ISpellCheckService.AddToDictionaryEnabled Property

Specifies whether the Rich Text Editor displays the Add to dictionary command in the context menu.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

bool AddToDictionaryEnabled { get; }

Property Value

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

Remarks

Set this property to true to display the Add to dictionary command in the context menu. After a user clicks the command, the component passes the selected word to the AddToDictionary(String) method. Implement this method to save the word to your dictionary storage.

The example below demonstrates how to implement 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();
    }
}
