5. Adding Delete Feature

Adding Delete Feature to List Page

<DeleteButton/> is a refine component that is used for deleting records. When you click on the delete button, it will show a confirmation modal and delete the record upon confirmation. To add it to the "blog_posts" table:

Open the src/pages/blog-posts/list.tsx file on your editor.
Import the <DeleteButton/> component from @refinedev/mui:
```
import { DeleteButton } from "@refinedev/mui";
```

Add the <DeleteButton/> component to the actions column of the table as shown below:

{
    field: "actions",
    headerName: "Actions",
    renderCell: function render({ row }) {
        return (
            <>
                <EditButton hideText recordItemId={row.id} />
                <ShowButton hideText recordItemId={row.id} />
                <DeleteButton hideText recordItemId={row.id} />
            </>
        );
    },
    align: "center",
    headerAlign: "center",
    minWidth: 80,
},

You can now delete a record from the list page by clicking on the delete button of any blog post.

For more information, refer to the <DeleteButton/> documentation→

Enabling the Delete Feature on Show and Edit Pages

We can enable the delete feature on both show and edit pages while we are defining a resource by setting the canDelete property in the meta to true as shown below:

import { Refine } from "@refinedev/core";
import {
    Layout,
    ErrorComponent,
    LightTheme,
    RefineSnackbarProvider,
    notificationProvider,
} from "@refinedev/mui";
import { CssBaseline, GlobalStyles, ThemeProvider } from "@mui/material";
import routerBindings from "@refinedev/react-router-v6";
import dataProvider from "@refinedev/simple-rest";

import { BrowserRouter, Routes, Route, Outlet } from "react-router-dom";

import { BlogPostList } from "pages/blog-posts/list";
import { BlogPostEdit } from "pages/blog-posts/edit";
import { BlogPostShow } from "pages/blog-posts/show";
import { BlogPostCreate } from "pages/blog-posts/create";

const App: React.FC = () => {
    return (
        <ThemeProvider theme={LightTheme}>
            <CssBaseline />
            <GlobalStyles styles={{ html: { WebkitFontSmoothing: "auto" } }} />
            <RefineSnackbarProvider>
                <BrowserRouter>
                    <Refine
                        routerProvider={routerBindings}
                        dataProvider={dataProvider(
                            "https://api.fake-rest.refine.dev",
                        )}
                        notificationProvider={notificationProvider}
                        resources={[
                            {
                                name: "blog_posts",
                                list: "/blog-posts",
                                show: "/blog-posts/show/:id",
                                create: "/blog-posts/create",
                                edit: "/blog-posts/edit/:id",
                                meta: {
                                    canDelete: true,
                                },
                            },
                        ]}
                    >
                        {/* ... */}
                    </Refine>
                </BrowserRouter>
            </RefineSnackbarProvider>
        </ThemeProvider>
    );
};
export default App;

After setting the canDelete property in meta to true, you will see a delete button on both show and edit pages.

For more information, refer to the canDelete section of the <Refine/> documentation→

TIP

You can also use useDelete hook provided by refine to delete a record.
