From b16ae70762e031140f0129cbc701ea0e8a202023 Mon Sep 17 00:00:00 2001 From: TekH Date: Thu, 11 Jun 2026 13:02:53 +0200 Subject: [PATCH] Remove signature-related functionality This commit removes all features and UI elements related to signature handling in the `EnvelopeReceiverPage_DxReportViewer.razor` file. Key changes include: - Removed signature creation (drawing, typing, uploading) and associated UI components like the signature popup and action bar. - Removed annotation handling logic, including toggling checkboxes and applying signatures to annotations. - Removed PDF export functionality for signed documents. - Deleted methods and properties related to signature handling, such as `AddSignature`, `OnInitializedAsync`, and `SignaturePopupVisible`. - Removed `@inject` services and JavaScript interop calls related to signature handling. - Simplified the `DxReportViewer` usage to only display the report without overlays or interactions. - Removed envelope metadata display and logout functionality. The page now focuses solely on displaying reports without any signature-related features. --- .../EnvelopeReceiverPage_DxReportViewer.razor | 684 +----------------- 1 file changed, 7 insertions(+), 677 deletions(-) diff --git a/EnvelopeGenerator.ReceiverUI/Pages/EnvelopeReceiverPage_DxReportViewer.razor b/EnvelopeGenerator.ReceiverUI/Pages/EnvelopeReceiverPage_DxReportViewer.razor index 3bee7f8d..6f12b843 100644 --- a/EnvelopeGenerator.ReceiverUI/Pages/EnvelopeReceiverPage_DxReportViewer.razor +++ b/EnvelopeGenerator.ReceiverUI/Pages/EnvelopeReceiverPage_DxReportViewer.razor @@ -1,522 +1,35 @@ @page "/envelope/{EnvelopeKey}/DxReportViewer" -@using System.Drawing -@using DevExpress.Blazor -@using DevExpress.Drawing -@using DevExpress.Utils -@using DevExpress.XtraPrinting -@using DevExpress.XtraPrinting.Drawing -@using Microsoft.JSInterop @using XtraReport = DevExpress.XtraReports.UI.XtraReport -@using BottomMarginBand = DevExpress.XtraReports.UI.BottomMarginBand -@using XRLabel = DevExpress.XtraReports.UI.XRLabel -@using XRPictureBox = DevExpress.XtraReports.UI.XRPictureBox -@using XRControl = DevExpress.XtraReports.UI.XRControl -@using ImageSizeMode = DevExpress.XtraPrinting.ImageSizeMode -@using EnvelopeGenerator.ReceiverUI.Services @using DevExpress.Blazor.Reporting @using Microsoft.Extensions.Options @using EnvelopeGenerator.ReceiverUI.Options -@using EnvelopeGenerator.ReceiverUI.Models -@implements IDisposable -@inject IJSRuntime JSRuntime -@inject AnnotationService AnnotationService -@inject IOptions AppOptions -@inject NavigationManager Navigation +@using EnvelopeGenerator.ReceiverUI.Services @inject InMemoryReportStorageWebExtension ReportStorage -@inject EnvelopeGenerator.ReceiverUI.Services.DocumentService DocumentService -@inject EnvelopeGenerator.ReceiverUI.Services.AuthService AuthService -@inject EnvelopeGenerator.ReceiverUI.Services.EnvelopeReceiverService EnvelopeReceiverService +@inject DocumentService DocumentService +@inject IOptions AppOptions -
