21 Feb 20265 minutes to read

Customize the progress bar appearance—including size, color, and background—by overriding the default Uploader component styles. The following example demonstrates how to apply custom CSS to match your application theme.

index.jsx

import { UploaderComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDOM from "react-dom";
export default class App extends React.Component {
    uploadObj;
    path = {
        removeUrl: 'https://services.syncfusion.com/react/production/api/FileUploader/Remove',
        saveUrl: 'https://services.syncfusion.com/react/production/api/FileUploader/Save'
    };
    dropAreaRef;
    onCreated() {
        this.uploadObj.dropArea = this.dropAreaRef;
        this.uploadObj.dataBind();
    }
    render() {
        return (<div className='control-pane' ref={dropAreaEle => this.dropAreaRef = dropAreaEle}>
            <div className='control-section row uploadpreview'>
            <div className='col-lg-9'>
            <div className='upload_wrapper custom_progress' id="container">
                {/* Render Uploader */}
                <UploaderComponent id='fileUpload' type='file' ref={upload => { this.uploadObj = upload; }} asyncSettings={this.path} created={this.onCreated = this.onCreated.bind(this)}/>
            </div>
            </div>
            </div>
        </div>);
    }
}
ReactDOM.render(<App />, document.getElementById('fileupload'));

index.tsx

import { UploaderComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDOM from "react-dom";

export default class App extends React.Component<{}, {}> {
  public uploadObj: UploaderComponent;
  public path: object = {
      removeUrl: 'https://services.syncfusion.com/react/production/api/FileUploader/Remove',
      saveUrl: 'https://services.syncfusion.com/react/production/api/FileUploader/Save'
  }
  private dropAreaRef: HTMLElement;
  public onCreated(): void {
    this.uploadObj.dropArea = this.dropAreaRef;
    this.uploadObj.dataBind();
  }
    public render(): JSX.Element {
        return (
        <div className = 'control-pane' ref={dropAreaEle => this.dropAreaRef = dropAreaEle!}>
            <div className='control-section row uploadpreview'>
            <div className='col-lg-9'>
            <div className='upload_wrapper custom_progress' id="container">
                {/* Render Uploader */}
                <UploaderComponent id='fileUpload' type='file' ref = {upload => {this.uploadObj = upload !}}
                asyncSettings = {this.path} created={this.onCreated = this.onCreated.bind(this)}
                />
            </div>
            </div>
            </div>
        </div>
        )
    }
}

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