Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

CultureInfo Culture { get; set; }

Property Value

Type Description
CultureInfo

An open document’s culture.

Remarks

The Rich Text Editor’s DocumentCulture property specifies an open document’s culture and allows you to change it at runtime. Inside a custom spell check service’s code, use the Culture property to get the current document culture. Depending on this culture, you can change the behavior of your service.

The following code snippet implements an ISpellCheckService interface and check spelling only for documents in English:

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();
    }
}
