}
}
},

{ field: "concatenation", title: "Concatenation" },
{ field: "MoreNames", title: "More names?", format: "{0:n0}" },
{ command: ["edit"], title: " ", width: 100 }],
sortable: true,
sort: { field: "namefirstlast", dir: "desc" },
editable: "inline",
toolbar: [{ name: "create", text: "Add New Director/Recipient" }],
save: function(e)
{
debugger;
if (e.data != "undefined")
{
$.ajax({
url: "http://localhost/x/api/awards/directors",
type: "POST",
dataType: "json",
data: $.parseJSON(directorData)
}).done(function()
{
alert('done!');
});
}
}
});
function onBallotDropDownEditor(container, options)
{
var data = [
{ "onBallotId": 1, "onBallotDescription": "Yes" },
{ "onBallotId": 2, "onBallotDescription": "No" }];
$('<input required data-text-field="onBallotDescription" data-value-field="onBallotDescription" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
autoBind: false,
dataSource: data
});
}
}
After Success in Ajax call try this,
$('#GridName').data('kendoGrid').dataSource.read();
$('#GridName').data('kendoGrid').refresh();
In controller update function return an object insted of empty Json, like this it worked for me
return Json(ModelState.IsValid ? new object() : ModelState.ToDataSourceResult());
I'm working on kendoui. If we observe a grid then all the values are on the left side of each cell.I have a field of price and i want its value on the right side of cell.
Is it possible in kendo ui?

You can use a column template to wrap the contents of all the cells in that column in for example a div-tag.
You can then use a class on the div to style the contents using CSS.
For example:
columns:
[{
field:"Department",
title:"Department",
width:80,
template: "<div class='foobar'>#= Department#</div>"
}]
/* CSS */
.foobar {
width: 100%;
text-align: right;
}
