Hi everyone,

Rendering columns within the `Grid` component using the `map` function is not working as expected. For example:
  • When defining the `GridColumn` properties, such as `cell`, the `className` property doesn't apply as expected. If I remove the cell property from the GridColumn component it works as expected.
  • If I don't explicitly define the `headerCell` property, the filter icon (three dots) isn't visible. Hence, I need to manually add the filter options in the header cell.

Note: Everything works as expected when I define each column component individually, without using the `map` function approach.

Objective: I need to display 20+ columns in the grid, and I want to avoid manually defining each `GridColumn` component. Instead, I would like to dynamically render the columns using the `map` function. In my case, the column headers are custom components, and the column filter functionality should be displayed conditionally.

Please find the attached file with implementation.

I kindly request your help. Thank you.

When start project after install deps I receive this error:
X [ERROR] Could not resolve "pdfjs-dist/build/pdf.worker.entry.js"

    node_modules/@progress/kendo-react-pdf-viewer/PDFViewer.mjs:20:7:
      20 │ import "pdfjs-dist/build/pdf.work...
         ╵        ~~~~~~~~~~~~~~~~~~~~~~~~~~

  You can mark the path
  "pdfjs-dist/build/pdf.worker.entry.js" as 
  external to exclude it from the bundle, which
  will remove this error.


Someone knows about that?

Im using the Gantt Chart libary for React

so what im trying to do is passing a custom date range props in the GanttWeekView

<GanttWeekView dateRange={calculateWeekDateRange}/>

the problem is whenever you pass custom dateRange props to the view, it will cause the date cell on the right not rerender correctly, for example the initial date is 12th September as shown in the pics below


and i change it to 5th, the date doesnt change as shown below,

for some reason i think whenever the custom dateRange passed, it wont rerender the whole Ganttview component if the date changed, any idea how i can fix this?

Currently, I am using a KeyboardEvent to programmatically press the right arrow inside of a DatePicker component.

This example works as expected:


I don't seem to be able to use KeyboardEvents to input numbers into the DatePicker. This example fails:

Hi,

I'm struggling with one issue, when both options filtering and suggestion are enabled, 'onFilterChange' is not triggering when the last character is filled in.

Code example: https://stackblitz.com/edit/react-tahdg9?file=app%2Fapp.tsx

Steps:

Enter: "1" -> event has been triggered

Enter: "11" -> event has been triggered

Enter: "111" -> event has been triggered

Enter: "1111" -> event has not been triggered

Hit backspace -> event has been triggered

Enter again: "1111" -> event has been triggered

Is it a bug or I'm doing something wrong? ;)

Hello,

 

I recently inherited an old project which was using v5 Kendo libraries. I have upgraded all of these to the latest as of today but in doing so I now am noticing a 'flash' of data before the correct data is rendered. I'm unable to produce a isolated demo but I will try my best to outline the components as minimally as possible.

 

Before I dive into the code what I have found is that a tableAction of 'getInnerTable' is being called to create and populate the "correct" data and the flash of incorrect data is actually the data supplied to the rowData prop on the Grid component.

 

Here's the code:

interfaceTableProps<T> { title?: string; tableModal?: { onClick: () =>void; text: string }; rowData: T[] | null; gridDefaultState: State; isLoading: boolean; tableActions: { removeItem?: (data: any) =>void; updateItem?: (data: any) =>void; getInnerTable: ( columnField: string, rowData: T[], isLastColumn: boolean, tableActions: { removeItem?: (data: T) => void; updateItem?: (data: T) => void; } ) =>ReactNode; }; children?: ReactNode; hasBorder?: boolean; } constTable = <T extends {}>({ isLoading, title, tableModal, rowData, gridDefaultState, tableActions, children, hasBorder = true, }: TableProps<T>) => { const [columnFields, setColumnFields] = useState<string[] | null>(null); const [gridDataState, setGridDataState] = useState<State>(gridDefaultState); console.log('rowData', rowData); useEffect(() => { if (rowData && rowData.length > 0) { setColumnFields([...Object.keys(rowData[0]), 'Icons']); } }, [rowData]); consthandleGridDataStateChange = (e: GridDataStateChangeEvent) => { setGridDataState({ ...e.dataState }); }; console.log('columnFields:', columnFields); constGridTable = () => { return ( <Grid data={rowData && process(rowData, gridDataState)} sortable={true} {...gridDataState} onDataStateChange={handleGridDataStateChange} selectable={{ enabled: true, mode: 'single', }} > {children} {rowData && columnFields?.map((columnField: string, index) => { console.log('columnField:', columnField); const isLastColumn: boolean = columnFields.length - 1 === index; return tableActions.getInnerTable(columnField, rowData, isLastColumn, tableActions); })} </Grid> ); }; return ( <StyledWrapper noData={!isLoading && !rowData?.length} hasBorder={hasBorder}> {title && <TitleWithButton title={title} buttonData={tableModal} hasBottomPadding />} {isLoading ? ( <SpinnerWrapper> <Spinner /> </SpinnerWrapper> ) : ( <GridTable /> )} </StyledWrapper> ); }; exportdefaultTable;

 

The getInnerTable function:

 


export const getOrganisationInnerTable = <T,>(
  columnField: string,
  rowData: Array<T & OrganisationColumn>,
  isLastColumn: boolean,
  tableActions: {
    removeItem?: (data: T) => void;
    updateItem?: (data: T) => void;
  }
) => {
  if (columnField === OrganisationStyledColumns.organisationName) {
    return (
      <GridColumn
        key={columnField}
        field="title.name"
        title={'Organisation name'}
        cell={(props: GridCellProps) => <OrganisationNameColumn {...props} />}
        columnMenu={(props) => ColumnFilterSearchMenu(rowData, props)}
      />
    );
  }

  if (columnField === OrganisationStyledColumns.createdDate) {
    return (
      <GridColumn
        key={columnField}
        field={columnField}
        title={'Added'}
        filter="date"
        format="{0:dd-MM-yyyy}"
        columnMenu={(props) => {
          return DateColumnFilter(rowData, props);
        }}
      />
    );
  }

  return getInnerTableColumn(columnField, rowData, isLastColumn, tableActions);
};

Dear  Reciever,

Just curious. Is this link(Globalization Support) up-to-date?
Because some components that are in kendo libraries are not listed in here.

Moreover, is this github repo show the available locale info?

Thanks.
Best Regards.

Hi,

 

If a Grid column is using number filter, its precision can only be 0.001. Is there a way to increase that?

See this Kendo React official example, the "Unit Price" filter can only take 0.001, not able to take 0.0001.

https://www.telerik.com/kendo-react-ui/components/grid/filtering/

 

I tried changing the column format to "{0:n6}", but it only affect the grid cell, not the filter.

 

Thanks,

Jie

I'm developing a system using React where users can create invoice templates using a drag-and-drop interface. I need help with the following:

  1. Template Storage Format: What is the best format for storing these templates on the backend?

  2. Backend Processing: Once the template is stored, the backend should be able to:

    • Receive the invoice amount and other relevant details.
    • Map these details to the selected template.
    • Generate a PDF based on the populated template.

Could you suggest an approach for handling these tasks effectively?
