ODataV4Adaptor in Syncfusion Angular Grid Component

17 Sep 202524 minutes to read

The ODataV4Adaptor in the Syncfusion Angular Grid Component enables seamless integration with OData v4 services, providing efficient data fetching and manipulation capabilities. This guide provides detailed instructions on binding data and performing CRUD (Create, Read, Update, Delete) actions using the ODataV4Adaptor in the Syncfusion Angular Grid Component.

Creating an OData service

To configure a server with Syncfusion Angular Grid, follow these steps:

1. Project Creation:

Open Visual Studio and create an Angular and ASP.NET Core project named ODataV4Adaptor. To create an Angular and ASP.NET Core application, follow the documentation link for detailed steps.

2. Install NuGet Packages

Using the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), install the Microsoft.AspNetCore.OData NuGet package.

3. Model Class Creation:

Create a model class named OrdersDetails.cs in the server-side Models folder to represent the order data.

OrdersDetails.cs
using System.ComponentModel.DataAnnotations;

namespace ODataV4Adaptor.Server.Models
{
 public class OrdersDetails
    {
        public static List<OrdersDetails> order = new List<OrdersDetails>();
        public OrdersDetails()
        {

        }
        public OrdersDetails(
        int OrderID, string CustomerId, int EmployeeId, string ShipCountry)
        {
            this.OrderID = OrderID;
            this.CustomerID = CustomerId;
            this.EmployeeID = EmployeeId;
            this.ShipCountry = ShipCountry;
        }

        public static List<OrdersDetails> GetAllRecords()
        {
            if (order.Count() == 0)
            {
                int code = 10000;
                for (int i = 1; i < 10; i++)
                {
                    order.Add(new OrdersDetails(code + 1, "ALFKI", i + 0,  "Denmark"));
                    order.Add(new OrdersDetails(code + 2, "ANATR", i + 2, "Brazil"));
                    order.Add(new OrdersDetails(code + 3, "ANTON", i + 1, "Germany"));
                    order.Add(new OrdersDetails(code + 4, "BLONP", i + 3, "Austria"));
                    order.Add(new OrdersDetails(code + 5, "BOLID", i + 4, "Switzerland"));
                    code += 5;
                }
            }
            return order;
        }
        [Key]
        public int? OrderID { get; set; }
        public string? CustomerID { get; set; }
        public int? EmployeeID { get; set; }
        public string? ShipCountry { get; set; }
    }
}

4. Build the Entity Data Model

To construct the Entity Data Model for the OData service, utilize the ODataConventionModelBuilder to define the model structure. Create an instance of the ODataConventionModelBuilder, then register the entity set Orders using the EntitySet<T> method, where OrdersDetails represents the CLR type containing order details.

// Create an ODataConventionModelBuilder to build the OData model
var modelBuilder = new ODataConventionModelBuilder();

// Register the "Orders" entity set with the OData model builder
modelBuilder.EntitySet<OrdersDetails>("Orders");

5. Register the OData Services

Once the Entity Data Model is built, register the OData services in the ASP.NET Core application. Here’s the configuration:

// Add controllers with OData support to the service collection
builder.Services.AddControllers().AddOData(
    options => options
        .Count()
        .AddRouteComponents("odata", modelBuilder.GetEdmModel()));

6. Add controllers

Add controllers to expose the OData endpoints. Here’s an example:

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.OData.Query;
using ODataV4Adaptor.Server.Models;

namespace ODataV4Adaptor.Server.Controllers
{
    [Route("[controller]")]
    [ApiController]
    public class OrdersController : ControllerBase
    {
        /// <summary>
        /// Retrieves all orders.
        /// </summary>
        /// <returns>The collection of orders.</returns>
        [HttpGet]
        [EnableQuery]
        public IActionResult Get()
        {
            var data = OrdersDetails.GetAllRecords().AsQueryable();
            return Ok(data);
        }
    }
}

7. Run the Application:

Run the application in Visual Studio. The application will be accessible on a URL like https://localhost:xxxx.

After running the application, verify that the server-side API controller successfully returns the order data at the URL (https://localhost:xxxx/odata/Orders). Here xxxx represents the port number.

