I would like there to be a simple input field that allows a datasource to be attached. This would support update database operations to be sent as JSON to the desired URL, much like grid or gantt do.
Seems a bit of an oversite that you don't have this on, given the width and breadth of your other controls.
1)I have configured drop-down(list) for the values in the cell of spread sheet.
2)Scroll bar is not coming in that drop down list.
3)Due to which if list is big ,it is going out of sheet.
4)Please see the screenshot attached to see the issue.
5)Kindly reply.
1. Please add zooming functionality to pdf viewer, so user can zoom in or zoom out
2. please allow us to hide toolbar buttons
Kendo UI mobile widgets are really falling behind and now need an urgent refresh. Most mobile widgets have not been updated in 3 to 4 years (https://github.com/telerik/kendo-ui-core/tree/master/src).
The most urgent is for styles to be updated to match LESS and SASS styles. Currently, styles are a mess and making a mobile app including the grid and other recent responsive widgets with consistent styles takes a lot more time than it should:
- NOVA has many specificities not available in other themes
- OS skins have no match to style the grid and other web responsive widgets
- Material UI is not consistent and up-to-date
Bug report
An error occurs on components' initialization when using a custom Kendo UI build which includes PDFviewer
Reproduction of the problem
- Go to Kendo UI Custom Download page
- In the "WEB" section select random components including the Grid and PDFviewer
- Download the custom build(kendo.custom.min.js file) and put it in the same folder with an HTML file with the following structure.
<!DOCTYPE html>
<html>
<head>
<style>
html {
font-size: 14px;
font-family: Arial, Helvetica, sans-serif;
}
</style>
<title></title>
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.2.514/styles/kendo.default-v2.min.css" />
<script src="https://kendo.cdn.telerik.com/2019.2.514/js/jquery.min.js"></script>
<script src="./kendo.custom.min.js"></script>
</head>
<body>
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function () {
$("#grid").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
},
pageSize: 20
},
height: 550,
groupable: true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [{
template: "<div class='customer-name'>#: ContactName #</div>",
field: "ContactName",
title: "Contact Name",
width: 240
}, {
field: "ContactTitle",
title: "Contact Title"
}, {
field: "CompanyName",
title: "Company Name"
}, {
field: "Country",
width: 150
}]
});
});
</script>
</div>
</body>
</html>- The following error appears:
Uncaught TypeError: Cannot read property 'Toolbar' of undefined
Current behavior
Expected/desired behavior
A Grid should be initialized properly and without errors if a custom build is including the PDFviewer

Does Kendo.Ooxml.Workbook have a setter for which sheet opens after the workbook is saved as an excel, similar to activeSheet in Kendo.spreadsheet?
(Note: using Kendo MVC ver 2017.3.913.545 - it's not on the list below)
Dear Telerik,
Please check this example. The single difference than the original one from the demos section, is that I deleted the tasksDataSource.schema.model.fields.parentId.defaultValue". Now the default value of the parentId will be 0 instead of null. If you try to add a new task, the logic will break because of inifinity loop caused by the new task with id=0 and parent=the same task(parentId=0).
I checked the documentation at https://docs.telerik.com/kendo-ui/api/javascript/data/ganttdatasource/configuration/schema and this obligation is missing. It is something small that can save an hour to someone else.
Best Regards, Boyan.
If the delete rows button is used on a table that is followed by another table, and all the rows from the first one are deleted, the next table receives focus. Upon clicking the delete row button again, an error is being thrown "Cannot read property 'rows' of undefined".
The issue can be reproduced with the Basic Usage Demo::
- create a table
- create a table immediately following the first
- focus the last row of the first table and click the 'Delete row' button until all rows are deleted.
- Click the 'Delete row' button again.

Saving large data to xlsx takes longer time to complete.
Evaluate optimizing the value setting and the usage of CellSelection.

open new window using the button, and close all window one by one, then see that k-overlay is still stay in page
In the Wizard to create or update an MVC project, and possibly other wizards, please add support for choosing which cultures that you want to include.
This could be done by adding checkboxes in a tree where you could at first level choose language and then expand and choose country/region, since the files follow the format:
<language code>-<country/region code>.
Most people probably only use English and/or their native language, so please make this a choice in the wizard.
As an example. In one of the latest versions of the framework, the folders for cultures and messages contain 1786 files in total. Out of those we only need 2, the ones for our native language.
Slowly installing and then manually deleting 1784 files in Visual Studio for every time you run the MVC wizards, is a complete waste of time for such a common scenario where you know whihc languages that the app should support.
Binding the map layers to a SignalR Core datasource does not work. A runable project can be found in Ticket ID: 1401776
The basic configuration is:
<script>
var hub = new signalR.HubConnectionBuilder().withUrl("mapsHub", { transport: signalR.HttpTransportType.LongPolling }).build();
var hubStart = hub.start();
console.log(hubStart);
</script>
@(Html.Kendo().Map()
.Name("map")
.Center(2, 21)
.Zoom(3)
.Layers(layers =>
{
layers.Add()
.Type(MapLayerType.Tile)
.UrlTemplate("http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png")
.Subdomains("a", "b", "c");
layers.Add()
.Type(MapLayerType.Marker)
.DataSource(dataSource => dataSource
.SignalR()
.AutoSync(true)
.Transport(tr => tr
.Promise(handler: "hubStart")
.Hub("hub")
.Client(c => c
.Read("senddata")
)
.Server(s => s
.Read("senddata")
)
)
);
})
.Markers(markers =>
{
})
.Events(events => events
.MarkerClick("onMarkerClick").MarkerCreated("onMarkerActive"))
.Deferred()
)

1. Navigate to: https://dojo.telerik.com/@milena/uZaGuZol (open the dojo sample in edit mode, but not in FullScreen)
2. Scroll Grid to the last item.
3. Open for editing ProductName cell.
4. Open for editing Discontinued cell.
Result: 'Discontinued' cell of the second item will be opened for editing.
Expected: 'Discontinued' cell of the last item should be opened for editing.
Bug report
When the filtering mode of the grid is set to "row" and the filter is programmatically cleared, the "Clear filter" button does not hide.
Reproduction of the problem
Set filterable: {mode: "row"}.
Filter for instance "Is null" or "Is not null".
Clear the filter - $("#grid").getKendoGrid().dataSource.filter({});
The "Clear filter" button is not hidden
sample Dojo:
https://dojo.telerik.com/AVOqifeK
If there is text in the filter's input, the button is hidden.
Expected/desired behavior
Hide the "Clear filter" button, irrespectively whether the filter has been cleared programmatically or via the UI.

Hi,
FluentValidation is an excellent tool that keep us from using DataAnnotations' Validator's decorators to achieve the entity class keeps as is, a just POCO class. The pros of this lead us to those developers, like me, that focus its backend (entities) development in Database-First processes, to lose decorators applied to the entity or model view class in every change made to the Database rather than the entity class, FluentValidation give us a better control of the validation rules, separates the validation from the entity class or view model class, testing is easier than DataAnnotations and support client-side validations. As far as I know, FluentValidation injects Data Annotation under the covers.
It would be great if you consider to take advantage of the integration with this tool in your route map.
Thanks
