Hi ABP Team,
I’m currently working on a branch where we are integrating DevExpress components into our ABP-based Blazor application.
We’ve encountered an issue related to the admin/user menu in the top bar. After logging in successfully, the admin/user icon (which normally appears in the header and allows actions like Logout) is not being displayed.
In other branches (without the DevExpress integration), the user menu appears correctly after authentication.
So I’d like to understand:
- How is the admin/user icon (login/profile/logout dropdown) rendered internally in ABP Blazor?
- Is it tied specifically to a layout component (e.g., MainLayout, TopBar, AccountLayout, etc.)?
- Are there specific services, components, or required layout sections that must be preserved for the user menu to render?
- Could replacing or customizing the layout (for example, when integrating DevExpress templates) prevent the user menu from appearing?
- Is the visibility of this component dependent on a specific permission, theme (LeptonX), or injected service?
We suspect that something in the layout structure may have been overridden or removed when integrating DevExpress UI components.
Any guidance on how the login/profile/logout UI is internally wired in ABP would be very helpful.
Thank you in advance.

In ABP Blazor, the login/profile/logout dropdown is not “automatic”; it is rendered by the active UI theme’s layout components (e.g., LeptonX/Basic theme). Concretely, the theme’s
MainLayout(or header/topbar component used by that layout) includes a user menu/login display component in the header toolbar. If you replace the layout/topbar and don’t include that component (or an equivalent), the icon/menu will not show.So yes: it is tied to the layout structure (MainLayout/TopBar/toolbar region). When integrating DevExpress templates, it’s very common to accidentally remove the theme’s header toolbar (or replace it with a new one) and therefore lose the user menu.
It is not primarily permission-based. The usual visibility logic is based on authentication state (e.g., rendered inside
<AuthorizeView>: show user dropdown when authenticated, otherwise show Login link/button). Theme (LeptonX vs Basic) changes which component renders it, but the concept is the same.What you must preserve (or re-add in your custom DevExpress layout):
- A header/topbar area that renders the theme’s “toolbar” content (where the user menu component lives).
- The ABP/theming infrastructure used by that theme (i.e., don’t remove the theme’s layout composition points).
- If you fully replace the header, explicitly render your own user menu using Blazor auth primitives (e.g.,
<AuthorizeView>) and ABP services for user/tenant/menu if needed.
If you are using LeptonX (Blazor), the official LeptonX Blazor UI docs list the layout and “Top Menu Components” involved. When you replace a LeptonX layout with a DevExpress layout, you typically need to carry over the topbar components (including the user menu component) into your new layout.
