I try to add a button to the last column of my Gridx, however, the button is not shown and above the other table data the grid just says "loading...".
Cell Widget is required and declared, widgetInCell is set and onCellWidgetCreated function added. When replacing the onCellWidgetCreated function with alert, an alert message for each row is shown and the "loading..." disappears. My feeling is that the onCellWidgetCreated function is wrong?
My code looks like the following and when comparing it against some examples on the Gridx website I cannot find the problem.
require([
"gridx/Grid",
"gridx/core/model/cache/Sync",
"dojo/store/Memory",
"dojo/domReady!",
"gridx/modules/CellWidget",
"dijit/form/Button"
], function(Grid, Cache, Memory,Button,CellWidget,domConstruct){
var store = new Memory({
idProperty:"CategoryID",
data: jsondata
});
var grid = new Grid({
id:"gridId",
store: store,
cacheClass: Cache,
structure: [
{
id: "0",
field: "CategoryID",
name: "Kategorie (ID)",
width: "100px"
},
{
id: "1",
field: "CategoryName",
name: "Kategoriename"
},
{
id: "2",
field: "Attributes",
name: "Attribute"
},
{
id: "3",
field: "Actions",
name: "Aktion",
widgetsInCell: true,
onCellWidgetCreated: function(cellWidget, column){
var btn = new Button({
label: "Click me!"
});
btn.placeAt(cellWidget.domNode);
}
}
],
modules: [
CellWidget
]
});
grid.placeAt("aGrid");
grid.startup();
}
);
I came across anotheer problem with VirtualVScrolling and found out that this was due to a defective gridx css file which contained a custom layout.
When using the standard css file, "onCellWidgetCreated" worked for me as well.

Is it possible to get the selected items count in the kendoMultiSelect's footerTemplate?
I created a DOJO example with an attemp to use instance.dataItems().length but for some reason, the value is always 0.
$("#customers").kendoMultiSelect({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }
],
dataTextField: "name",
dataValueField: "id",
footerTemplate: '#: instance.dataItems().length # item(s) selected'
});
EDIT:
due #Aleksandar comment where he points out
Calling setOptions in an event handler or the respective widget is not
recommended and can cause an endless loop or a JavaScript error.
I take his suggestion into account and add his solution as an answer.
footerTemplate: '<span id="total">#:instance.value().length#</span> item(s) selected',
change:function(e){
var itmsSelected = e.sender.value().length;
$("#total").html(itmsSelected);
}
OBSOLETE:
Guess it's not in an observable object. One of the possible solutions is to change footerTemplate
every time a change happens on multiSelect:
var multi = $("#customers").kendoMultiSelect({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }
],
change: function() {
this.setOptions({"footerTemplate": this.value().length +" item(s) selected"});
},
dataTextField: "name",
dataValueField: "id",
footerTemplate: '0 item(s) selected'
}).getKendoMultiSelect();

Following the example here, we've been trying for over a week to get Tabulator working with a Select2 header filter. There is a JS Fiddle here with all the pieces. It seems like the Tabulator filter (which are really just editors) onRendered() function is not even getting called because the console log we have inside it never gets logged.
The select element itself shows up in the header filter, but never gets the Select2 object applied (probably because the onRendered seems to not even be called). If we put the Select2 object outside the onRendered function, it get applied, but then the filter does not get applied after selection is made. There are no console or other errors and we've followed the Tabulator 'example' to the letter, so we are not sure what to try next.
