Quick Start Example

⚠️ Dependency Alignment: All @syncfusion/ej2-* packages must be on the same major version to avoid peer-dependency conflicts and supply-chain mismatches. Install them together:

npm install @syncfusion/ej2-react-popups @syncfusion/ej2-base @syncfusion/ej2-buttons @syncfusion/ej2-popups

Basic Modal Dialog:

import React, { useRef, useState } from 'react';
import { DialogComponent } from '@syncfusion/ej2-react-popups';
import '@syncfusion/ej2-base/styles/material.css';
import '@syncfusion/ej2-buttons/styles/material.css';
import '@syncfusion/ej2-popups/styles/material.css';

export default function App() {
  const dialogRef = useRef(null);
  const [isOpen, setIsOpen] = useState(false);

  const handleOpen = () => {
    dialogRef.current?.show();
    setIsOpen(true);
  };

  const handleClose = () => {
    dialogRef.current?.hide();
    setIsOpen(false);
  };

  const buttons = [
    {
      buttonModel: {
        content: 'OK',
        cssClass: 'e-flat',
        isPrimary: true,
      },
      click: handleClose,
    },
    {
      buttonModel: {
        content: 'Cancel',
        cssClass: 'e-flat',
      },
      click: handleClose,
    },
  ];

  return (
    <div id="dialog-target" style={{ position: 'relative', width: '100%', minHeight: '400px' }}>
      <button onClick={handleOpen} className="e-control e-btn e-primary">
        Open Dialog
      </button>

      <DialogComponent
        ref={dialogRef}
        header="Confirm Action"
        buttons={buttons}
        showCloseIcon={true}
        target="#dialog-target"
        width="400px"
        isModal={true}
        visible={false}
      >
        <p>Are you sure you want to proceed with this action?</p>
      </DialogComponent>
    </div>
  );
}

Common Patterns

Pattern 1: Confirmation Dialog

Delete action with confirmation buttons:

const buttons = [
  {
    buttonModel: { content: 'Delete', cssClass: 'e-flat e-danger', isPrimary: true },
    click: () => { performDelete(); dialogRef.current?.hide(); }
  },
  {
    buttonModel: { content: 'Cancel', cssClass: 'e-flat' },
    click: () => dialogRef.current?.hide()
  }
];

Pattern 2: Form Dialog

Dialog with form inputs and validation:

<DialogComponent header="Edit Profile" buttons={buttons} isModal={true} width="500px">
  <div style={{ padding: '16px' }}>
    <input type="text" placeholder="Name" className="form-control" />
    <input type="email" placeholder="Email" className="form-control" />
    <textarea placeholder="Bio" className="form-control"></textarea>
  </div>
</DialogComponent>

Pattern 3: Centered Dialog

Position dialog in center of screen:

<DialogComponent
  header="Alert"
  position={{ X: 'center', Y: 'center' }}
  isModal={true}
  showCloseIcon={true}
  width="350px"
>
  This dialog is centered on the screen.
</DialogComponent>

Pattern 4: Draggable Floating Panel

Non-modal, draggable properties panel:

<DialogComponent
  header="Properties"
  isModal={false}
  allowDragging={true}
  position={{ X: 200, Y: 150 }}
  width="300px"
  enableResize={true}
  resizeHandles={['All']}
  showCloseIcon={true}
>
  Drag me around! I don't block the page.
</DialogComponent>

Pattern 5: Animated Dialog

Dialog with Zoom animation:

<DialogComponent
  header="Welcome"
  animationSettings={{ effect: 'Zoom', duration: 400, delay: 0 }}
  isModal={true}
  position={{ X: 'center', Y: 'center' }}
  width="400px"
>
  This dialog zooms in smoothly!
</DialogComponent>

Pattern 6: Custom Footer Template

Custom footer instead of buttons:

<DialogComponent
  header="Custom Footer"
  isModal={true}
  footerTemplate={
    <div style={{ padding: '12px', textAlign: 'right' }}>
      <button className="e-control e-btn e-primary" style={{ marginRight: '8px' }}>
        Save
      </button>
      <button className="e-control e-btn">Cancel</button>
    </div>
  }
>
  Dialog content with custom footer.
</DialogComponent>

Pattern 7: Nested Dialogs

Parent dialog containing child dialog:

const childDialogRef = useRef(null);

<DialogComponent header="Parent" isModal={true} width="400px">
  <button onClick={() => childDialogRef.current?.show()} className="e-control e-btn">
    Open Child Dialog
  </button>
  
  <DialogComponent
    ref={childDialogRef}
    header="Child"
    isModal={true}
    width="300px"
    visible={false}
  >
    Nested dialog content
  </DialogComponent>
</DialogComponent>

Implementing Syncfusion React Predefined Dialog Component

Table of Contents

• Key Concept
• Quick Start
• Documentation Guide
• Common Patterns

Key Concept

Syncfusion Predefined Dialogs are not component-based (<ejs-dialog>). They are opened imperatively via the DialogUtility utility class:

Dialog Type	Method
Alert	DialogUtility.alert({ ... })
Confirm	DialogUtility.confirm({ ... })
Prompt (input)	DialogUtility.confirm({ content: '<input .../>', ... })

Import: import { DialogUtility } from '@syncfusion/ej2-react-popups';

---

Quick Start

import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { DialogUtility } from '@syncfusion/ej2-react-popups';
import * as React from 'react';

function App() {
  function showAlert() {
    DialogUtility.alert({
      title: 'Low Battery',
      width: '250px',
      content: '10% of battery remaining',
    });
  }
  return <ButtonComponent cssClass="e-danger" onClick={showAlert}>Alert</ButtonComponent>;
}
export default App;

Common Patterns

Alert with OK callback:

const dialogObj = DialogUtility.alert({
  title: 'Info',
  content: 'Operation complete.',
  okButton: { click: () => { dialogObj.hide(); } }
});

Confirm with Yes / No:

const dialogObj = DialogUtility.confirm({
  title: 'Delete?',
  content: 'Are you sure?',
  width: '300px',
  okButton: { text: 'Yes', click: () => { dialogObj.hide(); /* do delete */ } },
  cancelButton: { text: 'No', click: () => { dialogObj.hide(); } }
});

Prompt (input capture):

const dialogObj = DialogUtility.confirm({
  title: 'Enter Name',
  content: '<p>Your name:</p><input id="nameInput" class="e-input" placeholder="Type here..." />',
  width: '300px',
  okButton: {
    text: 'Submit',
    click: () => {
      const val = (document.getElementById('nameInput') as HTMLInputElement).value;
      dialogObj.hide();
    }
  },
  cancelButton: { click: () => dialogObj.hide() }
});

function App() {
  let tooltipRef: TooltipComponent;
  const target = React.useRef<HTMLButtonElement>(null);

  return (
    <TooltipComponent
      ref={t => (tooltipRef = t)}

      opensOn="Custom"
    >
      <button
        ref={target}
        className="e-btn"
        onClick={() => {
          if (target.current.getAttribute('data-tooltip-id')) {
            tooltipRef.close();
          } else {
            tooltipRef.open(target.current);
          }
        }}
      >
        Toggle Tooltip
      </button>
    </TooltipComponent>
  );
