Description

The spell-checking functionality has a default dictionary that stores the words in the local IsolatedStorage (stores information per user). Additional information how to access it securely is available in the following help article: IsolatedStorage

This article demonstrates how you can extract the words added to the dictionary by the current user.

Solution

Since the new words are added to a custom separated dictionary stored in the application isolated storage file system, you can access it by using the following code snippet which demonstrates a sample approach with using a RadTextBox and a RadRichTextEditor control:

Extract words from the local dictionary

• C#
• VB.NET

Telerik.WinControls.UI.TextBoxSpellChecker textboxSpellChecker = this.radSpellChecker1.GetControlSpellChecker(typeof(RadTextBox)) 
    as Telerik.WinControls.UI.TextBoxSpellChecker;
Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker spellChecker = textboxSpellChecker.SpellChecker 
    as Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker;
spellChecker.SpellCheckingCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
Telerik.WinControls.SpellChecker.Proofing.RadIsolatedStorageCustomDictionary dictionary = 
    spellChecker.GetCustomDictionary(spellChecker.SpellCheckingCulture) as 
    Telerik.WinControls.SpellChecker.Proofing.RadIsolatedStorageCustomDictionary;
if (dictionary != null)
{
    foreach (string word in dictionary.Words)
    {
        //TODO add to the server
    }
}

Telerik.WinForms.Documents.Proofing.DocumentSpellChecker richTextSpellChecker = this.radRichTextEditor1.SpellChecker as 
Telerik.WinForms.Documents.Proofing.DocumentSpellChecker;
richTextSpellChecker.SpellCheckingCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
Telerik.WinForms.Documents.Proofing.RadIsolatedStorageCustomDictionary richTextDictionary =
    richTextSpellChecker.GetCustomDictionary(richTextSpellChecker.SpellCheckingCulture) as 
    Telerik.WinForms.Documents.Proofing.RadIsolatedStorageCustomDictionary;

if (richTextDictionary != null)
{
    foreach (string word in richTextDictionary.Words)
    {
        //TODO add to the server
    }
}

Dim textboxSpellChecker As Telerik.WinControls.UI.TextBoxSpellChecker = TryCast(Me.RadSpellChecker1.GetControlSpellChecker(GetType(RadTextBox)), TextBoxSpellChecker)
Dim spellChecker As Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker = TryCast(textboxSpellChecker.SpellChecker,  _
    Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker)
spellChecker.SpellCheckingCulture = System.Threading.Thread.CurrentThread.CurrentCulture
Dim dictionary As Telerik.WinControls.SpellChecker.Proofing.RadIsolatedStorageCustomDictionary = _
    TryCast(spellChecker.GetCustomDictionary(spellChecker.SpellCheckingCulture),  _
        Telerik.WinControls.SpellChecker.Proofing.RadIsolatedStorageCustomDictionary)

If dictionary IsNot Nothing Then

    For Each word As String In dictionary.Words
        Console.WriteLine(word)
        'TODO add to the server
    Next
End If

Dim richTextSpellChecker As Telerik.WinForms.Documents.Proofing.DocumentSpellChecker = TryCast(Me.RadRichTextEditor1.SpellChecker,  _
    Telerik.WinForms.Documents.Proofing.DocumentSpellChecker)
richTextSpellChecker.SpellCheckingCulture = System.Threading.Thread.CurrentThread.CurrentCulture
Dim richTextDictionary As Telerik.WinForms.Documents.Proofing.RadIsolatedStorageCustomDictionary = _
    TryCast(richTextSpellChecker.GetCustomDictionary(richTextSpellChecker.SpellCheckingCulture),  _
        Telerik.WinForms.Documents.Proofing.RadIsolatedStorageCustomDictionary)

If richTextDictionary IsNot Nothing Then

    For Each word As String In richTextDictionary.Words
        Console.WriteLine(word)
        'TODO add to the server
    Next
End If    

Once you have all the words that are added to the dictionary, you can perform any custom logic for storing these words to the server (e.g. store a file with these words to the server) or any appropriate storage for your precise case and read these words at a later moment. You can also define your custom RadIsolatedStorageCustomDictionary loaded from a file that contains the previously stored words and assign it to RadRichTextEditor.