Does anyone know how to get a basic Select2 header filter functioning with Tabulator?
var tableData = [{
id: "1",
topic: "1.1"
},
{
id: "2",
topic: "2.2"
},
];
var select2Editor = function(cell, onRendered, success, cancel, editorParams) {
var editor = document.createElement("select");
var selData = [{
id: '1.1',
text: "One"
}, {
id: "2.2",
text: "Two"
}, {
id: "3.3",
text: "Three"
}, ];
onRendered(function() {
// TODO: map tracks to id and text
console.log('rendered');
$(editor).select2({
data: selData,
minimumResultsForSearch: Infinity,
width: '100%',
minimumInputLength: 0,
//allowClear: true,
});
$(editor).on('change', function(e) {
success($(editor).val());
});
$(editor).on('blur', function(e) {
cancel();
});
});
return editor
};
var columns = [{
title: "ID",
field: "id"
}, {
title: "Topic",
field: "topic",
headerFilter: select2Editor,
}, ];
var table = new Tabulator("#table", {
placeholder: "No Data Found.",
layout: "fitData",
data: tableData,
columns: columns,
});
I'm new to both Tabulator and select2 and I think this is possibly a bad way to do it but it seems like it miiight work.
If you want to use select2 with text input elements, it looks like you need to use the full package.
https://jsfiddle.net/dku41pjy/
var tableData = [{
id: "1",
topic: "1.1"
},
{
id: "2",
topic: "2.2"
},
];
var columns = [{
title: "ID",
field: "id"
}, {
title: "Topic",
field: "topic",
headerFilter: 'select2Editor'
}, ];
var awaiting_render = [];
function do_render({ editor, cell, success, cancel, editorParams }) {
console.log('possibly dodgy onrender');
var selData = [{
id: '',
text: "-- All Topics --"
}, {
id: '1.1',
text: "One"
}, {
id: "2.2",
text: "Two"
}, {
id: "3.3",
text: "Three"
}, ];
$(editor).select2({
data: selData,
//allowClear: true,
});
$(editor).on('change', function(e) {
console.log('chaaaange')
success($(editor).val());
});
$(editor).on('blur', function(e) {
cancel();
});
}
function render_awaiting() {
var to_render = awaiting_render.shift();
do_render(to_render);
if(awaiting_render.length > 0)
render_awaiting();
}
Tabulator.prototype.extendModule("edit", "editors", {
select2Editor:function(cell, onRendered, success, cancel, editorParams) {
console.log(cell);
var editor = document.createElement("input");
editor.type = 'text';
awaiting_render.push({ editor, cell, success, cancel, editorParams });
return editor
},
});
var table = new Tabulator("#table", {
placeholder: "No Data Found.",
layout: "fitData",
data: tableData,
columns: columns,
tableBuilt:function(){
render_awaiting();
},
});
Edit: my suspicion is that onRendered only gets fired when these edit elements are used in cells to sope with the transition between showing just data and showing an editable field.
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
I'm evaluating the Kendo UI Gantt chart to see if it fits our project requirements.
One particular requirement is to display a status column which would be a drop down in edit mode and has three statuses
Red 2. Green 3. Yellow, along with an image indicator something like what is shown in the image below
I am able to achieve the above effect when i edit a cell after using a custom editor for the drop down
function statusDropDownEditor(container, options) {
$('<input data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
dataTextField: "Status",
dataValueField: "StatusId",
valueTemplate: '<img class="selected-value" src="#:data.Url#" alt="#:data.Status#" /><span>#:data.Status#</span>',
template: '<img class="selected-value" src="#:data.Url#" alt="#:data.Status#" /><span>#:data.Status#</span>',
dataSource: {
transport: {
read: function (e) {
// on success
e.success([{ Status: 'Not Started', StatusId: '0', Url: 'Image/red.png' }, { Status: 'Red', StatusId: '1', Url: 'Image/red.png' }, { Status: 'Green', StatusId: '2', Url: 'Image/red.png' }, { Status: 'Yellow', StatusId: '3', Url: 'Image/red.png' }]);
// on failure
//e.error("XHR response", "status code", "error message");
}
}
}
})
}
The Gantt Column for Status looks like the below snippet
{ field: "status", title: "Status", editable: true, width: 150, editor: statusDropDownEditor, template: '<img class="selected-value" src="#:data.Url#" alt="#:data.Status#" /><span>#:data.Status#</span>' }
However when done with selecting a particular item from drop down and on exiting the edit mode this is how the cell looks like
Seems like the default cell template in read only mode does not render html and the invokes the toString of the object bound to the cell, is there a way to fix this in the kendo UI Gantt
I have been trying to solve the same issue today and it looks like gantt columns do not support the template properties.
