Getting Started-Client side using CLI in Blazor DataGrid component

08 Apr 2021 / 6 minutes to read

This article provides a step-by-step introduction to configure Syncfusion Blazor setup, build and run a simple Blazor WebAssembly application using .NET Core CLI.

Note: Starting with version 17.4.0.39 (2019 Volume 4), you need to include a valid license key (either paid or trial key) within your applications. Please refer to this help topic for more information.

Prerequisites

.NET Core SDK 3.1.3

Create a Blazor WebAssembly project using .NET Core CLI

Install the Blazor project templates by using below command line in the command prompt:

dotnet new -i Microsoft.AspNetCore.Components.WebAssembly.Templates::3.2.0-rc1.20223.4

Once project templates installed, run the following command line to create a new Blazor WebAssembly application.

    dotnet new blazorwasm -o WebApplication1
    cd WebApplication1

Importing Syncfusion Blazor component in the application

Now, add Syncfusion.Blazor NuGet package to the new application using the below command line.

    dotnet add package Syncfusion.Blazor -v 18.4.0.42
    dotnet restore

The Syncfusion Blazor package will be included in the newly created project after the installation process is completed.
Open ~/_Imports.razor file and import the Syncfusion.Blazor.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Grids

Open the ~/Program.cs file and register the Syncfusion Blazor Service.

using Syncfusion.Blazor;

namespace WebApplication1
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            ....
            builder.Services.AddSyncfusionBlazor();
            await builder.Build().RunAsync();
        }
    }
}

Add the Syncfusion bootstrap4 theme in the <head> element of the ~/wwwroot/index.html page.

<head>
    ....
    ....
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
</head>

Note: The same theme file can be referred through the CDN version by using https://cdn.syncfusion.com/blazor/18.4.42/styles/bootstrap4.css. To use manual scripts other than the scripts from NuGet package, register the Blazor service in ~/Program.cs file by using true parameter as mentioned below.

using Syncfusion.Blazor;
namespace WebApplication1
{
  public class Program
 {
       public static async Task Main(string[] args)
       {
          ....
          ....
          builder.Services.AddSyncfusionBlazor(true);
          await builder.Build.RunAsync();
       }
   }
}

Add DataGrid Component

To initialize the DataGrid component add the below code to your Index.razor view page which is present under ~/Pages folder. For example, the DataGrid component is added in the ~/Pages/Index.razor page.

<SfGrid >

</SfGrid>

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 lifecycle of the page.

<SfGrid DataSource="@gridData">

</SfGrid>

@code{
public List<OrdersDetails> gridData { get; set; }
protected override void OnInitialized()
{
    gridData = OrdersDetails.GetAllRecords();
}
}

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. In GridColumn component we have properties to customize columns.

Let’s check the properties used here:

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

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

@code{
public List<OrdersDetails> gridData { get; set; }
protected override void OnInitialized()
{
    gridData = OrdersDetails.GetAllRecords();
}
}

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.

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

@code{
public List<OrdersDetails> gridData { get; set; }
protected override void OnInitialized()
{
    gridData = OrdersDetails.GetAllRecords();
}
}

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.

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

@code{
public List<OrdersDetails> gridData { get; set; }
protected override void OnInitialized()
{
    gridData = OrdersDetails.GetAllRecords();
}
}

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.

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

@code{
public List<OrdersDetails> gridData { get; set; }
protected override void OnInitialized()
{
    gridData = OrdersDetails.GetAllRecords();
}
}

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.

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

@code{
public List<OrdersDetails> gridData { get; set; }
