ISpellCheckService.MaxSuggestionCount Property

Specifies the maximum number of suggestions the context menu should display.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

int MaxSuggestionCount { get; }

Property Value

Type	Description
Int32	The maximum number of suggestions.

Remarks

Implement the GetSpellingSuggestions(String) method to generate suggestions on how to replace a misspelled word. The Rich Text Editors displays the suggested words and phrases in the context menu. If the GetSpellingSuggestions(String) method returns an empty array, the context menu displays No suggestions.

The MaxSuggestionCount property specifies the maximum number of suggestions the context menu should display. For instance, if you set this property to 3, the context menu displays up to 3 suggestions. If the GetSpellingSuggestions(String) method generates more than 3 suggestions, the context menu displays only the first 3 suggestions from the array.

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();
    }
}
