Cleaning Word Formatting with the StripFormattingOptions

  • NoneSupressCleanMessage: Doesn't strip anything on paste and does not prompt user whether MS formatting should be cleaned.
  • None: If no MS Word formatting is detected, content is pasted as is. If MS Word formatting exists, user is prompted to clean it.
  • MSWord: strips Word-specific tags, preserving fonts and text sizes.
  • MSWordNoMargins: strips Word-specific tags and margins, preserving fonts and text sizes.
  • MSWordNoFonts: strips Word-specific tags, preserving text sizes.
  • MSWordRemoveAll: strips Word-specific tags, fonts and text sizes.
  • Css: strips CSS styles.
  • Font: strips Font tags.
  • Span: strips Span tags.
  • ConvertWordLists: converts Word ordered/unordered lists to HTML tags.
  • AllExceptNewLines: Clears all tags except "<br />" and new lines (\n).
  • All: strips all HTML formatting and pastes plain text.

Cleaning Word Formatting via Tools in the RadEditor Toolbar

  • Strip Word-formatting on paste - The "Paste from Word" button Paste From Word button allows you to strip the Word-specific tags from the text copied in the clipboard and will paste it in RadEditor with a single click.
  • Strip Word-formatting on paste (cleaning fonts and sizes) - The "Paste from Word cleaning fonts and sizes" button Paste From Word No Fonts No Sizes button will clean all Word-specific tags plus and will remove font names and text sizes, as they are rarely used in the web environment.
  • Forced format stripping on Paste - Developers can now enforce content formatting using the new StripFormattingOptions property. As a result, format stripping will be applied to all pasted content, with the following options: None, MSWord (retains fonts and sizes), MSWordNoFonts, MSWordRemoveAll, Css, Font, Span, All.
  • Word Content in Clipboard Interception - In case the user is trying to paste Word content with the regular Paste button or Ctrl+V, a dialog will prompt whether the Word markup should be cleaned. If the Clipboard content does not come from Word, the dialog will not be shown.
  • Strip Word-formatting after paste - As an alternative to the "Paste from Word" tool (item 1) you may paste the formatted content first and then strip it using the "Format Stripper" tool.
  • Paste plain text - The "Paste Plain Text" button Paste Plain Text button works similarly to "Paste from Word" Paste From Word button , but it removes all HTML formatting and pastes plain text, preserving the line breaks.
  • Paste as HTML - This new tool Paste As Html button allows you to paste the HTML content of the Clipboard as code, which may be quite convenient for developer-oriented applications (e.g. support systems, forums, etc.)
  • Strip formatting on submit - Formatting can also be stripped automatically on page submit for browsers that do not provide onpaste event using the OnClientSubmit event and FormatStripper command of RadEditor, e.g.

    <script type="text/javascript">
    function OnClientSubmit(editor)
         editor.fire("FormatStripper", {value : "WORD"});
    <telerik:RadEditor runat="server" OnClientSubmit="OnClientSubmit"/>
    The avalable options for the FormatStripper command are ALL, ALL_NO_BRAKES, CSS, SPAN, FONT, WORD, WORD_ALL and WORD_NO_FONTS.
