implement spell checker for whole document

Question

Currently I am applying spell checker for my document editor as follows:

    this.serviceLink = this.baseUrl + '/api/syncfusion/';
    this.documentContainer.documentEditor.spellChecker.languageID = 2057; //LCID of "en-GB";
    this.documentContainer.documentEditor.spellChecker.removeUnderline = false;
    this.documentContainer.documentEditor.spellChecker.allowSpellCheckAndSuggestion = true;
    this.documentContainer.documentEditor.spellChecker.enableOptimizedSpellCheck = true;

This works great but a call is made to the server to check spelling after every (I think) space is detected.

This creates a heavy call load on the api.

What I would like to do is have a button on the toolbar to spell check the entire document and have the option to toggle red-squiggle-underlining.

How can I do this?

Hi Bob,    

Sorry for the inconvenience caused. We are not able reproduce the reported issue. 

Please find the behaviour of the spell check: 

1. When "enableOptimizedSpellCheck" is set to true it will call the page-by-page spell check when a document is opened.2. When we type a word after opening a document spell check for each word only be triggered. 

We are prepared sample based on your requirement kindly check the below sample link.

Server side:

Please find the code changes in DocumentEditorController.cs and Startup.cs files.  

Note:  please find the Dictionary files in the name of Data. 

Please let us know if you have any questions.

Hi Bob, 

Syncfusion Greetings! 

Document editor provides option to enable/disable the spellcheck and to toggle the render underline in status bar. 

  

Document provides API to toggle the red underline and spellcheck. 





containerInstance.documentEditor.spellChecker.removeUnderlinecontainerInstance.documentEditor.spellChecker.enableSpellCheck 
 
But UI is not refreshed when setting the above API. We have logged a bug task for this. Fix will be included in our upcoming EJ2 patch release which is tentatively scheduled on Aug 12th, 2020. Once included, will update you. Fix status can be tracked from below link.

Hi Harini,I found the spell check drop down, thanks.However, the problem is not the availability of this functionality but the load on the server when spell check is enabled.If I have hundreds of users editing documents at the same time the idea of calling a spell check for every word as it is typed is simply too great.Is there any way the drop down could be used to fire off a single spell check operation for all content in the document?Cheers,Bob

Hi Bob,  
 
Regarding Is there any way the drop down could be used to fire off a single spell check operation for all content in the document? 
 
We don’t have support to fire off a single spell check operation for all content in the document 
 
But, We do have support to fire off a single spell check operation per page. You can achieve this by using enableOptimizedSpellCheck API. 
 
https://ej2.syncfusion.com/angular/documentation/api/document-editor/spellChecker/#enableoptimizedspellcheck-code-classlanguage-textbooleancode 
 
Alternatively, You can enable/disable the spell check feature to trigger spell check for all the content in the document

Hello I have enabledOtimizedSpellcheck functionality enabled, but it is not working, additionally, the spelling drop-down menu does not allow me to enable or disable the function, it is always enabled.

As it stands, it continues to send many requests to time. Am I missing any settings?

Hi, 

enableOptimizedSpellCheck allows to spell check page by page when document loading. We suspect the issue that your languageId is not matched with server side languageId. Can you please check it to work spell check functionality? 

To optimize spell check request, we have already logged the feature request to request spell check based on time interval. We will include it in any of our upcoming release. 

You can track the status of this feature through below feedback link:

the general correction works, what is not working is SpeelcheckByPage. It is enabled from the code.

Kurthis Banu Abdul Majeeth · Answer

Hi Bob, 

In our end spellcheckByPage has been trigger properly when “enableOptimizedSpellCheck” set to true. But spellcheck (spellcheck by word) also trigger each time for every single word when loading document. Currently, we are validating this behaviour. We will update further details by May 11,2021.
