The built-in spell dialog checks the list when it finds a misspelled word. If a match is found, the misspelled word is replaced with the corresponding list entry. The as-you-type mechanism looks for matches whenever the user types a character that is not a letter or a digit. If a match is found, the text is replaced with the corresponding list entry.

Use the AutoReplaceList property to spell-check a list of words, and if a match is found on the list then the misspelled word is replaced with the corresponding list entry as-you-type.

For example, you can monitor spelling on a Windows.Forms.RichTextBox control using this list. To see this feature in action, complete the following steps:

1. From the Toolbox, add the SpellChecker component and RichTextBox control to your form.

   Note that the C1SpellChecker component will appear below the form, not on it.

2. Select the RichTextBox, and set the following properties:
   • Dock property to Fill.
   • SpellChecking on C1SpellChecker1 property to True.
3. Enter the following in your source code to declare the directive for the C1.Win.C1SpellChecker:
   • CS
   • VB

   • CS

   using C1.Win.C1SpellChecker;
   

   • VB

   Imports C1.Win.C1SpellChecker
   

4. Then double-click the RichTextBox and implement the following code in the body of the RichTextBox1_TextChanged event handler:
   • CS
   • VB

   • CS

   // Build AutoReplace list
   c1SpellChecker1.AutoReplaceList.Clear();
   c1SpellChecker1.AutoReplaceList.Add("becuase", "because");
   c1SpellChecker1.AutoReplaceList.Add("cant", "can't");
   c1SpellChecker1.AutoReplaceList.Add("recieve", "receive");
   c1SpellChecker1.AutoReplaceList.Add("teh", "the");
   c1SpellChecker1.AutoReplaceList.Add("wont", "won't");
   // Activate as-you-type spell-checking on the RichTextBox
   c1SpellChecker1.SetActiveSpellChecking(richTextBox1, true);
   

   • VB

   ' Build AutoReplace list
   C1SpellChecker1.AutoReplaceList.Clear()
   C1SpellChecker1.AutoReplaceList.Add("becuase", "because")
   C1SpellChecker1.AutoReplaceList.Add("cant", "can't")
   C1SpellChecker1.AutoReplaceList.Add("recieve", "receive")
   C1SpellChecker1.AutoReplaceList.Add("teh", "the")
   C1SpellChecker1.AutoReplaceList.Add("wont", "won't")
   ' Activate as-you-type spell-checking on the RichTextBox
   C1SpellChecker1.SetActiveSpellChecking(RichTextBox1, True)
   

   This code builds the following list using the AutoReplaceList.Add method:

   Misspelled word	Correction word
   because	because
   cant	can't
   receive	receive
   the	the
   wont	won't

   Then it activates as-you-type spell-checking on the RichTextBox control using the SetActiveSpellChecking method.

Run the application and observe the following:
