Blazor DataGrid in Server Side App using CLI
20 May 202524 minutes to read
This article provides a step-by-step instructions to build a Blazor Server App with Syncfusion Blazor DataGrid using the .NET CLI.
Manually creating a project
This section provides a brief explanation on how to manually create a Blazor Server App using CLI.
Prerequisites
Ensure you have the latest version of the .NET Core SDK installed.
To check the installed version, run the following command in a command prompt (Windows), terminal (macOS), or shell (Linux):
dotnet --versionCreate a Blazor Server side project using .NET Core CLI
To create a new Blazor Server application, open your terminal or command prompt and run:
dotnet new blazorserver -o BlazorApp
cd BlazorAppThis command creates new Blazor app project and places it in a new directory called BlazorApp inside your current location. See Create Blazor app topic and dotnet new CLI command topics for more details.
NOTE
If you have installed multiple SDK versions and need any specific framework version (net5.0/netcoreapp3.1) project, then add -f flag along with dotnet new blazorserver comment. Refer here for the available options.
Install Syncfusion Blazor DataGrid and Themes NuGet in the app
To add the Syncfusion.Blazor.Grid NuGet package to your application, use the following command in the command prompt (Windows) or terminal (Linux/macOS). For more details, refer to the Install and manage packages using the dotnet CLI.
dotnet add package Syncfusion.Blazor.Grid --version 29.1.33
dotnet add package Syncfusion.Blazor.Themes --version 29.1.33
dotnet restoreNOTE
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
- Import namespaces:
Open the ~/_Imports.razor file and add the following namespaces:
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Grids- Register the Syncfusion service:
In your ~/Program.cs file, register the Syncfusion Blazor service as shown below:
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
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. Reference the stylesheet and script in the <head> section of your main layout page as shown below:
-
For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.
-
For .NET 7,8,9 and 10 Blazor Server app, include it in the ~/Pages/_Host.cshtml 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.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders"></SfGrid>
@code {
public List<OrderData> Orders { get; set; }
protected override void OnInitialized()
{
Orders = OrderData.GetAllRecords();
}
}public class OrderData
{
public static List<OrderData> Orders = new List<OrderData>();
public OrderData()
{
}
public OrderData( int? OrderID, string CustomerID)
{
this.OrderID = OrderID;
this.CustomerID = CustomerID;
}
public static List<OrderData> GetAllRecords()
{
if (Orders.Count() == 0)
{
int code = 10;
for (int i = 1; i < 2; i++)
{
Orders.Add(new OrderData(1, "ALFKI"));
Orders.Add(new OrderData(2, "ALFKI"));
Orders.Add(new OrderData(3, "ANANTR"));
Orders.Add(new OrderData(4, "ANANTR"));
Orders.Add(new OrderData(5, "ALFKI"));
code += 5;
}
}
return Orders;
}
public int? OrderID { get; set; }
public string CustomerID { get; set; }
}- To build and run the Blazor Server App, use the following command in your terminal or command prompt:
dotnet run
Defining row data
To bind data for the Syncfusion Blazor DataGrid, assign a List<OrderData> (or any other collection that implements IEnumerable<OrderData>) 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.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders"></SfGrid>
@code {
public List<OrderData> Orders { get; set; }
protected override void OnInitialized()
{
Orders = OrderData.GetAllRecords();
}
}public class OrderData
{
public static List<OrderData> Orders = new List<OrderData>();
public OrderData()
{
}
public OrderData( int? OrderID, string CustomerID, DateTime? OrderDate, double? Freight)
{
this.OrderID = OrderID;
this.CustomerID = CustomerID;
this.OrderDate = OrderDate;
this.Freight = Freight;
}
public static List<OrderData> GetAllRecords()
{
if (Orders.Count() == 0)
{
int code = 10;
for (int i = 1; i < 2; i++)
{
Orders.Add(new OrderData(10248, "VINET",new DateTime(1996,07,07), 32.38));
Orders.Add(new OrderData(10249, "TOMSP", new DateTime(1996, 07, 07), 92.38));
Orders.Add(new OrderData(10250, "HANAR", new DateTime(1996, 07, 07), 62.77));
Orders.Add(new OrderData(10251, "VICTE", new DateTime(1996, 07, 07), 12.38));
Orders.Add(new OrderData(10252, "SUPRD", new DateTime(1996, 07, 07), 82.38));
Orders.Add(new OrderData(10253, "CHOPS", new DateTime(1996, 07, 07), 31.31));
Orders.Add(new OrderData(10254, "RICSU", new DateTime(1996, 07, 07), 22.37));
Orders.Add(new OrderData(10255, "WELLI", new DateTime(1996, 07, 07), 44.34));
Orders.Add(new OrderData(10256, "RICSU", new DateTime(1996, 07, 07), 31.33));
code += 5;
}
}
return Orders;
}
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 Syncfusion Blazor DataGrid.
The Grid has an option to define columns using GridColumns. In GridColumn we have properties to customize columns.
Here are the key properties used in the example below:
-
Field : Binds the column to a property on your data model.
-
HeaderText : Sets the displayed column title.
-
TextAlign : Controls the horizontal alignment of cell text. By default, text is left-aligned; set this to
TextAlign.Rightto right-align. -
Format : Applies standard or custom formatting to numeric and date values.
-
Type : Specifies the column data type.
-
Width: Sets the column’s width.
