This section briefly explains about how to include Color Picker Component in your Blazor server-side application. You can refer Getting Started with Syncfusion Blazor for Server-side in Visual Studio 2019 page page for the introduction and configuring the common specifications.

Importing Syncfusion Blazor component in the application

  1. Install the Syncfusion.Blazor NuGet package to the application by using the NuGet Package Manager.

  2. You can add the client-side style resources through CDN or from NuGet package in the <head> element of the ~/Pages/_Host.chtml page.

Please ensure to check the Include prerelease option.

<head>
        <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
        @*<link href="https://cdn.syncfusion.com/blazor/18.1.54/styles/bootstrap4.css" rel="stylesheet" />*@
</head>

        <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
</head>

Adding component package to the application

Open /_Imports.razor file and import the Syncfusion.Blazor.Inputs package.

@using Syncfusion.Blazor.Inputs

Add SyncfusionBlazor service in Startup.cs

Open the Startup.cs file and add services required by Syncfusion components. Add services.AddSyncfusionBlazor() method in the ConfigureServices function as follows.

namespace BlazorApplication
{
    public class Startup
    {
        ....
        ....
        public void ConfigureServices(IServiceCollection services)
        {
            ....
            ....
            services.AddSyncfusionBlazor();
        }
    }
}

To enable custom client side resource loading from CRG or CDN. You need to disable resource loading by AddSyncfusionBlazor(true) and load the scripts in the HEAD element of the ~/Pages/_Host.cshtml page.

    <environment include="Development">
        <script src="https://cdn.syncfusion.com/blazor/18.1.54/syncfusion-blazor.min.js">
        </script>
    </environment>
</head>
