Introduced a new Blazor component `EnvelopeViewer.razor` to display PDF documents with a user-friendly interface. The component supports dynamic routing via `/envelope/{EnvelopeKey}` and integrates the `pdf.js` library for efficient PDF rendering in the browser.
Key features include:
- Zoom and navigation controls (Next/Previous page, Zoom In/Out).
- Loading spinner, error handling, and fallback UI for robustness.
- Responsive design with modern styling using CSS.
- JavaScript interop via `pdf-viewer.js` for managing PDF rendering, scaling, and navigation.
Added lifecycle methods (`OnInitializedAsync`, `OnAfterRenderAsync`) for dynamic loading and rendering. Ensured asynchronous operations for smooth user interactions. Included a `DisposeAsync` method for cleanup.
The `ForceToUseFakeDocument` property in the `Api` section of
`appsettings.json` was changed from `true` to `false`. This
modification alters the application's behavior to no longer
force the use of fake documents, potentially enabling the use
of real documents or other configurations as defined by the
application logic.
Adjusted the y-coordinate values for annotations with id 1, 2,
and 3 in annotations.json to reposition them on their respective
pages:
- Changed y for id 1 from 980.0 to 380.0.
- Changed y for id 2 from 980.0 to 680.0.

Updated the content in `Index.razor` to describe the digital signature portal's features and removed redundant UI elements, including a document signing button and a feature badge.
Modified `ReportViewer.razor` to remove the `/receiver` route, leaving only `/receiver/{EnvelopeKey}`. Updated the `EnvelopeKey` parameter to be non-nullable with a default value, improving type safety and preventing null reference issues.
Replaced the old card-based layout in `Index.razor` with a modern, visually appealing home page design. Added a hero header, content section, and call-to-action button for signing documents. Introduced new SVG icons and text elements to enhance the UI.
Removed the `OnAfterRenderAsync` method and automatic redirection logic to simplify user navigation. Added a new stylesheet link for the DevExpress Blazor theme.
Updated `app.css` to support the new design:
- Changed `article` overflow to `overflow-y: auto`.
- Added new classes for layout, buttons, and feature badges.
- Styled the home page with a gradient background, rounded corners, and hover effects.
These changes improve usability, responsiveness, and visual consistency.
Introduced a new footer in `MainLayout.razor` with copyright
information, a link to "Digital Data GmbH," and a privacy
policy link. Added two new privacy policy files
(`privacy-policy.en-US.html` and `privacy-policy.fr-FR.html`)
to the project and configured them to always copy to the
output directory.
Updated `app.css` to adjust layout heights to accommodate
the footer. Added new styles for the footer, including a
gradient background, responsive design, and hover effects

Added `AnnotationDto` to represent signature annotation positions,
including properties for ID, page, and coordinates, with detailed
documentation on coordinate systems. Implemented `AnnotationService`
to fetch annotation data from an API endpoint, using `HttpClient`
and supporting cancellation tokens. Registered `AnnotationService`
in the DI container to enable its use across the application.
Provided development setup details for working with fake data
via YARP-proxied routes.
Added three new annotation objects to `annotations.json`.
Each annotation includes an `id`, `page`, `x`, and `y` property.
The annotations are for pages 1, 2, and 3, all with the same
coordinates (390.0, 980.0).
Refactored the `AnnotationCreateDto` class:
- Changed `ElementId` from `int` to `long` and made it mutable.
- Marked `Name`, `Value`, and `Type` as `[Obsolete]` with defaults.
- Added `[Obsolete]` attributes to `Width` and `Height`.
- Introduced a new `Page` property to replace `SignatureDto`.
Updated `appsettings.json`:
- Set `Api.BaseUrl` to an empty string.
Introduced a "Logout" button in `ReportViewer.razor` that is displayed when an `EnvelopeKey` is present. The button includes a spinner to indicate progress during the logout process.
Added the `LogoutAsync` method in `ReportViewer.razor` to handle the logout operation, preventing multiple attempts and navigating the user to the login page upon success.
Implemented `LogoutEnvelopeReceiverAsync` in `AuthService` to send a POST request to remove the per-envelope receiver cookie. This ensures proper backend handling of the logout process.
Improved user experience by providing a responsive and clear logout mechanism for envelope-based sessions.
Added a new `/login/{**catch-all}` route in `yarp.json` for the `receiver-ui` cluster. Updated `Login.razor` with a modernized UI, including a gradient header, improved error handling, and a toggle for password visibility. Integrated `AuthService` for API-based login validation.
Refactored `Login.razor` logic to handle login outcomes (`Success`, `InvalidCode`, `NotFound`, `Error`) using the new `EnvelopeLoginResult` enum. Added `LoginEnvelopeReceiverAsync` method in `AuthService` to handle login requests via `POST /api/Auth/envelope-receiver/{key}`. Improved code maintainability and user experience.
Introduced a new login page (`Login.razor`) to handle user authentication via access codes. Implemented `AuthService` to validate access codes through an API. Updated `ReportViewer.razor` to check user access and redirect unauthorized users to the login page. Modified `Program.cs` to register `AuthService` for dependency injection. Enhanced document fetching in `ReportViewer.razor` to ensure secure access control.
Replaced `DxPdfViewer` with `DxReportViewer` to unify handling of
both PDF and report rendering. Removed conditional logic for
`PdfBytes` and directly initialized `XtraReport` with PDF content
using `XRPdfContent`. Simplified `OnInitializedAsync` to fetch
PDF content, create a report, and store it in `ReportStorage`.
