Modern Source Editing and More Reliable WinForms HTML Authoring

Versions 10.0.0 through 10.0.2 expanded HTML authoring with a modern syntax-highlighted source experience, practical content and print configuration, and richer paste options.

  2. Added page properties and printer-settings customization for document and printing workflows.
  3. Added an emoji picker and support for pasting content from Microsoft Outlook.

Bugs and reliability 13

Major version chapter

v9.0.36 - v9.7.7

WinForms HTML Editor 9.0.36-9.7.7: modern authoring, reliability and integration

This chapter modernized the WinForms editor’s delivery, platform reach and authoring experience while concentrating heavily on content safety. Releases improved Word and Outlook paste fidelity, spell checking, rendering and color selection, then addressed document-loss, HTML round-trip, DPI, designer and localization problems. Migration updates also introduced NuGet delivery, broader framework support and a license-key activation model.

36 features 151 bug fixes 21 interface changes

Major features 36

  1. Improved Word and Outlook authoring: paste auto-detection and enhanced Word paste preserve images, styles, fonts, highlighting, table shading and nested lists.
  2. Added built-in wavy inline spell-check underlines, without separate deployment requirements.
  3. Added BrowserEmulation opt-in for Internet Explorer 11 document mode so modern CSS can render.
  4. Replaced the native color dialog with a customizable built-in picker offering quick-palette and advanced-spectrum views, which reopen in the last-used view.

Bugs and reliability 151

  1. Strengthened document safety by fixing failures that could replace a document body, delete adjacent unselected content, lose saved files, wipe content on mode-switch failure, or drop pre-ready HEAD/body writes.
  2. Corrected HTML editing and source-view fidelity, including malformed round trips, duplicated commented DOCTYPEs, lost attribute quotes, invalid charset output and nested comments.
  3. Resolved display-scale and DPI issues affecting document zoom, CSS pixel sizing and Visual Studio designer control retention on scaled displays.
  4. Closed localization gaps so editor chrome, dialogs, trial and licensing screens use translated text and shipped language files stay consistent.

Interface evolution 21

  1. Moved delivery to the SpiceLogic.HtmlEditor.WinForms NuGet package, with multi-targeting from net45 through net10.0-windows; legacy .NET 2.0 projects must upgrade.
  2. Modernized WinForms assembly and namespace references: use SpiceLogic.HtmlEditor.WinForms instead of SpiceLogic.WinHTMLEditor.WinForm; the WinFormHtmlEditor class name remains.
  3. Replaced legacy activation with the static WinFormHtmlEditor.LicenseKey property, set once at application startup before creating an editor instance.
  4. Added runtime Language localization and an opt-in ShowPlaceholderToolbar API for mail-merge field insertion.

  4. Corrected content-reading issues where GetBodyText returned incorrect text in HTML Edit mode or invalid document encoding could produce an empty document.

Interface evolution 1

  1. Replaced Options.DonotShowWarningDialogAboutImagePasting with Options.PasteImageFromClipboardBehavior, offering Base64, BaseUrl-folder, or None options.
Major version chapter

Bugs and reliability 141

  1. Made content entry and formatting more dependable by addressing list behavior, heading changes, font styling, alignment, and preservation of editable elements.

Interface evolution 3

  1. Removed the RightToLeft property and moved RightToLeft access to Content getter and setter methods to address an IDE form-load bottleneck.
