RichTextBox.GetSpellingError Method

Returns a SpellingError object associated with any spelling error at a specified position in the contents of the RichTextBox.

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

member GetSpellingError : 
        position:TextPointer -> SpellingError 

Parameters

position
Type: System.Windows.Documents.TextPointer
A TextPointer that specifies a position and logical direction that resolves to a character to examine for a spelling error. Use the LogicalDirection property of this TextPointer to specify the direction of the character to examine.

Return Value

Type: System.Windows.Controls.SpellingError
A SpellingError object containing the details of the spelling error found at the character indicated by position, or a null reference (Nothing in Visual Basic) if no spelling error exists at the specified character.

A TextPointer like position usually specifies a position between two characters. Use the LogicalDirection property of position to specify which character to examine.

By default, when you enable spell checking in an editing control like TextBox or RichTextBox, you get spell-checking choices in the context menu. For example, when users right-click a misspelled word, they get a set of spelling suggestions or the option to Ignore All. However, when you override the default context menu with your own custom context menu, this functionality is lost, and you need to write code to reenable the spell-checking feature in the context menu. The following example shows how to enable this on a TextBox.

The following example shows the Extensible Application Markup Language (XAML) that creates a TextBox with some events that are used to implement the context menu.


<Page x:Class="SDKSample.SpellerCustomContextMenu"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Loaded="OnWindowLoaded">

  <TextBox
    Name="myTextBox" 
    TextWrapping="Wrap"
    SpellCheck.IsEnabled="True"
    ContextMenuOpening="tb_ContextMenuOpening">
    In a custum menu you need to write code to add speler choices
    because everything in a custom context menu has to be added explicitly.
  </TextBox>

</Page>


The following example shows the code that implements the context menu.

No code example is currently available or this language may not be supported.

The code used for doing this with a RichTextBox is similar. The main difference is in the parameter passed to the GetSpellingError method. For a TextBox, pass the integer index of the caret position:

spellingError = myTextBox.GetSpellingError(caretIndex);

For a RichTextBox, pass the TextPointer that specifies the caret position:

spellingError = myRichTextBox.GetSpellingError(myRichTextBox.CaretPosition);