Removed unused fields (`PdfViewerUrl`, `PdfBytes`, and
`SignedPdfBytes`) and redundant code related to PDF handling.
Refactored the signature handling process by introducing a new
`Report` instance creation step in the `SignatureApplied` block
to streamline signed report generation. Added a validation check
in `ExportSignedPdfAsync` to ensure the `Report` object is not
null before proceeding with export. Removed redundant code for
manual signed report creation and simplified the export logic
by directly invoking `reportViewer!.ExportToAsync`. Incremented
`ViewerKey` to refresh the report viewer after signing.
Updated the `OnInitializedAsync` method in `ReportViewer.razor`
to include a check for `AppOptions.Value.ForceToUseFakeDocument`.
This ensures that the application can bypass fetching the
actual document when the configuration option is enabled.
Introduced a new `ForceToUseFakeDocument` property in `ApiOptions` to control whether the application uses a fake document for testing or bypasses certain conditions for document loading. Updated `ReportViewer.razor` to respect this configuration, including changes to conditional rendering logic and dependency injection for `IOptions<ApiOptions>`.
Removed test code that forced `EnvelopeKey` to `null` during initialization. Updated `appsettings.json` to include the new `ForceToUseFakeDocument` property with a default value of `true`. Added necessary `using` directives and dependencies for the updated functionality.
Introduced a new `DocumentService` class to handle fetching
PDF document bytes from an API endpoint. The service uses
`HttpClient` for HTTP communication and `IOptions<ApiOptions>`
for accessing API configuration. Added the `GetDocumentAsync`
method to perform the HTTP GET request, handle responses, and
return the document bytes along with the HTTP status code.
Included necessary `using` directives and encapsulated the
service in the `EnvelopeGenerator.ReceiverUI.Services` namespace.
Added a new `ApiOptions` class to encapsulate API configuration,
including the `BaseUrl` property and `SectionName` constant.
Registered `ApiOptions` in the dependency injection container
in `Program.cs` and bound it to the "Api" section in the
configuration file. Updated `appsettings.json` to include the
"Api" section with a `BaseUrl` value of "https://localhost:8088".
Integrated DevExpress WebAssembly Blazor Report Viewer and PDF Viewer to enable report and PDF rendering in the application.
Registered `EnvelopeGenerator.ReceiverUI.Services.DocumentService` for document handling. Configured `DevExpress Blazor Reporting WebAssembly` in development mode.
Added a custom implementation of `IDataSourceWizardJsonConnectionStorage` to manage JSON data connections in the data source wizard.
Upgraded DevExpress package references in `EnvelopeGenerator.ReceiverUI.csproj` from version 25.2.3 to 25.2.7, including:
- `DevExpress.Drawing.Skia`
- `DevExpress.Blazor.Reporting.JSBasedControls`
- `DevExpress.Blazor.Reporting.Viewer`
Added a new package reference for `DevExpress.Blazor.PdfViewer` (version 25.2.7) to enable PDF viewing functionality.
Updated `_Imports.razor` to include `@using DevExpress.Blazor.PdfViewer` for PdfViewer component support.
Enhanced `ReportViewer.razor` with a new layout structure:
- Added `receiver-page-layout` with `receiver-signature-panel` and `receiver-viewer-wrapper` for better organization.
- Introduced a button to export signed PDFs, conditionally enabled based on `SignatureApplied`.
- Added a `DxPopup` for capturing signatures with a "Close" button.
Updated `MainLayout.razor` to remove unnecessary padding from `<article>`.
Refined `app.css`:
- Defined styles for `receiver-page-layout`, `receiver-signature-panel`, and `receiver-viewer-wrapper` to improve layout flexibility.
- Adjusted `article` to use flexbox and ensure hidden overflow.
Updated the `OnAfterRenderAsync` method in `Index.razor` to navigate to `/receiver` instead of `/reportviewer`. Removed the sidebar containing the `<NavMenu />` component in `MainLayout.razor` and adjusted the `<main>` tag to directly contain the content.
Updated the `@page` directives in `ReportDesigner.razor` and
`ReportViewer.razor` to change routes from `/reportdesigner`
to `/sender` and `/reportviewer` to `/receiver`, respectively.
Modified `NavMenu.razor` to update navigation links to reflect
the new routes. Updated the displayed text for the links to
"Empfänger-UI" (Receiver UI) and "Umschlag-UI" (Envelope UI).
Updated EnvelopeGenerator.ReceiverUI.csproj to enable native WebAssembly builds and load all globalization data for improved localization support.
Refactored ReportViewer.razor to enhance layout calculations for the signature section:
- Introduced constants for better readability and maintainability.
- Dynamically adjusted band height and padding to fit content without overlap.
- Updated control positioning and sizing using calculated values.
- Changed font style of the signature label to regular and reordered control additions for clarity.
The `<WasmBuildNative>` property in the `EnvelopeGenerator.ReceiverUI.csproj` file was changed from `true` to `false`. This disables the native WebAssembly (Wasm) build, potentially simplifying the build process, reducing build time, or addressing compatibility issues.
Increased the `bottomMargin` height from 140F to 175F to provide additional space. Updated the `signatureInformation` format to simplify text structure, remove redundant labels, and use a short date format.
Modified the `XRLabel` to enable multiline text, adjusted its height to 70F, and changed text alignment to `TopLeft`. Updated the `XRPictureBox` position by shifting its Y-coordinate to 80F for better alignment with the new layout.