Connecting Syncfusion Angular Grid to an OData service

To integrate the Syncfusion Grid component into the Angular and ASP.NET Core project using Visual Studio, follow these steps:

Step 1: Install Syncfusion Package

Open the terminal in the project’s client folder and install the required Syncfusion packages using npm:

npm install @syncfusion/ej2-angular-grids --save
npm install @syncfusion/ej2-data --save

Step 2: Import Grid Module

In the app.module.ts file, import the GridModule from the @syncfusion/ej2-angular-grids package:

app.module.ts
import { GridModule } from '@syncfusion/ej2-angular-grids';

@NgModule({
  imports: [
    // Other imports...
    GridModule,
  ],
})
export class AppModule { }

Step 3: Adding CSS reference

Include the necessary CSS files in the styles.css file to style the Syncfusion Angular component:

styles.css
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-angular-grids/styles/material.css';

Step 4: Adding Syncfusion Component

In the component file (e.g., app.component.ts), import DataManager and ODataV4Adaptor from @syncfusion/ej2-data. Create a DataManager instance specifying the URL of the API endpoint (https:localhost:xxxx/odata/Orders) using the url property and set the adaptor to ODataV4Adaptor.

app.component.ts
app.component.html
import { Component, ViewChild } from '@angular/core';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';
import { GridComponent } from '@syncfusion/ej2-angular-grids';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})
export class AppComponent {
  public data?: DataManager;

  @ViewChild('grid')
  public grid?: GridComponent;

  ngOnInit(): void {
    this.data = new DataManager({
      url:'https://localhost:xxxx/odata/Orders', // Here xxxx represents the port number
      adaptor: new ODataV4Adaptor()
    });
  }
}
<ejs-grid #grid [dataSource]='data'>
  <e-columns>
    <e-column field='OrderID' headerText='Order ID' width='120' textAlign='Right' isPrimaryKey="true"></e-column>
    <e-column field='CustomerID' headerText='Customer ID' width='160'></e-column>
    <e-column field='EmployeeID' headerText='Employee ID' width='150'></e-column>
    <e-column field='ShipCountry' headerText='Ship Country' width='150'></e-column>
  </e-columns>
</ejs-grid>

Replace https://localhost:xxxx/odata/Orders with the actual URL of the API endpoint that provides the data in a consumable format (e.g., JSON).

Run the application in Visual Studio. The application will be accessible on a URL like https://localhost:xxxx.

Ensure the API service is configured to handle CORS (Cross-Origin Resource Sharing) if necessary.

  [program.cs]
  builder.Services.AddCors(options =>
  {
    options.AddDefaultPolicy(builder =>
    {
      builder.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader();
    });
  });
  var app = builder.Build();
  app.UseCors();

Handling searching operation

To enable search operations in the web application using OData, configure the OData support in the service collection. This involves adding the Filter method within the OData setup, allowing data to be filtered based on specified criteria. Once enabled, clients can utilize the $filter query option in requests to search for specific data entries.

program.cs
app.component.ts
app.component.html
app.module.ts
// Create a new instance of the web application builder
var builder = WebApplication.CreateBuilder(args);

// Create an ODataConventionModelBuilder to build the OData model
var modelBuilder = new ODataConventionModelBuilder();

// Register the "Orders" entity set with the OData model builder
modelBuilder.EntitySet<OrdersDetails>("Orders");

// Add services to the container.

// Add controllers with OData support to the service collection
builder.Services.AddControllers().AddOData(
    options => options
        .Count()
        .Filter() //searching
        .AddRouteComponents("odata", modelBuilder.GetEdmModel()));
import { Component, ViewChild } from '@angular/core';
import { GridComponent } from '@syncfusion/ej2-angular-grids';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  @ViewChild('grid')
  public grid?: GridComponent;
  public data?: DataManager;
  public toolbar?: ToolbarItems[];

  ngOnInit(): void {
    this.data = new DataManager({
      url: 'https://localhost:xxxx/odata/Orders',
      adaptor: new ODataV4Adaptor()
    });
  }
  this.toolbar = ['Search'];
}
<ejs-grid #grid [dataSource]='data' [toolbar]='toolbar'>
  <e-columns>
    <e-column field='OrderID' headerText='Order ID' isPrimaryKey=true width='150'></e-column>
    <e-column field='CustomerID' headerText='Customer Name' width='150'></e-column>
    <e-column field='EmployeeID' headerText='Employee ID' width='150'></e-column>
    <e-column field='ShipCountry' headerText='Ship Country' width='150'></e-column>
  </e-columns>
</ejs-grid>

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { GridModule, ToolbarService } from '@syncfusion/ej2-angular-grids';

@NgModule({

Handling sorting operation

To enable sorting operations in the web application using OData, configure the OData support in the service collection. This involves adding the OrderBy method within the OData setup, allowing data to be sorted based on specified criteria. Once enabled, clients can utilize the $orderby query option in requests to sort data entries according to desired attributes.

program.cs
app.component.ts
app.component.html
app.module.ts
// Create a new instance of the web application builder
var builder = WebApplication.CreateBuilder(args);

// Create an ODataConventionModelBuilder to build the OData model
var modelBuilder = new ODataConventionModelBuilder();

// Register the "Orders" entity set with the OData model builder
modelBuilder.EntitySet<OrdersDetails>("Orders");

// Add services to the container.

