Getting Started with Blazor DataManager Component in Blazor Web App

15 Apr 202611 minutes to read

This section briefly explains about how to include Syncfusion® Blazor DataManager component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Prerequisites

Create a new Blazor Web App in Visual Studio

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

Prerequisites

Create a new Blazor Web App in Visual Studio Code

Create a Blazor Web App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands in the integrated terminal (Ctrl+`).

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Prerequisites

Install the latest version of .NET SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet --version

Create a Blazor Web App using .NET CLI

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to the Blazor Web App Getting Started documentation.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands:

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

This command creates a new Blazor Web App and places it in a new directory called BlazorWebApp inside your current location. See the Create a Blazor App and dotnet new CLI command topics for more details.

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install Syncfusion® Blazor packages

Install Syncfusion.Blazor.Data and Syncfusion.Blazor.Themes NuGet packages in your project using the NuGet Package Manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), or the integrated terminal in Visual Studio Code (dotnet add package), or the .NET CLI.

Alternatively, run the following commands in the Package Manager Console to achieve the same.

Install-Package Syncfusion.Blazor.Data -Version 33.1.44
Install-Package Syncfusion.Blazor.Themes -Version 33.1.44

If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the client project.

NOTE

All Syncfusion® Blazor packages are available on nuget.org. See the NuGet packages topic for details.

Add import namespaces

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

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

Register Syncfusion® Blazor service

Register the Syncfusion® Blazor service in the Program.cs file of your Blazor Web App.

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

NOTE

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

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 ~/Components/App.razor file.

<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>

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 Syncfusion® Blazor DataManager component

Add the Syncfusion® Blazor DataManager component in the ~/Components/Pages/*.razor file. If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the ~Pages/*.razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto).

NOTE

If the Interactivity Location is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto

The SfDataManager component acts as a data gateway for Syncfusion® Blazor components that support data binding. It enables interaction with local or remote data sources using queries.

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.

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

<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 List<EmployeeData> Employees { get; set; } = 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 Coordinator" },
        new EmployeeData { EmployeeID = 9, Name = "Janet Davolio", Title = "Sales Representative" },
        new EmployeeData { EmployeeID = 10, Name = "Andrew Buchanan", Title = "Sales Representative" }
    };

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

Binding to OData

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

@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 Syncfusion® Blazor DataManager component can be integrated with any Syncfusion® 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.

@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" }
    };
}
Binding DropDownList Item in Blazor DataManager Component

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.

@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; }
    }
}
