Workflow

Prerequisites

• MudBlazor Installed and configurated.

Installation

Install Package

dotnet add package MudBlazor.ThemeManager

Add the following to _Imports.razor

@using MudBlazor.ThemeManager

Add the following to your HTML head section, it's either index.html or _Layout.cshtml/_Host.cshtml/App.razor depending on whether you're running WebAssembly or Server.

<link href="https://fonts.googleapis.com/css2?family=Ubuntu:wght@300;400;500;700&display=swap" rel="stylesheet">
<link href="https://fonts.googleapis.com/css2?family=Montserrat:wght@400;500;600;700&display=swap" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap" rel="stylesheet" />
<link href="_content/MudBlazor.ThemeManager/MudBlazorThemeManager.css" rel="stylesheet" />

Add the components in your MainLayout.razor and inside <MudLayout>

<MudThemeManagerButton OnClick="@((e) => OpenThemeManager(true))" />
<MudThemeManager Open="_themeManagerOpen" OpenChanged="OpenThemeManager" Theme="_themeManager" ThemeChanged="UpdateTheme" IsDarkMode="@_isDarkMode" />

Add the following inside your @code for MainLayout.razor

private ThemeManagerTheme _themeManager = new ThemeManagerTheme();
private bool _themeManagerOpen = false;
private bool _isDarkMode;

void OpenThemeManager(bool value)
{
    _themeManagerOpen = value;
}

void UpdateTheme(ThemeManagerTheme value)
{
    _themeManager = value;
    StateHasChanged();
}

protected override void OnInitialized()
{
    StateHasChanged();
}

Dark Mode Support

If you need dark mode support, make sure to bind the IsDarkMode parameter to a variable that controls whether your application is in dark mode. This allows the Theme Manager to adjust and display the appropriate palette (light or dark) when you're customizing themes.

The _isDarkMode variable should be synchronized with your MudThemeProvider's IsDarkMode to ensure consistent dark mode behavior across your application:

<MudThemeProvider Theme="_themeManager.Theme" @bind-IsDarkMode="@_isDarkMode" />

Connect the ThemeManagerTheme with MudThemeProvider to control all the theme colors. You can also connect MudAppBar and MudDrawer directly.

<MudThemeProvider Theme="_themeManager.Theme" />
<MudAppBar Elevation="_themeManager.AppBarElevation">
<MudDrawer @bind-Open="_drawerOpen" ClipMode="_themeManager.DrawerClipMode" Elevation="_themeManager.DrawerElevation">
