-# ASP.MET CORE DataGrid - Cascading Dropdown Remote Data Editing in Data Binding
+# EJ2 DataGrid Cascading DropDown with Remote Data (ASP.NET Core)
 
-This sample explains about how to achieve the cascading dropdown with remote data-binding in the ASP.NET Core DataGrid inline editing.
+This repository demonstrates how to implement cascading DropDownList editors inside a Syncfusion Essential JS 2 (EJ2) DataGrid using remote data binding in an ASP.NET Core application.
+
+## Overview
+
+The sample shows a real-world editing scenario where the available values of one column’s DropDownList depend on the selection made in another column. Data is fetched dynamically from remote services during Grid editing, ensuring that the dependent dropdown values are always in sync with the selected parent field.
+
+This approach is commonly used in enterprise applications for scenarios such as Country–State selection, Category–Product mapping, or any hierarchical data relationships within tabular editing workflows.
