1 Feb 20244 minutes to read

This section briefly explains about how to include Blazor DatePicker component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

To get start quickly with Blazor DatePicker component, you can check on this video or GitHub sample.

Prerequisites

System requirements for Blazor components

Create a new Blazor App in Visual Studio

You can create a Blazor Server App or Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion Blazor Extension.

Install Syncfusion Blazor Calendars and Themes NuGet in the App

To add Blazor DatePicker component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Calendars and Syncfusion.Blazor.Themes. Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.Calendars -Version 25.1.35
Install-Package Syncfusion.Blazor.Themes -Version 25.1.35

NOTE

Syncfusion Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Calendars namespace.

~/_Imports.razor

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Calendars

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Server App or Blazor WebAssembly App.

Blazor Server App
Blazor WebAssembly App
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Reference the stylesheet and script in the <head> of the main page as follows:

For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.
For .NET 7 Blazor Server app, include it in the ~/Pages/_Host.cshtml file.
For Blazor WebAssembly app, include it in the ~/index.html file.

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>

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 Blazor DatePicker component

Add the Syncfusion Blazor DatePicker component in the ~/Pages/Index.razor file.

RAZOR
<SfDatePicker TValue="DateTime?" Placeholder='Choose a Date'></SfDatePicker>

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

Setting the Value and Min and Max dates

The following example demonstrates how to set the Value and Min and Max dates on initializing the DatePicker. Here, you can select a date within the range from 5th to 27th of this month. TValue specifies the type of the DatePicker component.

RAZOR
<SfDatePicker TValue="DateTime?" Value='@DateValue' Min='@MinDate' Max='@MaxDate'></SfDatePicker>

@code {
    public DateTime? DateValue {get;set;} = new DateTime(DateTime.Now.Year,DateTime.Now.Month,10);
    public DateTime MinDate {get;set;} = new DateTime(DateTime.Now.Year,DateTime.Now.Month,05);
    public DateTime MaxDate {get;set;} = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 27);
}
