Main Features

Merge/Unmerge Cells for Inserting Tables, Resize Column Width or Row Height with the Mouse

You have the ability to merge and unmerge cells for inserting tables. You can also manually adjust the column width or row height by dragging the cell boundaries to the desired size.

Design, Source, and Preview Modes

Allow your end users to create and format content in design view with the help of HTML Editor's built-in tools, while your advanced users can work directly in the Source mode. By using the Preview mode users can check how the content will be displayed when added to a real web page.

Customizing the HTML Editor Toolbar

You can customize exactly which buttons appear in the editor. For example, you might want to remove the HTML tab to prevent users from switching the HTML Editor into HTML mode. Or, you might want to remove the New, Open and Save buttons to prevent users from operating files directly.

Native Language Support

By default, all buttons and dialogs are provided in English. Support for other languages is available through the use of the Language.INI file. If you chose to configure it, all string resources used in our control will be obtained primarily from this file. Therefore, you can achieve multilanguage support by customizing the string resources.

Insert and Manipulate Pictures, Tables, Objects

Insert and manipulate various types of objects in the document including tables, images, hyperlinks and symbols etc. The dialog boxes allow you to modify all properties of the inserted or edited objects. With mouse actions, move and resize objects directly on the document in Design mode.

Context Menu for Specific Object

Allow quick modifications of images, tables, paragraphs, and other elements with the help of HTML Editor's contextual menus displayed upon a right click of the item while in design mode.

Printing Support

Calling the ShowPrintDialog method has the same effect as choosing Print from the Windows Internet Explorer File menu. The ShowPrintDialog method can activate the Print dialog box, prompting the user to change print settings. The ShowPrintPreviewDialog method lets you see the web page before you print so you can avoid printing mistakes.

Multi-level Undo/Redo with Action Trails

Leverage the out-of-the-box undo-redo mechanism of HTML Editor control, end-users can gradually work back to fix a mistake by undoing repeatedly.

Send HTML Email with Embedded Images
