LeptonX Blazor UI

LeptonX theme is implemented and ready to use with ABP. No custom implementation is needed for Blazor Server & WebAssembly.

Installation

• Add Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXTheme package to your Blazor WASM application.

  dotnet add package Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXTheme
  

• Remove old theme from DependsOn attribute in your module class and add AbpAspNetCoreComponentsWebAssemblyLeptonXThemeModule type to DependsOn attribute.

[DependsOn(
-    typeof(LeptonThemeManagementBlazorModule),
-    typeof(AbpAspNetCoreComponentsWebAssemblyLeptonThemeModule),
+    typeof(AbpAspNetCoreComponentsWebAssemblyLeptonXThemeModule)
)]

• Change startup App component with the LeptonX one.

  • Add following using declaration and remove your old theme using declaration.

    using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components;
    

  • Make sure App component in following block is Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.App

        // Make sure the 'App' comes from 'Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components' namespace.
        builder.RootComponents.Add<App>("#ApplicationContainer");
    

    • If you can't remove or not sure which one is the old theme's using statements, you can use full name of that class:

      builder.RootComponents.Add<Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.App>("#ApplicationContainer");
      

Source-Code

You can download the source-code of the LeptonX Theme according to you your ABP License.

Visit the LeptonX Source Code section to download the source-code.

Customization

Before starting to customize the theme, you can consider downloading the source code of the theme. You can find the original codes of related components below in the source code.

Themes

You can set default theme or add or remove themes via using LeptonXThemeOptions.

• DefaultStyle: Defines deffault fallback theme. Default value is Dim

  Configure<LeptonXThemeOptions>(options =>
  {
      options.DefaultStyle = LeptonXStyleNames.Dark;
  });
  

• Styles: Defines selectable themes from UI.

  

  Configure<LeptonXThemeOptions>(options =>
  {
      // Removing existing themes
      options.Styles.Remove(LeptonXStyleNames.Light);
  
      // Adding a new theme
      options.Styles.Add("red", 
          new LeptonXThemeStyle(
          LocalizableString.Create<YourResource>("Theme:Red"),
          "bi bi-circle-fill"));
  });
  
  

  red.css and bootstrap-red.css have to be added under the wwwroot/_content/Volo.Abp.AspNetCore.Components.Web.LeptonXTheme/side-menu/css/ folder to switch to your custom theme properly when selected.

  If your layout is TopMenu, then you have to add them under the wwwroot/_content/Volo.Abp.AspNetCore.Components.Web.LeptonXTheme/top-menu/css/ folder.

  

LeptonXThemeBlazorOptions

Layout options of Blazor UI can be manageable via using LeptonXThemeMvcOptions.

• Layout: Layout of main application. Default value is LeptonXMvcLayouts.SideMenu

  Configure<LeptonXThemeBlazorOptions>(options =>
  {
      options.Layout = LeptonXBlazorLayouts.SideMenu;
      // Or your custom implemented layout:
      options.Layout = typeof(MyCustomLayoutComponent);
  });
  

• MobileMenuSelector: Defines items to be displayed at mobile menu. Default value is first 2 items from main menu items.

  

  Configure<LeptonXThemeBlazorOptions>(options =>
  {
      options.MobileMenuSelector = items => items.Where(x => x.MenuItem.Name == "MyProjectName.Home" || x.MenuItem.Name == "MyProjectName.Dashboard");
  });
  

Updating Bundles on Layout Changes

Layout changes requires bundling and restarting the application. Before bundling, you have to add your layout to appsettings.json. Make sure AbpCli:Bundle:Paramters has LeptonXTheme.Layout key with your layout name. Available values are side-menu & top-menu.

You can add the following section to root level of your appsettings.json file if not added.

  "AbpCli": {
    "Bundle": {
      "Mode": "BundleAndMinify", /* Options: None, Bundle, BundleAndMinify */
      "Name": "global",
      "Parameters": {
        "LeptonXTheme.Layout": "top-menu" /* Options: side-menu, top-menu */
      }
    }
  }

Then you can run bundling command with ABP Cli

abp bundle

Layouts

LeptonX offers two ready-made layouts for your web application. One of them is placed with the menu items on the top and the other with the menu items on the sides.

Top Menu Layout

Side Menu Layout

You can override layouts by following the steps below:

• Create a razor page, like MySideMenuLayout.razor, in your blazor application as shown below:

@using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout;
@using Volo.Abp.DependencyInjection

@inherits SideMenuLayout
@attribute [ExposeServices(typeof(SideMenuLayout))]
@attribute [Dependency(ReplaceServices = true)]

@Name

• If you prefer to use a code-behind file for the C# code of your component, create a razor component, like MySideMenuLayout.razor.cs, in your blazor application as shown below:

using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout;
using Volo.Abp.DependencyInjection;

namespace LeptonXLite.DemoApp.Blazor.MyComponents
{
    [ExposeServices(typeof(SideMenuLayout))]
    [Dependency(ReplaceServices = true)]
    public partial class MySideMenuLayout
    {
        public string Name = "My Top Layout";
    }
}

Don't forget to remove repeated attributes from the razor page!
