    Property Value

    Type Description
    Boolean

    true to display the Add to dictionary command; otherwise, false.

    The following code snippet implements an ISpellCheckService interface:

    using DevExpress.Blazor.RichEdit;
    using System.Collections.Generic;
    using System.Globalization;
    using System.IO;
    using System.Linq;
    
    public class MySpellCheckService : ISpellCheckService {
        public CultureInfo Culture { get; set; }
        public bool AddToDictionaryEnabled { get; }
        public int MaxSuggestionCount { get; }
        string PathToDictionary { get;}
        List<string> CorrectWords { get;}
    
        public MySpellCheckService(string path) {
            PathToDictionary = path;
            Culture = CultureInfo.InvariantCulture;
            AddToDictionaryEnabled = true;
            MaxSuggestionCount = 7;
            CorrectWords = File.ReadLines(PathToDictionary).ToList();
            CorrectWords.Sort();
        }
    
        public void AddToDictionary(string word) {
            if (Culture.TwoLetterISOLanguageName == "en") {
                word = word.ToLower();
                int placeToInsert = CorrectWords.BinarySearch(word);
                CorrectWords.Insert(placeToInsert, word);
                File.AppendAllText(PathToDictionary, word + '\n');
            }
        }
    
        public bool CheckWordSpelling(string word) {
            if (Culture.TwoLetterISOLanguageName == "en") {
                int index = CorrectWords.BinarySearch(word.ToLower());
                return (index >= 0);
            }
            return false;
        } 
    
        public string[] GetSpellingSuggestions(string word) {
            List<string> suggestions = new List<string>();
            // Generate suggestions and add them to the list
            return suggestions.ToArray();
        }
    }
