How to determine if current position is in editable range

[Chris]

How can I determine if the current caret position in a RadRichTextBox is within a range that is editable?

Thanks.

Hi Chris,

That depends on the approach you are using to restrict editing in your document. For example, if you are using the Document Protection feature and protection is enforced over the current document, here is how you can obtain the range where the caret is located and determine if the current user has rights to edit:

var range = this.radRichTextBox.Document.GetContainingAnnotationRanges<PermissionRangeStart>(this.radRichTextBox.Document.CaretPosition.GetCurrentInline()).First();
 if (range != null)
 {
     bool canEdit = this.radRichTextBox.ProtectionAuthenticationProvider.CanEdit(range.Info);
 }

I hope this is useful.