// Add controllers with OData support to the service collection
builder.Services.AddControllers().AddOData(
    options => options
        .Count()
        .OrderBy() // sorting
        .AddRouteComponents("odata", modelBuilder.GetEdmModel()));
import { Component, ViewChild } from '@angular/core';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';
import { GridComponent } from '@syncfusion/ej2-angular-grids';

@Component({

Handling paging operation

To implement paging operations in the web application using OData, utilize the SetMaxTop method within the OData setup to limit the maximum number of records that can be returned per request. While configuring the maximum limit, clients can utilize the $skip and $top query options in requests to specify the number of records to skip and the number of records to take, respectively.

Program.cs
app.component.ts
app.component.html
app.module.ts
// Create a new instance of the web application builder
var builder = WebApplication.CreateBuilder(args);

// Create an ODataConventionModelBuilder to build the OData model
var modelBuilder = new ODataConventionModelBuilder();

// Register the "Orders" entity set with the OData model builder
modelBuilder.EntitySet<OrdersDetails>("Orders");

// Add services to the container.

// Add controllers with OData support to the service collection

var recordCount= OrdersDetails.GetAllRecords().Count;

builder.Services.AddControllers().AddOData(
    options => options
    .Count()
    .SetMaxTop(recordCount)
    .AddRouteComponents(
        "odata",
        modelBuilder.GetEdmModel()));
import { Component, ViewChild } from '@angular/core';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';

Handling CRUD operations

To manage CRUD (Create, Read, Update, Delete) operations using the ODataV4Adaptor, follow the provided guide for configuring the Syncfusion Grid for editing and utilize the sample implementation of the OrdersController in the server application. This controller handles HTTP requests for CRUD operations such as GET, POST, PATCH, and DELETE.

To enable CRUD operations in the Syncfusion Grid component within an Angular application, follow these steps:

app.component.ts
app.component.html
app.module.ts
import { Component, ViewChild } from '@angular/core';
import { GridComponent, ToolbarItems, EditSettingsModel } from '@syncfusion/ej2-angular-grids';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  @ViewChild('grid')
  public grid?: GridComponent;
  public data?: DataManager;
  public editSettings?: EditSettingsModel;
  public toolbar?: ToolbarItems[];

  ngOnInit(): void {
    this.data = new DataManager({
      url: 'https://localhost:xxxx/odata/Orders', // xxxx denotes port number
      adaptor: new ODataV4Adaptor()
    });

    this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Normal' };
    this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel', 'Search'];
  }
}
<ejs-grid #grid [dataSource]='data' [editSettings]="editSettings" [toolbar]="toolbar">
  <e-columns>
    <e-column field='OrderID' headerText='Order ID' isPrimaryKey=true width='150'></e-column>
    <e-column field='CustomerID' headerText='Customer Name' width='150'></e-column>
    <e-column field='EmployeeID' headerText='Employee ID' width='150'></e-column>
    <e-column field='ShipCountry' headerText='Ship Country' width='150'></e-column>
  </e-columns>
</ejs-grid>
import { HttpClientModule } from '@angular/common/http';
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { EditService, GridModule, ToolbarService } from '@syncfusion/ej2-angular-grids';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule, HttpClientModule,
    AppRoutingModule,
    GridModule
  ],
  providers: [EditService, ToolbarService],
  bootstrap: [AppComponent]
})
export class AppModule { }

Normal/Inline editing is the default edit mode for the Grid component. To enable CRUD operations, ensure that the isPrimaryKey property is set to true for a specific Grid column, ensuring that its value is unique.

