Provides real-time spell checking functionality to text editing controls, including TextBox and RichTextBox.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public sealed class SpellCheck
You cannot directly create an instance of this class in XAML.

When this spell checker is enabled, misspelled words are underlined by a red squiggly line.

The following example shows how to enable real-time spell checking in a TextBox by using the IsEnabled property of the SpellCheck class.

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    <TextBox SpellCheck.IsEnabled="True" Name="myTextBox"></TextBox>

using System;
using System.Windows;
using System.Windows.Controls;

namespace SDKSample
    public partial class SpellCheckExample : Page
        public SpellCheckExample()
            StackPanel myStackPanel = new StackPanel();

            //Create TextBox
            TextBox myTextBox = new TextBox();
            myTextBox.Width = 200;

            // Enable spellchecking on the TextBox.
            myTextBox.SpellCheck.IsEnabled = true;

            // Alternatively, the SetIsEnabled method could be used 
            // to enable or disable spell checking like this: 
            // SpellCheck.SetIsEnabled(myTextBox, true);

            this.Content = myStackPanel;
