From 3b367eff7face4874cb95f7b8804f26da38f2c29 Mon Sep 17 00:00:00 2001 From: TekH Date: Fri, 2 Oct 2026 13:39:00 +0200 Subject: [PATCH] Remove `EnvelopeSenderEditorPage.razor` entirely The `EnvelopeSenderEditorPage.razor` file was completely removed, including all Razor markup, Blazor components, JavaScript references, CSS styles, and C# code-behind logic. Key changes: - Removed the `/sender/editor_legacy` route and all associated imports (`@using`) and dependency injections (`@inject`). - Deleted the entire HTML structure, including UI elements for PDF editing, signature placement, and receiver management. - Removed all references to external CSS and JavaScript files. - Deleted Blazor components like `DxPdfViewer`, `DxPopup`, and `DxTextBox`. - Removed C# code for state management, lifecycle methods, event handlers, and helper methods. - Eliminated localization, validation logic, session persistence, and cache management. - Removed PDF manipulation logic (e.g., placeholder rendering with `PdfSharp`). - Deleted receiver management logic, including email suggestions and validation. This change removes the entire functionality of the `EnvelopeSenderEditorPage`, including its UI, backend logic, and external integrations. --- .../Pages/EnvelopeSenderEditorPage.razor | 1292 ----------------- 1 file changed, 1292 deletions(-) delete mode 100644 EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeSenderEditorPage.razor diff --git a/EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeSenderEditorPage.razor b/EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeSenderEditorPage.razor deleted file mode 100644 index e2d0199c..00000000 --- a/EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeSenderEditorPage.razor +++ /dev/null @@ -1,1292 +0,0 @@ -@page "/sender/editor_legacy" -@rendermode InteractiveServer -@using DevExpress.Blazor.PdfViewer -@using DevExpress.Blazor.Reporting.Models -@using DevExpress.Blazor -@using EnvelopeGenerator.Application.Common.Dto -@using EnvelopeGenerator.Application.Envelopes.Commands -@using EnvelopeGenerator.Application.Resources -@using EnvelopeGenerator.Server.Client.Services -@using EnvelopeGenerator.Server.Services -@using Microsoft.AspNetCore.WebUtilities -@using Microsoft.AspNetCore.Components.Forms -@using Microsoft.Extensions.Caching.Memory -@using Microsoft.Extensions.Localization -@inject IJSRuntime JSRuntime -@inject NavigationManager NavigationManager -@inject AppVersionService AppVersion -@inject ILogger Logger -@inject EnvelopeReceiverPageDataService ReceiverPageDataService -@inject EnvelopeService EnvelopeService -@inject IEnvelopeAuthService EnvelopeAuthService -@inject IMemoryCache MemoryCache -@inject IStringLocalizer UiLocalizer - - - - - - -
