-#  How to maintain the component's state using Syncfusion DataManager
+# Syncfusion EJ2 Grid with Persistent State and Wishlist
 
-This demonstration shows how to connect multiple Syncfusion components to a single Syncfusion Datamanager and persist the current query based on user ID.
+## Repository Description
 
-## Run the application :
+This repository demonstrates how to build an interactive product dashboard using Syncfusion EJ2 components, combining Grid, Chart, and DataManager to persist user-specific state such as sorting, filtering, and wishlist selections.
 
-run the index.html in to your browser
+## Project Overview
+
+This project showcases a client-side web application that integrates multiple Syncfusion EJ2 UI components with a single DataManager instance. The application allows users to view product data in a grid, visualize customer reviews in a pie chart, and manage a personalized wishlist. User-specific state is persisted using the Syncfusion DataManager so that preferences are retained across sessions.
+
+The application is built using plain HTML, CSS, and JavaScript and relies on Syncfusion EJ2 CDN packages for UI components and data handling.
+
+## Key Features
+
+- Product listing using **Syncfusion EJ2 Grid**
+- Checkbox-based row selection with persistent selection
+- User-specific state persistence using **DataManager**
+- Sorting products by price (ascending and descending)
+- Category-based filtering using MultiSelect
+- Wishlist management per user
+- Pie chart visualization of customer reviews
+- Dynamic UI updates based on user actions
+
+## Prerequisites
+
+- A modern web browser (Chrome, Edge, Firefox)
+- Internet connection (to load Syncfusion CDN resources)
+
+## Running the Application
+
+1. Clone or download the repository.
+2. Ensure `index.html`, `sample.js`, `datasource.js`, and `index.css` are in the same directory.
+3. Open `index.html` directly in a browser.
+
+
+## Usage
+
+- Select a user from the dropdown to initialize the dashboard.
+- Use the sort buttons to order products by price.
+- Filter products by category using the filter dropdown.
+- Select products and add them to the wishlist.
+- View wishlist items and clear persisted data when required.
+- Logout to reset the session.
+
+## State Persistence
+
+The application uses Syncfusion DataManager persistence to store user-specific queries such as wishlist filters. Each user maintains an independent state identified by their username.
+
+## License
+
+This project is intended for demonstration and educational purposes using Syncfusion EJ2 components.
