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() }
});

Common Patterns
Tooltip on a Button
<TooltipComponent content="Submit the form" position="TopCenter">
<button className="e-btn e-primary">Submit</button>
</TooltipComponent>
Multi-Target Tooltip in a Container
// Single TooltipComponent handles all .e-info targets;
// each uses its own `title` attribute as content
<TooltipComponent target=".e-info" position="RightCenter">
<form>
<input className="e-info" type="text" title="Enter your name" />
<input className="e-info" type="email" title="Enter a valid email" />
</form>
</TooltipComponent>
Click-Triggered Sticky Tooltip
<TooltipComponent
content="Click the × to close me"
opensOn="Click"
isSticky={true}
position="BottomCenter"
>
<button className="e-btn">Click Me</button>
</TooltipComponent>
Programmatic Open/Close
import * as React from 'react';
import { TooltipComponent } from '@syncfusion/ej2-react-popups';
function App() {
let tooltipRef: TooltipComponent;
const target = React.useRef<HTMLButtonElement>(null);
return (
<TooltipComponent
ref={t => (tooltipRef = t)}
content="Tooltip opened programmatically"
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>
);
}
Mouse-Trailing Tooltip
<TooltipComponent
content="Following your mouse!"
mouseTrail={true}
showTipPointer={false}
>
<div style={{ width: '200px', height: '100px', background: '#eee' }}>
Hover over me
</div>
