Show

<Show> provides us a layout for displaying the page. It does not contain any logic but adds extra functionalities like a refresh button or giving title to the page.

We will show what <Show> does using properties with examples.

http://localhost:3000
import React from "react";
import { useShow, useOne } from "@refinedev/core";
import {
    Show,
    NumberField,
    TextFieldComponent as TextField,
    MarkdownField,
    DateField,
} from "@refinedev/mui";
import { Stack, Typography } from "@mui/material";

const SampleShow = () => {
    const { queryResult } = useShow();
    const { data, isLoading } = queryResult;

    const record = data?.data;

    const { data: categoryData, isLoading: categoryIsLoading } = useOne({
        resource: "categories",
        id: record?.category?.id || "",
        queryOptions: {
            enabled: !!record,
        },
    });

    return (
        <Show isLoading={isLoading}>
            <Stack gap={1}>
                <Typography variant="body1" fontWeight="bold">
                    Id
                </Typography>
                <NumberField value={record?.id ?? ""} />
                <Typography variant="body1" fontWeight="bold">
                    Title
                </Typography>
                <TextField value={record?.title} />
                <Typography variant="body1" fontWeight="bold">
                    Content
                </Typography>
                <MarkdownField value={record?.content} />
                <Typography variant="body1" fontWeight="bold">
                    Category
                </Typography>
                {categoryIsLoading ? (
                    <>Loading...</>
                ) : (
                    <>{categoryData?.data?.title}</>
                )}
                <Typography variant="body1" fontWeight="bold">
                    Created At
                </Typography>
                <DateField value={record?.createdAt} />
            </Stack>
        </Show>
    );
};
Swizzle

You can swizzle this component to customize it with the refine CLI

Properties​

title​

It allows adding title inside the <Show> component. if you don't pass title props it uses the "Show" prefix and the singular resource name by default. For example, for the "posts" resource, it will be "Show post".

http://localhost:3000
import { Show } from "@refinedev/mui";
import { Typography } from "@mui/material";

const ShowPage: React.FC = () => {
    return (
        <Show
            title={<Typography variant="h5">Custom Title</Typography>}
        >
            <span>Rest of your page here</span>
        </Show>
    );
};

resource​

The <Show> component reads the resource information from the route by default. If you want to use a custom resource for the <Show> component, you can use the resource prop.

http://localhost:3000
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
    return (
        <Show resource="posts" recordItemId={123}>
            <span>Rest of your page here</span>
        </Show>
    );
};

canDelete and canEdit​

canDelete and canEdit allows us to add the delete and edit buttons inside the <Show> component. If the resource has canDelete or canEdit property refine adds the buttons by default.

When clicked on, delete button executes the useDelete method provided by the dataProvider and the edit button redirects the user to the record edit page.

Refer to the <DeleteButton> and the <EditButton> documentation for detailed usage.

http://localhost:3000
import { Show } from "@refinedev/mui";
import { usePermissions } from "@refinedev/core";

const PostShow: React.FC = () => {
    const { data: permissionsData } = usePermissions();
    return (
        <Show
            canDelete={permissionsData?.includes("admin")}
            canEdit={
                permissionsData?.includes("editor") ||
                permissionsData?.includes("admin")
            }
        >
            <p>Rest of your page here</p>
        </Show>
    );
};

Refer to the usePermission documentation for detailed usage. &#8594

recordItemId​

<Show> component reads the id information from the route by default. recordItemId is used when it cannot read from the URL (when used on a custom page, modal or drawer).

http://localhost:3000
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
    return (
        <Show resource="posts" recordItemId={123}>
            <span>Rest of your page here</span>
        </Show>
    );
};
note

<Show> component needs the id information for <RefreshButton> to work properly.

caution

The <Show> component needs the id information for work properly, so if you use the <Show> component in custom pages, you should pass the recordItemId property.

dataProviderName​

If not specified, Refine will use the default data provider. If you have multiple data providers and want to use a different one, you can use the dataProviderName property.

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";

import { Show } from "@refinedev/mui";

const PostShow = () => {
    return <Show dataProviderName="other">...</Show>;
};

export const App: React.FC = () => {
    return (
        <Refine
            dataProvider={{
                default: dataProvider("https://api.fake-rest.refine.dev/"),
                other: dataProvider("https://other-api.fake-rest.refine.dev/"),
            }}
        >
            {/* ... */}
        </Refine>
    );
};

goBack​

To customize the back button or to disable it, you can use the goBack property.

http://localhost:3000
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";
import { useBack } from "@refinedev/core";

const BackButton = () => {
    const goBack = useBack();

    return <Button onClick={() => goBack()}>BACK!</Button>;
};

const PostShow: React.FC = () => {
    return (
        <Show
            goBack={<BackButton />}
        >
            <span>Rest of your page here</span>
        </Show>
    );
};

isLoading​

To toggle the loading state of the <Show/> component, you can use the isLoading property.

http://localhost:3000
import { Show } from "@refinedev/mui";

const PostShow: React.FC = () => {
    const [loading, setLoading] = React.useState(true);

    return (
        <Show
            isLoading={loading}
        >
            <span>Rest of your page here</span>
        </Show>
    );
};

To customize or disable the breadcrumb, you can use the breadcrumb property. By default it uses the Breadcrumb component from @refinedev/mui package.

Refer to the Breadcrumb documentation for detailed usage. &#8594

tip

This feature can be managed globally via the <Refine> component's options

http://localhost:3000
import { Show, Breadcrumb } from "@refinedev/mui";

const PostShow: React.FC = () => {
    return (
        <Show
            breadcrumb={
                <div
                    style={{
                        padding: "3px 6px",
                        border: "2px dashed cornflowerblue",
                    }}
                >
                    <Breadcrumb />
                </div>
            }
        >
            <span>Rest of your page here</span>
        </Show>
    );
};

                sx: {
                    backgroundColor: "lightsteelblue",
                },
            }}
