I know that Kendo React components could loaded only with script files but I want maintain the TypeScript standard. So, it is not possible.

I have attached the simple example application. Please help me to clear this. I have gone through multiple resource but not able to get it worked with Kendo component. Without Kendo there is no issue.

Style the tooltip

Hi everybody

I was wondering how to style the tooltip, preferrably with styled components. It should have a white background and black font color. The text should spread over 3 lines and the tooltip should have a drop shadow.

But this looks not at all what I expect.

const StyledTooltip = styled(Tooltip)`

background: white;

color: black;

height: 116px;

`;

I don't need a full solution, but a hint, how to style the tooltip.

Thanks in advance

Lukas

Add KendoReact to Externals to reduce packaging

Hi,

I'm trying to figure out how to package my solution based on the "Create-React-App" template (TypeScript). I want to use the Externals node in the webpack configuration to ensure the KendoReact packages are excluded from the packaging procedures.

I saw this article: https://www.telerik.com/kendo-react-ui/components/installation/scripts-only . However, this approach means i need to reference all controls via the Window object. I rather keep the code base as is, so using import statements like

import { Grid, GridColumn as Column } from "@progress/kendo-react-grid

and use the control in Jsx. Is this possible?

Best regards,

Ruud

Kendo React Grid, build programmatically

Does anyone know where I could find an example of a Kendo React Grid that is databound programmatically to an API Endpoint data source.

The paging would be done by passing a page number to the Endpoint.

I have no idea how to sort or filter the entire dataset if the grid is only showing a subset (page) of the data.

Functional Component example for KendoReactGrid

Hi, I'm currently working on react functional component using Kendo React Grid. But, Couldn't process (using process from kendo-data-query)

data using functional state variable. Could you please provide a Kendo React Grid functional component (using useState, useEffect..) example?

Below is code i'm working on:

import React, { useEffect, useState } from "react";

import { getAllFmsForms } from "../../apis/fmsFormApi";

import { Grid, GridColumn } from "@progress/kendo-react-grid";

import { process } from "@progress/kendo-data-query";

import "@progress/kendo-theme-bootstrap/dist/all.css";

const Forms = () => {

const [formsList, setFormsList] = useState([]);

const dataStateObj = {

skip: 0,

take: 20,

sort: [{ field: "formNumber", dir: "desc" }],

group: [{ field: "formNumber" }],

};

useEffect(() => {

const getAllForms = async () => {

try {

const response = await getAllFmsForms();

setFormsList(response);

} catch (error) {

console.log("error in getAllForms ===> ", error);

};

getAllForms();

}, []);

return (

<>

<h3>List</h3>

<Grid

sortable

filterable

pageable={{ buttonCount: 4, pageSizes: true }}

data={process(formsList,dataState)} ---> error

onDataStateChange={(e) => {}}

>

<GridColumn field="formNumber" title="Form Number" />

<GridColumn field="formTitle" title="Form Title" />

<GridColumn

field="revisionDate"

title="Revision Date"

/>

<GridColumn field="formStatus" title="Form Status" />

<GridColumn field="responsibleOffice" title="Office" />

</Grid>

</>

);

};

export default Forms;

I've tried below way too:

const [dataState, setDataState] = useState({ dataResult: process(formsList, dataStateObj), ----> error with dataStateObj dataState: dataStateObj, });

How to rerender master grid when i click in button from the detail grid ?

Hello,

https://imgur.com/a/1zohd9u

I ask how to rerender master grid when i click in button from the detail grid (look the picture).

Once i click in Rejected/Accepted button in detail grid, the database will be updated and the statut field of master grid change (in database).

but the new value not displayed because i have to manually refresh the page.

I need to setState the data of the master grid to refresh it and display the updated value of Statut field knowing that the button is in detail grid, so how to get access to function that update the state of master grid data ?

Thank you

Pass custom props to Grid

Hello.

We are testing with selenium and jest and the pattern we use to identify elements is through the use of data-* attributes. We are trying to follow this same pattern with the Kendo React components but, at least for the Grid component so far, any custom props that we pass in are ignored by the component. From a design pattern perspective I totally understand why this would happen but I am wondering if there is some way to achieve what is described below:

React Component

Rendered Output

...data...

</div>

Reading through the API documentation I couldn't seem to find anything.

Thanks!

Tooltip not working for me

01.

<Tooltip openDelay={100} position="right" anchorElement="element">

02.<Grid

03. data={process(this.state.managers.map((manager) => ({...manager, selected: manager["mail"] == this.state.selectedID}) ), this.state.gridDataState)}

04. {...this.state.gridDataState}

05. onDataStateChange={this.handleGridDataStateChange}

06. style={{ height: "300px" }}

07. pageable={true}

08. sortable={true}

09. selectedField="selected"

10. onRowClick={(e) => {

11. this.setState({ selectedID: e.dataItem.mail });

12. this.props.callback(e.dataItem.mail);

13. }}

14.>

15.

16. <Column field="mail" title="email" filter={'text'} headerCell={MailHeader} columnMenu={ColumnMenu} headerClassName="k-header-filtered" />

17. <Column field="givenName" title=”first name” filter={'text'} columnMenu={ColumnMenu} headerClassName="k-header-filtered" />

18. <Column field="sn" title=”last name” filter={'text'} columnMenu={ColumnMenu} headerClassName"k-header-filtered”/>

19. <Column field="managerOf" title=”manager of” filter={'text'} columnMenu={ColumnMenu} headerClassName="k-header-filtered" />

20.

21.</Grid>

22.</Tooltip>

The above is how I have implemented my Grid with tooltips. My MailHeader component looks like:

1.class MailHeader extends React.Component<Readonly<MailHeaderProps>, {}> {

2. render() {

3. return (

4. <span title={this.props.title}>{this.props.title}</span>

5. );

6. }

7.}

But I get this error:

TS2326: Types of property 'headerCell' are incompatible.
Type 'typeof MailHeader' is not assignable to type 'ComponentType<GridHeaderCellProps>'.
Type 'typeof MailHeader' is not assignable to type 'StatelessComponent<GridHeaderCellProps>'.
Type 'typeof MailHeader' provides no match for the signature '(props: GridHeaderCellProps & { children?: ReactNode; }, context?: any):ReactElement<any>'.

Can anyone point me in the right direction to an answer or a possible clue?
