Topic: MDBDataTable Previous Next issue

Jigar Kothari free asked 5 years ago


**Expected behavior**

Previous should be disabled if the user is on the First page of the data table. Next should be disabled if the user is on the Last page of the data table.

**Actual behavior**

Previous button shows the disabled cursor, but when clicked Previous on the First page, the app crashes.When on the last page, if Next is clicked it still moves ahead to show a blank Data table.

**Resources (screenshots, code snippets etc.)**

Thanks,

I've checked your code. The problem is caused because the MDB styles are not attached in App or index.js. More read here: https://mdbootstrap.com/docs/react/getting-started/quick-start/

It should look like this:

import React from 'react';
import ReactDOM from 'react-dom';
// mdb & bootstrap styles
import '@fortawesome/fontawesome-free/css/all.min.css';
import 'bootstrap-css-only/css/bootstrap.min.css';
import 'mdbreact/dist/css/mdb.css';

import App from './App';
import * as serviceWorker from './serviceWorker';

ReactDOM.render(<App />, document.getElementById('root'));

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: https://bit.ly/CRA-PWA
serviceWorker.unregister();

But that showed up the problem with default styles for the pagination component which we should fix.

Hope this will help.

Best,

Jakub

Hi Jakub,

Thanks for the reply. Importing css did help, but importing those files have overridden my previous styling throughout the site. Trying to rectify that. Please let me know if I can get a small patch of css styling related to the Datatable and pagination only rather than importing the whole stylesheet.

Thanks for the help.

Hey,

You could clone our repo or download the zipped starter project https://mdbootstrap.com/docs/react/getting-started/download/

There are our scss files, which you could edit. Also, you have there an _custom-styles.scss file, where you can attach your custom styles.

In imports in mdb.scss file, you can remove modules which you do not need.

Best,

Jakub

Hi,

I can not reproduce the issue. Can you provide us with error logs and code snippet with your Datatable implementation please?

Best,

Jakub

Hi Jakub,Appreciate your reply. Please find the usage and the error log

We have never met a similar error in our package, so it is hard to tell what could be wrong.

Looks like the problem is connected with the project configuration. Do you use create-react-app or your custom config? Or maybe SSR?

It would be good if you share the project on Github and share it with us (it can be private, just add mdbootstrap as collaborator), so we could clone and debug.

Best,

Jakub


Jigar Kothari free commented 5 years ago

Hi Jakub,

Thanks for the reply. I won't be able to share the original code, but instead have created a demo wherein the same issue persists. Please check your Git account for the collaborator invitation. Also I am using create-react-app.


Jakub Mandra staff commented 5 years ago

Hi Jigar,

I'm sorry but it comes out that I'm not able to use @mdbootstrap account, I will have to use my private. So please invite @rotarepmi.

Best regards,

Jakub
