Dynamically filling the Rowcount property in the DataGridProps.

Hi, I am following the blog_posts example that shows data using the DataGrid on a selection of (external) filters with an API. I am trying to fill the RowCount dynamically based on the results returned in the filters. I have noticed that this could be set in the DataGridProps, but I am not entirely sure how to pass the row count from the API to the existing DataProvider, as the dataprovider only seems to accept an array of data points as rows for the grid. I would expect the solution would be to add a total Rowcount to the results API, but I am not able to parse it somewhere automagically and use it in my front-end. Hope you guys can shed some light on my situation and looking forward to a reponse!

Hi @prikkel.. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hi, To dynamically set the rowCount based on the results returned from the API, you can use the useList hook, which fetches the data and the total number of data. The useDataGrid hook internally uses the useList hook to fetch the data and the total count. When you use the useDataGrid hook, it returns an object containing dataGridProps. This object includes the rows and rowCount properties, which are fetched using the useList hook source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid). Here's an example of how you can use the useDataGrid hook in your component:

import React from 'react';
import { useDataGrid, DataGrid, GridColumns } from '@refinedev/mui';

const Table: React.FC = () => {
  const { dataGridProps } = useDataGrid();
  const columns: GridColumns = [
    {
      field: 'id',
      headerName: 'ID',
    },
    {
      field: 'name',
      headerName: 'Name',
    },
    {
      field: 'Age',
      headerName: 'Age',
    },
  ];

  return (
    <DataGrid {...dataGridProps} columns={columns} autoHeight />
  );
};

export default Table;

import React from 'react';
import { useDataGrid, DataGrid, GridColumns } from '@refinedev/mui';

const Table: React.FC = () => {
  const { dataGridProps } = useDataGrid();
  const columns: GridColumns = [
    {
      field: 'id',
      headerName: 'ID',
    },
    {
      field: 'name',
      headerName: 'Name',
    },
    {
      field: 'Age',
      headerName: 'Age',
    },
  ];

  return (
    <DataGrid {...dataGridProps} columns={columns} autoHeight />
  );
};

export default Table;

In this example, you don't need to pass the rows or rowCount prop to the <DataGrid/> component, as the dataGridProps variable automatically injects the rows and rowCount values into the <DataGrid> component source (https://refine.dev/blog/mui-datagrid-refine). To make sure the rowCount is updated based on the API results, you need to ensure that your data provider is correctly configured to fetch the data and the total count. The dataProvider prop in the <Refine/> component is responsible for reading data from an API endpoint and making it available throughout the application source (https://refine.dev/blog/mui-datagrid-refine). If you need more information on how to configure your data provider, you can refer to the data provider documentation (https://refine.dev/docs/tutorial/understanding-dataprovider/index). I hope this helps! Let me know if you have any further questions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
