this.radTextBox1.Text = "This iss a samplee text thaat shows incorrect words";
this.radSpellChecker1.AutoSpellCheckControl = this.radTextBox1;

TextBoxSpellChecker textSpellChecker = this.radSpellChecker1.GetControlSpellChecker(typeof(RadTextBox)) as TextBoxSpellChecker;

Regex wordParser = new Regex(@"[\p{L}\p{N}\p{M}]+(?:[-.'´_@][\p{L}|\p{N}|\p{M}]+)*", RegexOptions.Compiled);
Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker checker =
    textSpellChecker.SpellChecker as Telerik.WinControls.SpellChecker.Proofing.DocumentSpellChecker;

foreach (Match word in wordParser.Matches(this.radTextBox1.Text + ""))
{
    if (!checker.CheckWordIsCorrect(word.Captures[0].Value))
        Console.WriteLine(word.Captures[0].Value);
}



Me.RadTextBox1.Text = "This iss a samplee text thaat shows incorrect words"
Me.RadSpellChecker1.AutoSpellCheckControl = Me.RadTextBox1

Dim textSpellChecker As TextBoxSpellChecker = TryCast(Me.RadSpellChecker1.GetControlSpellChecker(GetType(RadTextBox)), TextBoxSpellChecker)

Dim wordParser As Regex = New Regex("[\p{L}\p{N}\p{M}]+(?:[-.'´_@][\p{L}|\p{N}|\p{M}]+)*", RegexOptions.Compiled)
Dim checker As Proofing.DocumentSpellChecker = TryCast(textSpellChecker.SpellChecker, Proofing.DocumentSpellChecker)

For Each word As Match In wordParser.Matches(Me.RadTextBox1.Text & "")

    If Not checker.CheckWordIsCorrect(word.Captures(0).Value) Then
        Console.WriteLine(word.Captures(0).Value)
    End If
Next
