# Dialog Boxes

## Content



When you call the [CheckControlAsync](/componentone/api/wpf/online-spellchecker/dotnet-framework-api/C1.WPF.SpellChecker.4.6.2/C1.WPF.SpellChecker.C1SpellChecker.CheckControlAsync.html) method, **SpellChecker for WPF and Silverlight** displays a dialog box that highlights each of the errors found in the control and allows the user to correct or ignore each error.

**SpellChecker for WPF and Silverlight** contains a built-in dialog box that is used by default. You can use the built-in dialog box as is, customize it, or replace it with your own custom version.
