Hello,

I would like to make a general feedback after visiting KendoReact website for the first time. I'll expose a lot of wrongs, but keep in mind my goal is to give you insight for improvement, not to bash.

Context : I'm currently curating React UI frameworks for a new long term project within my company. I am a senior software architect seeking some general feelings about a the product (reliability and performance for example) but also very specific : easy layout management and very accomplished components such as Select.

 

Navigation

The documentation website ( https://www.telerik.com/kendo-react-ui/components ) is extraordinarily slow, this is very inconvenient when you're browsing to discover what the kit has to offer.

Accessing sub-section actually change the page, requiring a full reload, which again, is so slow I don't want to click on it. Seriously.
Take https://www.telerik.com/kendo-react-ui/components/dropdowns/multiselect/ for example, to discover all the features, I have to trigger several page load. This is not gonna happen ; I'll leave this. I did leave this. It's the most wanted component for me in my research. I left.

Content

The documentation pages does not expose the available properties of the component, I have to visit every sublink and read every source to find out. This is not ok either. I'm looking for a framework to save time, and this is starting to seriously leech my time.

The source code of the given examples are real. I can copy paste into an empty file, and it will work. This is the good side of the coin. The bad side of the coin is it takes me an, abnormal amount of time to see how the component is structured. That's the only thing that interest me on the first look. If I want deeper understanding and knowledge, yes please provide with a link to stackblitz or whatever so I can play with it, but first I want to see what it looks like.

You use unconventional naming. Look around in the js world, how people call stuff :

A form select is a select, not a dropdown. Within your dropdown menu item you have multi-select but you have to find it first !
A grid is a css grid, not a DataTable.
You have in your menu : Forms, Dropdown Select, Inputs, Upload. All of that is Form. How am I supposed to know if I've seen all form features if everything is spread around ? You also have Chart, Gauge and Drawing.
PanelBar ? Never heard of it. Accordion ? That's my boy.

You also present features that don't belong here, like Excel Export or PDF Processing whereas some basic information are missing such as "does it work well with TypeScript ?" : https://www.telerik.com/kendo-react-ui/knowledge-base/?search=typescript .

 

Features

You have a lot of components, some are very accomplished (i.e. TreeList) and others are quite average, such as Select. Check this competitor component : https://blueprintjs.com/docs/#select. Real world usages. Maybe you can achieve the very same thing with KendoReact, but even if true, I feel you don't understand what I need.

Too few UI framework care about layouts, KendoReact unfortunately is no exception. Layout is not just a box next to another. Layout is ordering content and filtering content depending on the device, it's putting some text over an image, it's making a row of three blocks and make sure they have the same height regardless of their content, it's having a page section that is exactly the size of the visitor's screen ; UIKit is very good at this ( https://getuikit.com/docs/height ). But it's also Special States : empty state ( https://material.io/design/communication/empty-states.html#content ) or result state ( https://ant.design/components/result/ )

 

My overall feeling is the product is disconnected from the environment and dev culture I'm working in.

Hello, 

I would like to request for the filter component to be supported in the KendoReact suite as it is in the ASP.NET Core UI suite.

One aspect is the hierarchical structure which can support complex filter scenarios but also the support to persist state of a set of filters.

Thank you

In the case of multiple columns headers, the column width of the KendoReact  TreeList  is invalid

 

 

When can I release the Spreadsheet in Kendo UI for React,not Wrapper

Is there any prop so that I can trigger another event on press of cancel button on KendoCalender.

Add render prop for the SplitButton.

This will allow changing the main button and also the button that opens the DropDownList.

 

Q:

From the last conversation through the webinar

jQuery Filter looks cool! What about Kendo React Filter?

I'd really like a KeepIt prop on https://www.telerik.com/kendo-react-ui/components/conversationalui/api/Action/ so that the action stays even when someone is typing or there is another message below it.

The use case would be a link to a Order # for example that they could go back to and click.

Example of how this works with react-native-gifted-chat:

Hello,

 

We need to create a DateTime Picker with max and min limit on Date and also Time.

Currently, the range works as of 22/09/2019 5:30 AM to 21/09/2020 5:30 PM, where complete 24 hrs is been selectable.

We need the time range to be restricted per day. For instance, in the above example, it should be 5:30 AM to 5:30 PM per day from 22/09/2019 till 22/09/2020.

 

Thanks in advance.

Create a function callback for the Upload saveUrl.
This will allow for more flexibility when making requests.

Column locked with KendoReact Grid is not locked in the iPhone safari.  It's OK in Chrome phone simulator, but not in mobile. 

 

<Grid
                    style={{ height: '400px', width: '500px' }}
                    data={products}
                    reorderable
                >
                    <Column field="ProductID" title="ID" width="45px" locked />
                    <Column field="ProductName" title="Name" width="250px" />
                    <Column field="Category.CategoryName" title="CategoryName" />
                    <Column field="UnitPrice" title="Price" width="90px" />
                    <Column field="UnitsInStock" title="In stock" width="90px" />
                    <Column field="UnitsOnOrder" title="On order" width="90px" />
                    <Column field="Discontinued" width="120px" locked={true} />
                    <Column field="QuantityPerUnit" title="Additional details" width="250px" />
                </Grid>

Please add toolbar support in the react conversationalui, just like it exists in the jQuery chat component.

We need in our projects a way to add custom action buttons, besides the simple "send" message.

Ie. attach files/images to a message, open emoji picker, etc.

Hello, 

I would like to request the support of the search panel within the grid component same as in ASP.NET Core UI (https://demos.telerik.com/aspnet-core/grid/search-panel)

Thank you

Hi

Please create a React Scheduler component similar to https://demos.telerik.com/aspnet-ajax/scheduler/examples/overview/defaultcs.aspx

in 0.3.0 release I was able to describe a column by percentages.  i.e.

<Column field="certification" title="Certification" width="40%" />

This no longer works in the 1.0.1 release

Add support for styled components.

This will allow lazy loading for the styles depending on the used features of a component to reduce the styles sheet size.

KendoReact Editor not working in NextJS application.

This is the error:

ReferenceError: navigator is not defined.

The error can be reproduced in our NextJS application as well when adding the Editor component.

The error may occur due to this line:

const firefox = /Firefox/.test(navigator.userAgent);

In Panelbar , when we set expandmode set to 'single' it do not toggle the item . it only works with expandmode 'multiple'. 

We should also allow to toggle a panelbar item in 'single' mode 
a use case could be -i want to close all of the items in single mode

Hi, I'm trying to know if the components that are publicly exposed do not contain the correct styles. For example I tried to do this: 'https://www.telerik.com/kendo-react-ui/components/grid/editing/editing-all-cell/' but the result is not even close to what it should look like and I want know if it is because these styles / features are only with the paid version.