I have created a new feature suggestion on the Kendo user feedback site. If enough people vote for it maybe they will implement this.
The only work around I found was to prepend an image tag onto the field column like this. But this solution is not conditional.
<div id="gantt"></div>
<script>
$(document).ready(function() {
var gantt = $("#gantt").kendoGantt({
dataSource: [
{
id: 1,
title: "apples",
orderId: 0,
parentId: null,
start: new Date("2015/1/17"),
end: new Date("2015/10/17"),
summary:false,
expanded:false
},
{
id: 2,
orderId: 1,
parentId: null,
title: "banana",
start: new Date("2015/1/17"),
end: new Date("2015/3/17"),
summary:false,
expanded:true
}
],
views: [
{ type: "year", selected: true }
],
columns: [
{ field: "title", title: "fruit", width: 220 },
{ field: "start", title: "start", width: 80 }
],
}).data("kendoGantt");
$(".k-grid-content tbody[role='rowgroup'] tr[role='row'] td:first-child").prepend("<img href='#' alt='image here'></img>");
});
</script>

I am using Dojo Dgrid however i am trying to add a checkbox column however i am not sure of the approach.
Most of the tutorials i have been looking at follow a different code structure and i am unable to create the check box column. I would like to create a checkbox column to select rows
Code (Here is also a Fiddle of my code)
require([
.......................
"dojo/domReady!"
], function(parser, declare, Grid, ColumnSet, Selection, selector,Keyboard, DijitRegistry){
parser.parse();
var data = [
{ first: "Tom", last: "Evans" },
{ first: "Sherry", last: "Young"},
{ first: "Bob", last: "William"}
];
var columns = [
[[
{editor({name: "CheckBox", field: "bool"}, "checkbox")},
{ field: "first", label: "First" },
{ field: "last", label: "Last" }]]
];
var CustomGrid = declare([Grid, ColumnSet, Selection, Keyboard, DijitRegistry]);
var grid = new CustomGrid ({
columnSets: columns ,
"class":"grid"
}, "grid");
grid.renderArray(data);
});
If you want to have a column with checkboxes for the purpose of selecting rows, you should set your sights on the selector column plugin rather than editor. selector is specifically designed to render checkboxes (or radio buttons) in each cell that ties in to the Selection mixin when checked.
See the documentation in the wiki, and the selector test page.
you can also test this solution
first you must add this Modules in require([]) section
"dgrid/extensions/ColumnResizer",
"esri/request", "dgrid/OnDemandGrid", "dgrid/Selection", "dojo/store/Memory", "dgrid/selector",
then define this array to hold your columns
var columnsPol = [];
then add check box type column to array and any other type column to array
columnsPol.push(
selector({ label: selector({}), selectorType: "checkbox" })
);
columnsPol.push({
label: "",
field: {any name},
formatter: {a function for formatting value of cell},
width: "auto",
});
.
.
.
then define your Grid and set properties
var gridPol = new (declare([Grid, ColumnResizer, Selection]))({
store: {your data},
columns: columnsPol,
minRowsPerPage: 40,
maxRowsPerPage: 40,
keepScrollPosition: true,
selectionMode: 'none',
allowSelectAll: true,
loadingMessage: "Loading data...",
noDataMessage: "No results found."
}, {Id for grid});
gridPol.refresh();
and then you can get selected and deselected rows
gridPol.on("dgrid-select", function (event) {
var selectedRows = event.rows;
});
and deselect
gridPol.on.on("dgrid-deselect",function (event){
var deselectedRows = event.rows;
});
