Complete Feature List for Karamasoft UltimateSpell

Word®-like Spell Checker — Spell check as you type in any editable area by underlining misspelled words with a red squiggly line. You can right-click on a misspelled word and select a suggestion from a context menu.

Spell Check Dialog Box — Word®-like spell check dialog box to display one spelling mistake at a time, and select one of the suggestions from a listbox. Display text sentence-by-sentence in order to understand the context.

Grammar Check Dialog Box — Grammar check dialog box to display grammar errors one at a time sentence-by-sentence. Requires Microsoft Word 2003 or 2007 installed on the server. Recommended for intranet use only due to the Local System requirements of the IIS application pool. Supports .NET 2.0+.

Show Synonyms — Show the synonyms of a word by right-clicking on it and selecting the Synonyms option in the popup context menu. Supports .NET 2.0+.

High Performance — Spell check very long text areas without compromising any performance hits. Send small portions of the text to the server as needed, while the user spell checks through the text.

Fast Spelling — Spell check 1500 words per second using the provided server-side API. Use the same fast spelling engine for inline spelling, dialog box or API.

Auto Correct — Automatically correct your spelling errors as you type. This feature fixes your spelling mistakes if it finds only one suggestion just like in Microsoft Word®.

Auto Find — Automatically find and spell check all editable controls, or specify a comma separated list of control ids to spell check.

Look Up Meaning — Look up the meaning of a suggested word in an online dictionary that you can configure in the language XML file.

34 Dictionaries — Use any of the 34 dictionaries available on our website, or use your own dictionary text file that contains one word per line.

Custom Dictionaries — Add words to your custom dictionaries, and cache them as regular dictionaries. You can use a server-based custom dictionary and a regular dictionary at the same time.

Medical Dictionary — Use the open-source MeDic dictionary as your regular or custom dictionary, or append the content of the MeDic text file to the end of the English dictionary, and use the combined one.

Multi-Language — Display different wordings in the spell check dialog box based on your language by configuring the language XML file.

Spelling Options — Lots of options to change the behavior of the spell checking engine either on the server-side, or on the client-side.

Cache Dictionary — Automatically caches both regular and custom dictionaries for fast interaction and data retrieval.

Selected Area Only — Select a piece of text to spell check by using your mouse or keyboard. You can spell check only the selected area instead of the whole text.

Control Suggestions — Specify the maximum number of suggestions to be returned by the spelling engine for each spelling mistake.

Keep Ignoring — If you click Ignore All to ignore all occurences of a word it will keep ignoring them until you refresh the page.

PostBack on OK — Return to server when the user clicks the OK button on the spell check dialog box bypassing a changed flag. You can see any changes made to the original text during spell checking.

Inside Other Controls — Insert the UltimateSpell control into other server controls such as a datagrid or a user control.

Custom Style — Change the style of the spell button, misspelled word style and spell check dialog box based on your design preferences.

AJAX Enabled — Spell check very long text by sending small blocks of text to server using AJAX techniques without refreshing the page.
