File-Level Changes

Change	Details	Files
Enhance PdfReader sample documentation to describe new features and dependencies.	Add localized description paragraph for using FontAwesome icons with PdfReader. Show the required link tag for including the BootstrapBlazor FontAwesome CSS asset in the sample. List and explain setting a PDF stream and the new DownloadFileName parameter in the demo introduction section.	src/BootstrapBlazor.Server/Components/Samples/PdfReaders.razor
Wire up localization resources for the new PdfReader descriptions.	Add English resource strings for FontAwesome usage, PDF stream configuration, and DownloadFileName parameter documentation. Add Chinese resource strings mirroring the new English entries for the PdfReader demo.	src/BootstrapBlazor.Server/Locales/en-US.json src/BootstrapBlazor.Server/Locales/zh-CN.json
Adjust server project configuration if needed for new assets or sample changes.	Update project references or static asset configuration related to BootstrapBlazor.FontAwesome or PdfReader samples, if applicable.	src/BootstrapBlazor.Server/BootstrapBlazor.Server.csproj

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#7355	Ensure PdfReader reliably renders and displays page content after its content is set, including in scenarios involving StateHasChanged, overlays (z-index), and modals, potentially by adding a refresh mechanism or similar fix.	❌	The PR only updates the PdfReaders sample component and localization text (e.g., adding description items and FontAwesome CSS usage). There are no changes to PdfReader logic, rendering behavior, or any new refresh mechanism that would affect how or when pages render after content is set.
#7355	Modify the PdfReader print behavior so that the print button prints only the PDF content displayed in the reader rather than the entire web page.	❌	The PR does not touch any print-related code, buttons, or PdfReader internals. It only updates demo markup and localized descriptions, so it cannot change what the print button prints.

Hey there - I've reviewed your changes - here's some feedback:

• The added Localizer[...] keys like PdfReaderFAIconDesc, PdfReaderSetPdfStreamDesc, and PdfReaderDownloadFileNameDesc rely on new locale entries—double-check that they are defined consistently across all supported locale JSON files and that there are no missing or mismatched keys.
• The hard-coded FontAwesome stylesheet link in the demo could be factored into a shared partial/component or configuration-driven helper to avoid duplication and make future asset path changes easier to manage.
• The PR title and new text refer to DownloadFileNanme; if any parameter or API surface uses this misspelling, consider correcting it now to avoid a persistent typo in the public API.
