Solving the Mysterious Case of the Radiobutton that Appears Twice in Primereact Datatable with ReactJS

If you’re reading this, chances are you’ve stumbled upon a frustrating issue that’s got you scratching your head – the radiobutton appears twice in your Primereact Datatable when using ReactJS. Don’t worry, you’re not alone! In this article, we’ll dive into the root cause of this issue and provide a step-by-step guide on how to fix it.

What’s Causing the Radiobutton to Appear Twice?

Before we dive into the solution, let’s understand why this issue occurs in the first place. The Primereact Datatable is a powerful component that allows you to easily display and manipulate data in a tabular format. However, when using radiobuttons as a column type, it’s not uncommon for the radiobutton to appear twice, especially when using ReactJS.

There are a few reasons why this might happen:

• Incorrectly configured column definitions
• Clashing CSS styles
• Incompatibility with ReactJS versions
• Overzealous JSX rendering

Step 1: Review Your Column Definitions

To start, let’s take a closer look at your column definitions. Make sure you’ve correctly defined the radiobutton column type and specified the correct properties.

import React from 'react';
import { DataTable } from 'primereact/datatable';
import { Column } from 'primereact/column';

const columns = [
  {
    field: 'id',
    header: 'ID'
  },
  {
    field: 'name',
    header: 'Name'
  },
  {
    field: 'selection',
    header: 'Select',
    body: (rowData) => {
      return (
         {
            console.log(e.target.value);
          }}
        />
      );
    }
  }
];

const data = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' }
];

const DataTableExample = () => {
  return (
    
  );
};

export default DataTableExample;

In the above example, we’ve defined a simple DataTable with three columns: id, name, and selection. The selection column uses a radiobutton as its body component.

Step 2: Inspect Your CSS Styles

Sometimes, clashing CSS styles can cause the radiobutton to appear twice. Inspect your CSS files and check if there are any styles that might be affecting the radiobutton’s rendering.

Try adding the following CSS rule to your stylesheet:

.p-datatable tbody tr td {
  position: relative;
}

.p-datatable tbody tr td input[type="radio"] {
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
  cursor: pointer;
}

.p-datatable tbody tr td input[type="radio"] + label {
  position: relative;
  display: inline-block;
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  cursor: pointer;
}

This CSS rule sets the radiobutton’s position to absolute and hides it, while keeping the label visible. This should prevent the radiobutton from appearing twice.

Step 3: Check Your ReactJS Version

If you’re using an older version of ReactJS, it might be incompatible with the Primereact Datatable. Make sure you’re using the latest version of ReactJS and Primereact.

Try updating your package.json file to the latest version:

"dependencies": {
  "react": "^17.0.2",
  "react-dom": "^17.0.2",
  "primereact": "^7.1.3"
}

Step 4: Optimize Your JSX Rendering

Sometimes, overzealous JSX rendering can cause the radiobutton to appear twice. Try optimizing your JSX rendering by using the `key` prop and memoizing your components.

import React, { memo } from 'react';

const DataTableExample = memo(() => {
  return (
    <DataTable value={data} columns={columns} />
  );
});

export default DataTableExample;

In the above example, we’ve wrapped our DataTable component in a `memo` function, which ensures that the component is only re-rendered when its props change.

Solution: Putting it all Together

Now that we’ve addressed the potential causes of the issue, let’s put it all together! Here’s the complete code example:

import React, { memo } from 'react';
import { DataTable } from 'primereact/datatable';
import { Column } from 'primereact/column';

const columns = [
  {
    field: 'id',
    header: 'ID'
  },
  {
    field: 'name',
    header: 'Name'
  },
  {
    field: 'selection',
    header: 'Select',
    body: (rowData) => {
      return (
        <input
          type="radio"
          name="selection"
          value={rowData.id}
          onChange={(e) => {
            console.log(e.target.value);
          }}
        />
      );
    }
  }
];

const data = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' }
];

const DataTableExample = memo(() => {
  return (
    <DataTable value={data} columns={columns} />
  );
});

export default DataTableExample;

By following these steps, you should be able to solve the issue of the radiobutton appearing twice in your Primereact Datatable with ReactJS.
