Create a new Blazor Server App

• Visual Studio
• Visual Studio Code
• .NET CLI

Create a Blazor Server App by using the Blazor Web App template in Visual Studio via Microsoft Templates or the Blazor Extension.

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

Terminal

dotnet new blazor -o BlazorApp --interactivity Server
cd BlazorApp

Alternatively, create a Blazor Server 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 Server App.

Command Prompt

dotnet new blazor -o BlazorApp --interactivity Server
cd BlazorApp

NOTE

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

Install the required Blazor packages

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

• Visual Studio
• Visual Studio Code
• .NET CLI

1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
2. Search the required NuGet packages (Syncfusion.Blazor.ChartWizard 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.ChartWizard -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.ChartWizard -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.ChartWizard -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Add import namespaces

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

~/_Imports.razor

@using Syncfusion.Blazor
@using Syncfusion.Blazor.ChartWizard

Register the Blazor service

Open the Program.cs file in Blazor Server 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 ~/Components/App.razor file.

App.razor

...
<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 Chart Wizard component

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

NOTE

If the interactivity location is set to Per page/component, define a render mode at the top of the razor file. (For example InteractiveServer). If the Interactivity is set to Global, the render mode is automatically configured in the App.razor file by default.

Home.razor

@rendermode InteractiveServer

<SfChartWizard Height="600px">

</SfChartWizard>

Run the application

• Visual Studio
• Visual Studio Code
• .NET CLI

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor Chart Wizard 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

Populate Blazor Chart Wizard data

To bind data for the chart wizard component, you can assign an IEnumerable object to the DataSource property.

Home.razor

public class OlympicsData
{
    public string? Country { get; set; }
    public string? CountryCode { get; set; }
    public int Gold { get; set; }
    public int Silver { get; set; }
    public int Bronze { get; set; }
}

private readonly List<OlympicsData> OlympicsDataSource = new()
{
    new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
    new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
    new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
    new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
    new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
    new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
    new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
    new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
    new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
    new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
};

Now, populate the categories and chartSeries collections with the appropriate data defining the chart’s categories and series. Then, assign these values to the CategoryFields and SeriesFields properties of the ChartSettings, respectively.

NOTE

The default series type is Line. Use the SeriesType property to change the series type.

Home.razor

@using Syncfusion.Blazor.ChartWizard

<div class="control-section">
    <SfChartWizard>
        <ChartSettings DataSource="@OlympicsDataSource"
                       CategoryFields="@categories"
                       SeriesType="ChartWizardSeriesType.Column"
                       SeriesFields="@chartSeries">
        </ChartSettings>
    </SfChartWizard>
</div>

@code 
{
    private readonly List<string> chartSeries = new() { "Gold", "Silver", "Bronze" };
    private readonly List<string> categories = new() { "Country", "CountryCode" };

    public class OlympicsData
    {
        public string? Country { get; set; }
        public string? CountryCode { get; set; }
        public int Gold { get; set; }
        public int Silver { get; set; }
        public int Bronze { get; set; }
    }

    private readonly List<OlympicsData> OlympicsDataSource = new()
    {
        new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
        new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
        new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
        new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
        new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
        new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
        new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
        new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
        new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
        new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
    };
}

Prerequisites

In order to apply same theme update for the overall Chart Wizard UI, include the same theme stylesheet (this can be accessed from NuGet through Static Web Assets) in the <head> tag in the ~/Components/App.razor file as shown below:

App.razor

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/material3.css" rel="stylesheet" />
</head>

The Theme property is used to specify the visual theme applied to the chart.

Home.razor

@using Syncfusion.Blazor.ChartWizard

<div class="control-section">
    <SfChartWizard Theme="Theme.Material3">
        <ChartSettings DataSource="@OlympicsDataSource"
                       CategoryFields="@categories"
                       SeriesType="ChartWizardSeriesType.Bar"
                       SeriesFields="@chartSeries">
        </ChartSettings>
    </SfChartWizard>
</div>

@code 
{
    private readonly List<string> chartSeries = new() { "Gold", "Silver", "Bronze" };
    private readonly List<string> categories = new() { "Country", "CountryCode" };

    public class OlympicsData
    {
        public string? Country { get; set; }
        public string? CountryCode { get; set; }
        public int Gold { get; set; }
        public int Silver { get; set; }
        public int Bronze { get; set; }
    }

    private readonly List<OlympicsData> OlympicsDataSource = new()
    {
        new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
        new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
        new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
        new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
        new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
        new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
        new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
        new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
        new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
        new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
    };
}
