Kendo dataviz pie chart as button - kendo-ui

Is it possible to use the Kendo-Dataviz pie chart as a button control. I want every piece to be a different control.
I could not find anything like that in the documentation.

You might define a seriesClick event. Something like:
$("#chart").kendoChart({
series: [
{
type: "pie",
categoryField: "type",
data: [
{ value: 1, type: "Category 1" },
{ value: 2, type: "Category 2" }
]
}
],
seriesClick : function (e) {
alert("You clicked on: " + JSON.stringify(e.dataItem));
}
});
See it running here : http://jsfiddle.net/rS3T4/

KendoUI Multiselect deselect event is not binded properly in jquery

I tried to bind the 'deselect' event to the KendoUI multiselect control using jquery. But seems like it is not firing: Here is the code:
$(document).ready(function () {
function multiselect_deselect(e) {
debugger;
if (e.item.context.localName == 'li') {
e.preventDefault();
}
}
var multiselectCtrl = $("#enterFeedbackForm_" + '#ContextId' + " #FeedbackCategoryList_" + '#ContextId').data("kendoMultiSelect");
multiselectCtrl.bind("deselect", multiselect_deselect);
});
the debugger point does not hit. We're using Kendo UI Kendo UI v2015.2.703
I think kendo-ui has a bound property for this already. If you take a look at the event documentation, it shows you how to bind the events on initialization of kendo ui multiselect:
$(document).ready(function() {
function onDeselect(e) {
debugger;
if (e.item.context.localName == 'li') {
e.preventDefault();
}
};
var data = [
{ text: "Africa", value:"1" },
{ text: "Europe", value:"2" },
{ text: "Asia", value:"3" },
{ text: "North America", value:"4" },
{ text: "South America", value:"5" },
{ text: "Antarctica", value:"6" },
{ text: "Australia", value:"7" }
];
$("#select").kendoMultiSelect({
dataTextField: "text",
dataValueField: "value",
dataSource: data,
deselect: onDeselect,
});
});

How to use more than one button in one field in Kendo Treelist?

I want to use 2 or more buttons in one field like Kendo Grid by using custom command in TreeList but I could not do that. Does anyone have a solution?
You just add an array of buttons to the column command property:
$("#treeList").kendoTreeList({
columns: [
{ field: "name" },
{
command: [
{
name: "Cust1",
text: "Custom1",
click: function(e) {
alert("Custom1");
}
},
{
name: "Cust2",
text: "Custom2",
click: function(e) {
alert("Custom2");
}
},
]
}
],
editable: true,
dataSource: dataSource
});

Making a Kendo Grid link template behave like a command

I have a Kendo Grid, and instead of having a custom command:
$('#grid').kendoGrid({
dataSource: data,
columns:
[
...
{ command: { text: "Details", click: showDetails }, title: " " }
]
});
I'd like the same behavior to occur but on a standard link. Is it possible?
This is the functionality I'm looking for: http://jsfiddle.net/dmathisen/ERgkA/2/
But want it to behave like this: http://jsfiddle.net/dmathisen/qXAf6/4/
This is similar to what I use in my own projects. You can use whatever markup you desire and style it however you want to make it look functional.
function showDetails(e) {
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
document.getElementById('details').innerHTML = dataItem.quantity;
}
var data = [
{ name: "name1", quantity: 1 },
{ name: "name2", quantity: 4 },
{ name: "name3", quantity: 9 }
];
var grid = $('#grid').kendoGrid({
dataSource: data,
columns: [
{ field: 'name', template: '#= name #' },
{ field: 'quantity' }
]
}).data('kendoGrid');
grid.table.on('click', '.link', function(e) {
showDetails.call(grid, e);
});

Kendo line chart notes aren't shown

I use kendo dataviz chart and want to add notes. This is the code I've written
$("#resultChart").kendoChart({
dataSource: resultsDataSource,
title: {
text: "Results"
},
legend: {
position: "bottom"
},
chartArea: {
background: ""
},
seriesDefaults: {
type: "line"
},
series: [{
field: "Points",
name: "Points",
noteTextField: "EventName",
notes: {
label: {
position: "outside"
},
position: "bottom"
}
}],
valueAxis: {
labels: {
format: "{0}"
},
line: {
visible: false
},
axisCrossingValue: -10
},
categoryAxis: {
field: "EventDate",
majorGridLines: {
visible: false
}
},
tooltip: {
visible: true,
format: "{0}%",
template: "#= series.name #: #= value #"
}
});
Everything is working as needed, i.e. chart is drawn with appropriate data, but notes aren't shown.
Please help me find out why notes aren't shown, if there's data in "EventName" property(I've checked). I want to mention that I am using kendo ui 2013.1.514 version.
Thank you in advance.
In your series definition, you have noteTextField: "EventName", which means you must have the property EventName defined for each item in your DataSource, as #ccsakuweb alluded to.
This means that in your DataSource, the data items should look something like this:
var data = [
{ Id: 1, Name: "Result #1", EventName: "Note 1" },
{ Id: 2, Name: "Result #2", EventName: "Note 2" }
];
Kendo's documentation about the Notes feature is located at http://docs.telerik.com/kendo-ui/dataviz/chart/notes .

Kendo Grid handling create/delete errors with popup editor

I have a kendo grid that does a create/delete, both of them ending with errors.
I would like to:.
When having an error on delete to prevent the row deleting from the grid (that is the default behavior when having errors)
When having a create error to prevent the popup editor to close
Please see this fiddle:
http://jsfiddle.net/andreigavrila/p49eV/2/
var data = [
{ Id: 1, Name: "Decision 1", Code: 1 },
{ Id: 2, Name: "Decision 2", Code: 2 },
{ Id: 3, Name: "Decision 3", Code: 3 }
];
$("#grid").kendoGrid({
dataSource: {
error: function (a) {
console.log('error');
$('#grid').data("kendoGrid").cancelChanges();
//$('#grid').data("kendoGrid").one("dataBinding", function (e) {
//e.preventDefault(); // cancel grid rebind
//});
},
transport: {
read: function(e) {
e.success({data: data});
},
create: function(e) {
console.log('creating');
e.error();
},
destroy: function(e) {
console.log('deleting')
e.error();
}
},
schema: {
data: "data",
model: {
id: "Id",
fields: {
Id: { type: "number" },
Code: { type: "number" },
Name: { type: "string" }
}
}
}
},
toolbar: ["create"],
columns: [
{ field: "Code", title: "Code", },
{ field: "Name", title: "Name" },
{ command: ["destroy"], title: " " }],
editable: {
mode: "popup"
}
});
The second point works by default (so having an error on create does not close the popup)
The first point works by adding the error function, but that breaks the popup (it closes on error).
So I can have either one of my , but not both in the same time. I am kind of stuck.
I also saw this 2 questions on kendo forums:
delete error
server validation
The second link said "to prevent the Grid from closing you need to prevent the next dataBinding event." but i can't make that work.
Thank you for your help.
Andrei
I finally managed to push this to Kendo forums:
Tthe official solution to that:
http://www.kendoui.com/forums/kendo-ui-web/grid/kendo-grid-handling-create-delete-errors-with-popup-editor.aspx
"I suggest you to use an if condition in the error event handler to
determine which of the two workarounds should be executed. In this
case the server should provide information about type of the error
that occurred. You can retrieve the error status from error event
arguments."
