Getting Started with Blazor DataManager in Blazor WASM App

9 Jul 202610 minutes to read

This section explains how to include the Blazor DataManager component in a Blazor WebAssembly App using Visual Studio, Visual Studio Code, and the .NET CLI.

Create a new Blazor WebAssembly (Standalone) App

Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Blazor Extension.

Run the following command to create a new Blazor WebAssembly App.

Terminal

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Alternatively, create a Blazor WebAssembly App using Visual Studio Code via Microsoft Templates or the Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor WebAssembly App.

Command Prompt

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Install the required Blazor packages

Install the Syncfusion.Blazor.Data, Syncfusion.Blazor.Grid, and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.

Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
Search the required NuGet packages (Syncfusion.Blazor.Data, Syncfusion.Blazor.Grid, and Syncfusion.Blazor.Themes) and install them.

Alternatively, you can install the same packages using the Package Manager Console with the following commands.

Package Manager Console

Install-Package Syncfusion.Blazor.Data -Version 34.1.29
Install-Package Syncfusion.Blazor.Grid -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29

Open the terminal and run the following commands.

Terminal

dotnet add package Syncfusion.Blazor.Data -v 34.1.29
dotnet add package Syncfusion.Blazor.Grid -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Open the command prompt and run the following commands.

Command Prompt

dotnet add package Syncfusion.Blazor.Data -v 34.1.29
dotnet add package Syncfusion.Blazor.Grid -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor, Syncfusion.Blazor.Grids, and Syncfusion.Blazor.Data namespaces.

~/_Imports.razor

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

Register the Blazor service

Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.

Program.cs
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

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 ~wwwroot/index.html file.

index.html
...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor DataManager component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor DataManager component inside the razor file.

The SfDataManager component is designed to work with data-bound components that support data operations. It serves as a gateway for both local and remote data, enabling interaction with the data source based on the configured query.

Binding to JSON data

Local JSON data can be bound to the DataGrid component by assigning a collection of objects to the Json property of the SfDataManager component.

Home.razor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.Grids

<SfGrid TValue="EmployeeData" ID="Grid">
    <SfDataManager Json="@Employees"></SfDataManager>
    <GridColumns>
        <GridColumn Field="@nameof(EmployeeData.EmployeeID)" TextAlign="TextAlign.Center" HeaderText="Employee ID" Width="120"></GridColumn>
        <GridColumn Field="@nameof(EmployeeData.Name)" HeaderText="First Name" Width="130"></GridColumn>
        <GridColumn Field="@nameof(EmployeeData.Title)" HeaderText="Title" Width="120"></GridColumn>
    </GridColumns>
</SfGrid>

@code 
{
    public class EmployeeData
    {
        public int EmployeeID { get; set; }
        public string Name { get; set; }
        public string Title { get; set; }
    }

    public List<EmployeeData> Employees = new()
    {
        new EmployeeData { EmployeeID = 1, Name = "Nancy Fuller", Title = "Vice President" },
        new EmployeeData { EmployeeID = 2, Name = "Steven Buchanan", Title = "Sales Manager" },
        new EmployeeData { EmployeeID = 3, Name = "Janet Leverling", Title = "Sales Representative" },
        new EmployeeData { EmployeeID = 4, Name = "Andrew Davolio", Title = "Inside Sales Coordinator" },
        new EmployeeData { EmployeeID = 5, Name = "Steven Peacock", Title = "Inside Sales Coordinator" },
        new EmployeeData { EmployeeID = 6, Name = "Janet Buchanan", Title = "Sales Representative" },
        new EmployeeData { EmployeeID = 7, Name = "Andrew Fuller", Title = "Inside Sales Coordinator" },
        new EmployeeData { EmployeeID = 8, Name = "Steven Davolio", Title = "Inside Sales Coordinato" },
        new EmployeeData { EmployeeID = 9, Name = "Janet Davolio", Title = "Sales Representative" },
        new EmployeeData { EmployeeID = 10, Name = "Andrew Buchanan", Title = "Sales Representative" }
    };
}

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor DataManager component will render in your default web browser.

Open the terminal and run the following command.

Terminal

dotnet run

Open the command prompt and run the following command.

Command Prompt

dotnet run

Binding to OData

Remote data can be bound to the DataGrid component by configuring the Url property and specifying the appropriate adaptor using the Adaptor property of the SfDataManager component.

Home.razor
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.Grids

<SfGrid TValue="Order" ID="Grid" AllowPaging="true">
    <SfDataManager Url="https://services.odata.org/Northwind/Northwind.svc/Orders"
                   Adaptor="Adaptors.ODataAdaptor">
    </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>

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

Component binding

The Blazor DataManager component can be integrated with any data-bound component to manage local or remote data operations.

This configuration demonstrates how the DataManager is bound to the SfDropDownList component to enable consistent interaction with local or remote data sources.

Local data binding

Local data can be bound to components such as SfDropDownList by assigning a collection of objects to the Json property of the SfDataManager component.

Home.razor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.DropDowns

<SfDropDownList Placeholder="e.g. Australia" TItem="Country" TValue="string">
    <SfDataManager Json="@Countries"></SfDataManager>
    <DropDownListFieldSettings Value="Name"></DropDownListFieldSettings>
</SfDropDownList>

@code 
{
    public class Country
    {
        public string? Name { get; set; }
        public string? Code { get; set; }
    }

    public List<Country> Countries = new()
    {
        new Country { Name = "Australia", Code = "AU" },
        new Country { Name = "Bermuda", Code = "BM" },
        new Country { Name = "Canada", Code = "CA" },
        new Country { Name = "Cameroon", Code = "CM" }
    };
}

Remote data binding

Remote data can be bound by setting the Url property and specifying the appropriate adaptor using the Adaptor property of the SfDataManager component.

Home.razor
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.DropDowns

<SfDropDownList Placeholder="Name" TItem="Contact" TValue="Contact">
    <SfDataManager Url="https://services.odata.org/V4/Northwind/Northwind.svc/Customers" Adaptor="Adaptors.ODataV4Adaptor"></SfDataManager>
    <DropDownListFieldSettings Value="CustomerID" Text="ContactName"></DropDownListFieldSettings>
</SfDropDownList>

@code 
{
    public class Contact
    {
        public string? ContactName { get; set; }
        public string? CustomerID { get; set; }
    }
}
