Major version chapter Latest generation

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 150 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 150

  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.
