Getting Started with Blazor DataGrid Component in Web App

27 Dec 202414 minutes to read

This section briefly explains about how to include Blazor DataGrid component in your Blazor Web App using Visual Studio.

Prerequisites

System requirements for Blazor components

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion^® Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion^® Blazor Grid and Themes NuGet in the Blazor Web App

To add Blazor DataGrid component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Grid and Syncfusion.Blazor.Themes.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion^® Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.Grid -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion^® Blazor Service

Interactive Render Mode	Description
WebAssembly or Auto	Open ~/_Imports.razor file from the client project.
Server	Open ~/_import.razor file, which is located in the `Components` folder.

Import the Syncfusion.Blazor and Syncfusion.Blazor.Grids namespace.

~/_Imports.razor
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Grids

Now, register the Syncfusion^® Blazor Service in the ~/Program.cs file of your Blazor Web App.

If the Interactive Render Mode is set to WebAssembly or Auto, you need to register the Syncfusion^® Blazor service in both ~/Program.cs files of your Blazor Web App.

If the Interactive Render Mode is set to Server, your project will contain a single ~/Program.cs file. So, you should register the Syncfusion^® Blazor Service only in that ~/Program.cs file.

If Interactive Render Mode as WebAssembly or Auto,

Server(~/_Program.cs)
Client(~/_Program.cs)
...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

If Interactive Render Mode as Server,

~/_Program.cs
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
....
<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion^® Blazor DataGrid component

Add the Syncfusion^® Blazor DataGrid component in .razor file inside the Pages folder. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:

Interactivity location	RenderMode	Code
Per page/component	Auto	@rendermode InteractiveAuto
	WebAssembly	@rendermode InteractiveWebAssembly
	Server	@rendermode InteractiveServer
	None	—

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly or Server, the render mode is configured in the App.razor file by default.

RAZOR

@* desired render mode define here *@
@rendermode InteractiveAuto

RAZOR
<SfGrid DataSource="@Orders" />

@code{
    public List<Order> Orders { get; set; }

    protected override void OnInitialized()
    {
        Orders = Enumerable.Range(1, 5).Select(x => new Order()
        {
            OrderID = 0 + x,
            CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
        }).ToList();
    }

    public class Order
    {
        public int? OrderID { get; set; }
        public string CustomerID { get; set; }

    }
}

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion^® Blazor DataGrid component in your default web browser.

Defining Row Data

To bind data for the DataGrid component, you can assign a IEnumerable object to the DataSource property. The list data source can also be provided as an instance of the DataManager. You can assign the data source through the OnInitialized life cycle of the page.

RAZOR
<SfGrid DataSource="@Orders" />

@code{
    public List<Order> Orders { get; set; }

    protected override void OnInitialized()
    {
        Orders = Enumerable.Range(1, 75).Select(x => new Order()
        {
            OrderID = 1000 + x,
            CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
            Freight = 2.1 * x,
            OrderDate = DateTime.Now.AddDays(-x),
        }).ToList();
    }

    public class Order {
        public int? OrderID { get; set; }
        public string CustomerID { get; set; }
        public DateTime? OrderDate { get; set; }
        public double? Freight { get; set; }
    }
}

Defining columns

The columns are automatically generated when columns declaration is empty or undefined while initializing the datagrid.

The DataGrid has an option to define columns using GridColumns component. To customize column properties, use GridColumns component.

Let’s check the properties used here:

Field is added to map with a property name in IEnumerable object.
HeaderText is added to change the title of columns.
TextAlign is used to change the alignment of columns. By default, columns will be left aligned. To change columns to right align, define TextAlign as Right.
Also, you have used another useful property, Format. Using this, you can format number and date values to standard or custom formats.

RAZOR
<SfGrid DataSource="@Orders">
    <GridColumns>
        <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
        <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
        <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
        <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
    </GridColumns>
</SfGrid>

Enable paging

The paging feature enables users to view the datagrid record in a paged view. It can be enabled by setting the AllowPaging property to true. Pager can be customized using the GridPageSettings component.

RAZOR
<SfGrid DataSource="@Orders" AllowPaging="true">
 <GridPageSettings PageSize="5"></GridPageSettings>
   <GridColumns>
     <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
     <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
     <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
     <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
   </GridColumns>
</SfGrid>

Enable sorting

The sorting feature enables you to order the records. It can be enabled by setting the AllowSorting property as true. Sorting feature can be customized using the GridSortSettings component.

RAZOR
<SfGrid DataSource="@Orders" AllowPaging="true" AllowSorting="true">
 <GridPageSettings PageSize="5"></GridPageSettings>
   <GridColumns>
     <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
     <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
     <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
     <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
   </GridColumns>
</SfGrid>

Enable filtering

The filtering feature enables you to view reduced amount of records based on filter criteria. It can be enabled by setting the AllowFiltering property as true. Filtering feature can be customized using the GridFilterSettings component.

RAZOR
<SfGrid DataSource="@Orders" AllowPaging="true" AllowSorting="true" AllowFiltering="true">
 <GridPageSettings PageSize="5"></GridPageSettings>
   <GridColumns>
     <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
     <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
     <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
     <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
   </GridColumns>
</SfGrid>

Enable grouping

The grouping feature enables you to view the datagrid record in a grouped view. It can be enabled by setting the AllowGrouping property as true. Grouping feature can be customized using the GridGroupSettings component.

RAZOR
<SfGrid DataSource="@Orders" AllowPaging="true" AllowSorting="true" AllowFiltering="true" AllowGrouping="true">
 <GridPageSettings PageSize="5"></GridPageSettings>
   <GridColumns>
     <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
     <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
     <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
     <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
   </GridColumns>
</SfGrid>

Handling exceptions

Exceptions occurred during grid actions can be handled without stopping application. These error messages or exception details can be acquired using the OnActionFailure event.

The argument passed to the OnActionFailure event contains the error details returned from the server.

NOTE

Recommend you to bind OnActionFailure event during your application development phase, this helps you to find any exceptions. You can pass these exception details to our support team to get solution as early as possible.

The following sample code demonstrates notifying user when server-side exception has occurred during data operation,

RAZOR
@using Syncfusion.Blazor.Data

<span class="error">@ErrorDetails</span>
<SfGrid TValue="Order" AllowPaging="true">
    <GridEvents TValue="Order" OnActionFailure="@ActionFailure"></GridEvents>
    <GridPageSettings PageSize="10"></GridPageSettings>
    <SfDataManager Url="https://some.com/invalidUrl" Adaptor="Adaptors.WebApiAdaptor"></SfDataManager>
    <GridColumns>
        <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" IsPrimaryKey="true" TextAlign="TextAlign.Right" Width="120"></GridColumn>
        <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
        <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
        <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
    </GridColumns>
</SfGrid>

<style>
    .error {
        color: red;
    }
</style>

@code{
    public string ErrorDetails = "";
    public class Order
    {
        public int? OrderID { get; set; }
        public string CustomerID { get; set; }
        public DateTime? OrderDate { get; set; }
        public double? Freight { get; set; }
    }

    public void ActionFailure(FailureEventArgs args)
    {
        this.ErrorDetails = "Server exception: 404 Not found";
        StateHasChanged();
    }
}
