This document describes assemblies required by web projects that use the functionality of the ASPxHtmlEditor control. Some of the assemblies are essential, while others that provide additional functionality can be optionally deployed, depending on your requirements.

We recommend you use our Assembly Deployment Tool, which allows you to automatically collect the required redistributable DevExpress (and custom) assemblies to deploy your application. Otherwise, you can deploy the required assemblies manually.


If you use other DevExpress components in your project, using and deploying them should comply with corresponding EULA documents. For more details on licensing information and the redistribution policy of DevExpress, refer to Redistribution and Deployment.

Depending upon the permissions you have on a production server and the amount of web applications that use the same assemblies provided by DevExpress, you can either register the assemblies in the global system assembly cache (GAC) or place them into the Bin folder of your application on the target computer. To learn more about web project deployment techniques, see ASP.NET Deployment Content Map.

Required Libraries

Below are the essential libraries required by applications that use the ASPxHtmlEditor control. These libraries are considered to be redistributable under the .NET Controls & Frameworks EULA, and thus can be redistributed legally.




Implements the most basic functionality common to all DevExpress controls. This includes classes for data binding, skinning, printing, exporting, as well as many other auxiliary types and resources.


Contains classes that implement the core functionality of all DevExpress web controls and the functionality of controls from the following components: Data Editors, GridView, Card View, Vertical Grid, Data and Image Navigation, Docking and Popups, Site Navigation and Layout, File Management and Multi-Use Site Controls.


Contains an assortment of internal classes that implement the basic spell-checker functionality of WinForms SpellChecker, ASP.NET SpellChecker, and WPF SpellChecker controls.


Contains classes that implement the ASPxSpellChecker component’s functionality. See Spell Checker and DevExpress.Web.ASPxSpellChecker to learn more.


Contains classes that implement the basic functionality for DevExpress printing libraries.


Contains classes that implement the logic for formatting rich text, as well as basic types that provide a public API common to such DevExpress RTF controls as ASP.NET RichEdit, WinForms RichEdit, and WPF RichEdit.

This assembly is also required when using a Rich Edit in-place editor (RepositoryItemRichTextEdit) and/or exporting to DOCX.


Contains base classes common for Office File API and Office controls.


Contains classes that implement a functionality of the ASPxHtmlEditor control. See HTML Editor and DevExpress.Web.ASPxHtmlEditor to learn more.

Optional Libraries

The following libraries provide additional functionality for web projects that use the functionality of the ASPxHtmlEditor control.


  • DevExpress Themes

    If any provided DevExpress Theme is used, the following assembly should also be deployed. This library is considered to be redistributable under the .NET Controls & Frameworks EULA.




    Contains classes that implement a set of predefined DevExpress themes for DevExpress web controls. See ASPxThemes Assembly to learn more.


  • Export to DOCX or RTF format

    If you export the ASPxTreeList content to DOCX or RTF format, deploy the following assembly:

    Assembly Description
    DevExpress.RichEdit.v20.2.Export.dll Contains classes required for export to DOCX and RTF format.
  • Using in SharePoint

    If ASPxHtmlEditor is integrated into the SharePoint environment, the following assemblies should be registered within the SharePoint server’s GAC. These libraries are considered to be redistributable under the .NET Controls & Frameworks EULA. See Installation to learn more about DevExpress SharePoint solutions that automatically register required assemblies.




    Contains classes that implement integration of ASPxGridView and ASPxHtmlEditor into the SharePoint 2013 environment. See ASPxGridView - Support for SharePoint and ASPxHtmlEditor - Support for SharePoint to learn more.

  • Localization

    If you localize ASPxHtmlEditor using the satellite resource assemblies, you need to deploy the corresponding assemblies. To learn more, see the Localizing ASP.NET Controls via Satellite Resource Assemblies topic.
