ASPxHtmlEditor allows end-users to check the spelling of its content by using the Check Spelling dialog.
The dialog can be invoked in design view in the following ways.
If the text contains spelling errors, the dialog allows you to view these errors and either correct or ignore them.
After the entire text has been scanned, the following window is shown.
If ASPxHtmlEditor contains the Check Spelling button, the built-in browser spell check feature is disabled.
You can customize dialog settings programmatically by using the HtmlEditorDefaultDialogSettings.CheckSpellingDialog property; or by using the design-time ASPxHtmlEditor Designer.
The spell checking functionality can be customized by using the ASPxHtmlEditor.SettingsSpellChecker property.
