BlazorColorPicker 4.0.0

Blazor-Color-Picker

Sometimes HTML5 colorpicker doesn't suit me for an application. I prefer to offer the user a predefined color palette

DEMO : https://tossnet.github.io/Blazor-Color-Picker/

Opens a palette with the Material colors

Installation

Latest version in here:

To Install

Install-Package BlazorColorPicker

or

dotnet add package BlazorColorPicker

For client-side and server-side Blazor - add script section to index.html or _Host.cshtml (head section)

<link href="_content/BlazorColorPicker/colorpicker.css" rel="stylesheet" />

In program.cs, declare

builder.Services.AddScoped<IColorPickerService, ColorPickerService>();

ColorPicker are rendered by the <BlazorColorPicker.ColorPicker />. This component needs to be added to the main layout of your application/site. You typically do this in the MainLayout.razor file at the end of the <main> section.

Usage

@page "/"
@using BlazorColorPicker

@inject IColorPickerService ColorPickerService

<h1>Hello, world!</h1>

<button class="btn btn-primary" @onclick="OpenModal">
    <div style="background-color:@color" class="buttonColor"></div> Select a Color
</button>

@code {
    private string color = "#F1F7E9";

    private async Task OpenModal()
    {
        var parameters = new ColorPickerParameters
        {
        	ColorSelected = color,
        };
        color = await ColorPickerService.ShowColorPicker(parameters);
    }
}