Insert Record

To insert a new record into the Syncfusion Grid, utilize the HttpPost method in the server application. Below is a sample implementation of inserting a record using the OrdersController:

/// <summary>
/// Inserts a new order to the collection.
/// </summary>
/// <param name="addRecord">The order to be inserted.</param>
/// <returns>It returns the newly inserted record detail.</returns>
[HttpPost]
[EnableQuery]
public IActionResult Post([FromBody] OrdersDetails addRecord)
{
    if (addRecord == null)
    {
      return BadRequest("Null order");
    }
    OrdersDetails.GetAllRecords().Insert(0, addRecord);
    return Json(addRecord);
}

ODataV4Adaptor-Insert-record

Update Record

Updating a record in the Syncfusion Grid can be achieved by utilizing the HttpPatch method in the controller. Here’s a sample implementation of updating a record:

/// <summary>
/// Updates an existing order.
/// </summary>
/// <param name="key">The ID of the order to update.</param>
/// <param name="updateRecord">The updated order details.</param>
/// <returns>It returns the updated order details.</returns>
[HttpPatch("{key}")]
public IActionResult Patch(int key, [FromBody] OrdersDetails updateRecord)
{
    if (updateRecord == null)
    {
        return BadRequest("No records");
    }
    var existingOrder = OrdersDetails.GetAllRecords().FirstOrDefault(order => order.OrderID == key);
    if (existingOrder != null)
    {
        // If the order exists, update its properties
        existingOrder.CustomerID = updateRecord.CustomerID ?? existingOrder.CustomerID;
        existingOrder.EmployeeID = updateRecord.EmployeeID ?? existingOrder.EmployeeID;
        existingOrder.ShipCountry = updateRecord.ShipCountry ?? existingOrder.ShipCountry;
    }
    return Json(updateRecord);
}

ODataV4Adaptor-Update-record

Delete Record

To delete a record from the Syncfusion Grid, utilize the HttpDelete method in the controller. Below is a sample implementation:

/// <summary>
/// Deletes an order.
/// </summary>
/// <param name="key">The ID of the order to delete.</param>
/// <returns>It returns the deleted record detail</returns>
[HttpDelete("{key}")]
public IActionResult Delete(int key)
{
    var deleteRecord = OrdersDetails.GetAllRecords().FirstOrDefault(order => order.OrderID == key);
    if (deleteRecord != null)
    {
        OrdersDetails.GetAllRecords().Remove(deleteRecord);
    }
    return Json(deleteRecord);
}

You can find the complete sample for the ODataV4Adaptor in GitHub link.

OData with custom URL

The Syncfusion ODataV4 adaptor extends support for calling customized URLs to accommodate data retrieval and CRUD actions as per application requirements. However, when utilizing a custom URL with the ODataV4 adaptor, it’s essential to modify the routing configurations in the application’s route configuration file to align with the custom URL. Custom URLs can be invoked using the following methods in the DataManager.

Configuring Custom URLs

To work with custom URLs for CRUD operations in the Syncfusion Grid, use the following properties:

insertUrl: Specifies the custom URL for inserting new records.
removeUrl: Specifies the custom URL for deleting records.
updateUrl: Specifies the custom URL for updating records.
batchUrl: Specifies the custom URL for batch editing operations.

Ensure that the routing configurations on the server-side are properly updated to handle these custom URLs.

The following code example describes the above behavior.

app.component.ts
import { Component, ViewChild } from '@angular/core';
import { GridComponent, ToolbarItems, EditSettingsModel } from '@syncfusion/ej2-angular-grids';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  @ViewChild('grid')
  public grid?: GridComponent;
  public data?: DataManager;
  public editSettings?: EditSettingsModel;
  public toolbar?: ToolbarItems[];

  ngOnInit(): void {
    this.data = new DataManager({
      url: 'https://localhost:xxxx/odata/Orders', // xxxx denotes port number
      updateUrl: 'https://localhost:xxxx/odata/Orders/Update', // custom URL to update the record
      insertUrl: 'https://localhost:xxxx/odata/Orders/Insert', // custom URL to insert new record
      removeUrl: 'https://localhost:xxxx/odata/Orders/Delete', // custom URL to delete the record
      adaptor: new ODataV4Adaptor()
    });

    this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Normal' };
    this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel', 'Search'];
  }

For batch editing, specify a custom batch URL as follows:

app.component.ts
import { Component, ViewChild } from '@angular/core';
import { GridComponent, ToolbarItems, EditSettingsModel } from '@syncfusion/ej2-angular-grids';
import { DataManager, ODataV4Adaptor } from '@syncfusion/ej2-data';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  @ViewChild('grid')
  public grid?: GridComponent;
  public data?: DataManager;
  public editSettings?: EditSettingsModel;
  public toolbar?: ToolbarItems[];

  ngOnInit(): void {
    this.data = new DataManager({
      url: 'https://localhost:xxxx/odata/Orders', // xxxx denotes port number
      batchUrl: 'https://localhost:xxxx/odata/Orders/BatchUpdate', // custom URL for batch update
      adaptor: new ODataV4Adaptor()
    });

    this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Batch' };
    this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel', 'Search'];
  }
}
