This section briefly explains how to include the Blazor Range Selector component in a Blazor WebAssembly App using Visual Studio, Visual Studio Code, and the .NET CLI.
Create a new Blazor WASM App
Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Blazor Extension. For detailed instructions, refer to the Blazor WebAssembly App Getting Started documentation.
Run the following command to create a new Blazor WebAssembly App.
dotnet new blazorwasm -o BlazorApp
cd BlazorAppAlternatively, create a Blazor WebAssembly App using Visual Studio Code via Microsoft Templates, the Blazor Extension, or the C# Dev Kit extension.
Run the following command to create a new Blazor WebAssembly App.
dotnet new blazorwasm -o BlazorApp
cd BlazorAppInstall the required Blazor packages
Install Syncfusion.Blazor.RangeNavigator 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.RangeNavigatorandSyncfusion.Blazor.Themes) and install them.
Alternatively, you can install the same packages using the Package Manager Console with the following commands.
Install-Package Syncfusion.Blazor.RangeNavigator -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29Open the terminal and run the following commands.
dotnet add package Syncfusion.Blazor.RangeNavigator -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29Open the command prompt and run the following commands.
dotnet add package Syncfusion.Blazor.RangeNavigator -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29Add import namespaces
After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.ChartsRegister the Blazor service
Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.
....
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.
...
<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 Range Selector component
Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor Range Selector component inside the razor file.
<SfRangeNavigator>
</SfRangeNavigator>Populate Blazor Range Navigator with Data
To bind the data for the Range Navigator component, assign an IEnumerable object to the DataSource property. It can also be provided as an instance of the DataManager.
@code {
public class StockPrice
{
public DateTime Date { get; set; }
public double Close { get; set; }
}
public List<StockPrice> StockDetails = new List<StockPrice>
{
new StockPrice { Date = new DateTime(2005, 01, 01), Close = 21 },
new StockPrice { Date = new DateTime(2006, 01, 01), Close = 24 },
new StockPrice { Date = new DateTime(2007, 01, 01), Close = 36 },
new StockPrice { Date = new DateTime(2008, 01, 01), Close = 38 },
new StockPrice { Date = new DateTime(2009, 01, 01), Close = 54 },
new StockPrice { Date = new DateTime(2010, 01, 01), Close = 57 },
new StockPrice { Date = new DateTime(2011, 01, 01), Close = 62 }
};
}Now map Date and Close fields from the data source to XName and YName properties of the RangeNavigatorSeries and then set the StockDetails to DataSource property.
<SfRangeNavigator ValueType="RangeValueType.DateTime" IntervalType="RangeIntervalType.Years" LabelFormat="yyyy">
<RangeNavigatorSeriesCollection>
<RangeNavigatorSeries DataSource="@StockDetails" XName="Date" Type="RangeNavigatorType.Area" YName="Close"></RangeNavigatorSeries>
</RangeNavigatorSeriesCollection>
</SfRangeNavigator>Run the application
Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor Range Selector component will render in your default web browser.
Open the terminal and run the following command.
dotnet runOpen the command prompt and run the following command.
dotnet run
