dotnet restore

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

Open ~/_Imports.razor file and 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 webAssembly app.

~/Program.cs
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the <head> section of the ~/index.html file.

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

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 Blazor DataGrid

Add the Syncfusion Blazor DataGrid in the ~/Pages/Index.razor file.

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 in your default web browser.

Defining row data

To bind data for the Grid, 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 Grid.

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

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 Syncfusion Blazor DataGrid record in a paged view. It can be enabled by setting the AllowPaging property to true. Pager can be customized using the GridPageSettings.

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.

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.

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 Syncfusion Blazor 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.

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 Syncfusion Blazor DataGrid 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();
    }
}
