-# ASP.MET CORE DataGrid - Cascading Dropdown Remote Data Editing in Data Binding
+# EJ2-Grid-Core-dotnet3-databinding-remote
 
-This sample explains about how to achieve the cascading dropdown with remote data-binding in the ASP.NET Core DataGrid inline editing.
+## Repository Description
+
+This repository contains an ASP.NET Core 3 sample application that demonstrates rendering the EJ2 DataGrid component with remote data binding. The project focuses on server-side data integration and grid rendering using the Syncfusion EJ2 library.
+
+## Project Overview
+
+The application illustrates the usage of the EJ2 Grid within a .NET Core 3 framework. Data is retrieved from a remote source and bound to the grid at runtime. The sample highlights the interaction between the controller and the client-side grid component, making it suitable for understanding remote data scenarios in enterprise web applications.
+
+## Features
+
+- EJ2 Grid integration with ASP.NET Core 3
+- Remote data binding through server endpoints
+- Initial grid rendering with server-provided data
+- Minimal and clean configuration setup
 
 ## Prerequisites
 
-* Visual Studio 2022
+- .NET Core SDK 3.x
+- Visual Studio 2019 or later
+- Basic understanding of ASP.NET Core MVC
+- EJ2 dependencies referenced in the project
+
+## Installation
+
+1. Clone the repository to the local system.
+    ```
+    git clone <repo_link>
+    ```
+2. Open the solution file in Visual Studio.
+3. Restore NuGet packages to resolve required dependencies.
+4. Run the application.
+
+
+## Usage
 
-## How to run the project
+When the application starts, the grid requests data from the configured server endpoint. The response is processed and displayed within the EJ2 Grid component.
 
-* Checkout this project to a location in your disk.
-* Open the solution file using the Visual Studio 2022.
-* Restore the NuGet packages by rebuilding the solution.
-* Run the project.
