Getting Started with Essential JS 2 for Blazor client-side in .NET Core CLI

This article provides a step-by-step introduction to configure Essential JS 2 for Blazor setup, build and run a simple Blazor client-side web application using .Net Core CLI.

Prerequisites

Create a Blazor client-side project using .NET Core CLI

Step 1: Install the Blazor project templates by using below command line in the command prompt:

  dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview6.19307.2

Step 2: Once project templates installed, run the following command line to create a new Blazor client-side application.

  dotnet new blazor -o WebApplication1

  cd WebApplication1

Adding Syncfusion Packages

Step 1: Now, add Syncfusion.Blazor NuGet package to the new application using below command line.

  dotnet add package Syncfusion.Blazor

  dotnet restore

Step 2: The Syncfusion Blazor package will be included in the newly created project after the installation process is completed

Step 3: Open ~/_Imports.razor file and import the Syncfusion.Blazor.

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

Adding Scripts and CSS reference

Add the client-side resource through CDN or local npm package in the <head> element of the ~/Pages/index.html page.

<head>
    ....
    ....
    <link href="https://cdn.syncfusion.com/blazor/styles/fabric.css" rel="stylesheet" />
</head>

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 FilterSettings property.

<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; }
    protected override void OnInitialized()
    {
        gridData = OrdersDetails.GetAllRecords();
    }
}
