In this documentation, two approaches will be examined to connect a SQLite Server database to a Grid. Both the approaches have capability to handle data and CRUD operations with built-in methods as well as can be customized as per your own. + +**1. Using UrlAdaptor** + +The [UrlAdaptor](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/url-adaptor) serves as the base adaptor for facilitating communication between remote data services and an UI component. It enables the remote binding of data to the Syncfusion ASP.NET MVC Grid by connecting to an existing pre-configured API service linked to the Microsoft SQL Server database. While the Grid supports various adaptors to fulfill this requirement, including [Web API](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/web-api-adaptor), [ODataV4](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/odatav4-adaptor), [UrlAdaptor](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/url-adaptor), [Web Method](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/web-method-adaptor), and `GraphQL`, the `UrlAdaptor` is particularly useful for the scenarios where a custom API service with unique logic for handling data and CRUD operations is in place. This approach allows for custom handling of data and CRUD operations, and the resultant data returned in the `result` and `count` format for display in the Grid. + +**2. Using CustomAdaptor** + +The [CustomAdaptor](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/connecting-to-adaptors/custom-adaptor) serves as a mediator between the UI component and the database for data binding. While the data source from the database can be directly bound to the Syncfusion ASP.NET MVC Grid locally using the `DataSource` property, the `CustomAdaptor` approach is preferred as it allows for customization of both data operations and CRUD operations according to specific requirements. In this approach, for every action in the Grid, a corresponding request with action details is sent to the `CustomAdaptor`. The Grid provides predefined methods to perform data operations such as **searching**, **filtering**, **sorting**, **aggregation**, **paging** and **grouping**. Alternatively, your own custom methods can be employed to execute operations and return the data in the `result` and `count` format for displaying in the Grid. Additionally, for CRUD operations, predefined methods can be overridden to provide custom functionality. Further details on this can be found in the latter part of the documentation. + +## Binding data from SQLite Server using an API service + +This section describes step by step process how to retrieve data from a SQLite Server using an API service and bind it to the Grid. + +### Creating an API service + +**1.** Open Visual Studio and create an ASP.NET MVC project named **Grid_SQLite**. To create an ASP.NET MVC application, follow the documentation [link](https://learn.microsoft.com/en-us/aspnet/mvc/overview/getting-started/introduction/getting-started#create-your-first-app) for detailed steps. + +**2.** To connect a SQLite Server database using the SQLite driver in your application, you need to install the [Microsoft.Data.Sqlite](https://www.nuget.org/packages/Microsoft.Data.Sqlite/) NuGet package. To add **Microsoft.Data.Sqlite** in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install it. + +**3.** Create an API controller (aka, GridController.cs) file under **Controllers** folder that helps to establish data communication with the Grid. + +**4.** In an API controller (aka, GridController), connect to SQLite Server. In the **GetOrderData()** method **SqliteConnection** helps to connect the SQLite Server database. Next, the **SqliteCommand** is used to retrieve the desired collection from the database. Then populate the data collection from the **SqliteCommand** into a list using the **Read** method of **SqliteDataReader** as shown in the following code snippet. + +{% tabs %} +{% highlight cs tabtitle="GridController.cs" %} + +using Microsoft.Data.Sqlite; +using Syncfusion.EJ2.Base; +using System.Collections.Generic; +using System.ComponentModel.DataAnnotations; +using System.Linq; +using System.Web.Mvc; + +namespace Grid_Sqlite.Controllers +{ + public class GridController : Controller + { + private readonly string ConnectionString = ""; + + /// + /// Processes the DataManager request to perform searching, filtering, sorting, and paging operations. + /// + /// Contains the details of the data operation requested. + /// Returns a JSON object along with the total record count. + [HttpPost] + public object UrlDataSource() + { + // Retrieve data from the database. + IQueryable dataSource = GetOrderData().AsQueryable(); + + // Get the total count of records. + int totalRecordsCount = dataSource.Count(); + + // Return the data and total record count as a JSON response. + return Ok(new { result = dataSource, count = totalRecordsCount }); + } + + /// + /// Retrieves the order data from the database. + /// + /// Returns a list of orders fetched from the database. + [HttpGet] + public List GetOrderData() + { + // SQL query to fetch all records from the Orders table and sort them by OrderID. + string queryStr = "SELECT * FROM Orders ORDER BY OrderID."; + + // Create a list to store retrieved orders from the database. + List dataSource = new List(); + + // Establish a connection to the SQLite database using the provided connection string. + using (SqliteConnection connection = new SqliteConnection(ConnectionString)) + { + // Open the database connection to enable SQL queries. + connection.Open(); + + // Create a command to execute the SQL query. + using (SqliteCommand command = new SqliteCommand(queryStr, connection)) + { + // Execute the command and retrieve data using SqliteDataReader. + using (SqliteDataReader reader = command.ExecuteReader()) + { + while (reader.Read()) + { + Orders order = new Orders + { + OrderID = reader.GetInt32(reader.GetOrdinal("OrderID")), + CustomerID = reader.GetString(reader.GetOrdinal("CustomerID")), + EmployeeID = reader.GetInt32(reader.GetOrdinal("EmployeeID")), + ShipCity = reader.GetString(reader.GetOrdinal("ShipCity")), + Freight = reader.GetDecimal(reader.GetOrdinal("Freight")) + }; + dataSource.Add(order); + } + } + } + } + return dataSource; + } + + /// Represents an order entity with relevant fields. + public class Orders + { + [Key] + public int?
