DataGridPro paginationMode: server

Hello, I'm currently using DataGridPro with paginationMode set to "server", in conjunction with the useMany hook and a REST API. My question revolves around sending the correct rowCount from my endpoint. I've noticed that when I send rows from my backend, they are assigned to the rows property in the dataGridProps. Could you please guide me on how I should appropriately set and send the rowCount from my backend to ensure it is correctly interpreted by DataGridPro? Thank you in advance for your help.

---------------------- To ensure that the rowCount is correctly interpreted by DataGridPro, you need to send the total number of data from your backend. The rowCount value is fetched with the useList hook in refine source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid#dataGridProps-rowCount). When using the useMany hook with a REST API, you should make sure that your API endpoint returns the total number of records along with the data. The response should include both the data array and the total count of records. Refine will then automatically assign the rowCount value to the dataGridProps. For example, your API response should look like this:

{
  "data": [
    // Your data records here
  ],
  "total": 100 // Total number of records
}

{
  "data": [
    // Your data records here
  ],
  "total": 100 // Total number of records
}

By returning the data and total count in this format, refine will be able to correctly interpret the rowCount for DataGridPro. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

By using useDataGrid, you can get properties that are compatible with MUI X component. All features such as sorting, filtering, and pagination come out of the box. Under the hood it uses useList for the fetch.

@kapa.ai I tried your suggestion, but when I send the data array and total count from my backend in the suggested format, dataGridProps is now treating rows as an object that looks like this:

{
  "data": [...the rows],
  "total": the total count
}

{
  "data": [...the rows],
  "total": the total count
}

Subsequently, I am encountering an error: Failed prop type: Invalid prop 'rows' of type 'object' supplied to ForwardRef(DataGridPro), expected an array. To circumvent this, I am considering destructuring rows from the dataGridProps and entering these values separately as props in the DataGridPro component. Would this be a recommended approach or is there another preferred method to resolve this issue?

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can destructure the rows and total from the dataGridProps and pass them separately as props to the DataGridPro component. This approach should resolve the issue you're facing. Here's an example of how you can do this:

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure rows and total from dataGridProps
  const { rows, total } = dataGridProps;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={rows?.data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure rows and total from dataGridProps
  const { rows, total } = dataGridProps;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={rows?.data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

By destructuring the rows and total from dataGridProps and passing them separately to the DataGridPro component, you should be able to avoid the prop type error and correctly display the data with server-side pagination. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the data is actually

rows: {
data: [all the rows],
total: total count
}

rows: {
data: [all the rows],
total: total count
}

in dataGripProps but I will take this approach all the same and with TypeScript I haven't looked at how to handle things yet, since for the ids prop I will have to do datagridProps?.rows?.data?map - is that correct? Something like that I will get back to you, I'm a little tired

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I understand that the dataGridProps has the following structure:

rows: {
  data: [all the rows],
  total: total count
}

rows: {
  data: [all the rows],
  total: total count
}

In this case, you can destructure the data and total from dataGridProps.rows and pass them separately as props to the DataGridPro component. Here's an example of how you can do this with TypeScript:

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows
  const { data, total } = dataGridProps.rows;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows
  const { data, total } = dataGridProps.rows;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

Regarding the ids prop, if you need to map over the data array, you can do it like this:

data?.map((row) => {
  // Your logic here
});

data?.map((row) => {
  // Your logic here
});

This approach should work well with TypeScript and help you avoid any issues related to the prop types. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Yeah I see the rows?.data in the other response now. Didn't read it correctly

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm glad you found the previous response helpful. Just to reiterate, you can destructure the data and total from dataGridProps.rows and pass them separately as props to the DataGridPro component. Here's the example with TypeScript:

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows
  const { data, total } = dataGridProps.rows;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows
  const { data, total } = dataGridProps.rows;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

And for mapping over the data array, you can use:

data?.map((row) => {
  // Your logic here
});

data?.map((row) => {
  // Your logic here
});

@kapa.ai when I try to destructure

  const {data, total} = dataGridProps.rows;

  const {data, total} = dataGridProps.rows;

I get this TypeScript error Property 'data' does not exist on type 'readonly any[]'.ts(2339)

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I apologize for the confusion. It seems that the TypeScript error is due to the type of dataGridProps.rows. To fix this issue, you can use type assertions to specify the expected structure of dataGridProps.rows. Here's an example:

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

interface RowsData {
  data: any[];
  total: number;
}

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows using type assertion
  const { data, total } = dataGridProps.rows as RowsData;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

import React from "react";
import { useMany } from "@refinedev/core";
import { List, useDataGrid } from "@refinedev/mui";
import { DataGridPro } from "@mui/x-data-grid-pro";

interface RowsData {
  data: any[];
  total: number;
}

const SampleList: React.FC = () => {
  const { dataGridProps } = useDataGrid();

  // Destructure data and total from dataGridProps.rows using type assertion
  const { data, total } = dataGridProps.rows as RowsData;

  // Define your columns here
  const columns = [
    // Your column definitions
  ];

  return (
    <List>
      <DataGridPro
        {...dataGridProps}
        rows={data || []} // Pass the data array as rows
        rowCount={total} // Pass the total count as rowCount
        columns={columns}
        autoHeight
      />
    </List>
  );
};

By using the RowsData interface and type assertion, you should be able to destructure data and total without encountering the TypeScript error. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I'm still learning TypeScript so I'm getting used to things. I have tried to do this:

type RowsData = {
  data: any[],
  total: number
 }

type RowsData = {
  data: any[],
  total: number
 }

and then destructure

const {data, total} = dataGridProps.rows as RowsData;

const {data, total} = dataGridProps.rows as RowsData;

and I get this error: Conversion of type 'readonly any[]' to type 'RowsData' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first. Type 'readonly any[]' is missing the following properties from type 'RowsData': data, totalts(2352) (property) rows: readonly any[] Set of rows of type [[GridRowsProp]]. I am using type since everyone uses that at work!

Let me check the knowledge base for you. One moment! :books: @darshan_sandhu That's a great question, but unfortunately I am only capable of responding to a maximum of three questions per thread. Don't hesitate to create a new thread for any further questions you have though. I'm here to help!

flat-fuchsiaOP•2y ago

@kapa.ai I added unknown before as RowsData and it's working, but it feels hacky? I don't know enough about TypeScript yet. This message is for anyone who reads this**

kapa.ai•2y ago

flat-fuchsia•2y ago

Hey @darshan_sandhu, You can use generics of useDataGrid hook like below: useDataGrid<RowsData>(…)

Awesome, thank you!
