    If I use Ctrl-A to select all the data in the RichTextBox, and then use Document.Delete to delete it, I get an InvalidCastException. The exception is "Unable to cast object of type 'Telerik.Windows.Documents.Layout.TableLayoutBox' to type 'Telerik.Windows.Documents.Layout.ParagraphLayoutBox'.  If I select just a portion of the text in the RichTextBox and then use Document.Delete() to remove it, I have no problem.  Is there some other method that should be used to delete text that has been selected with Ctrl-A?

    Hello Jim,

    The issue you are facing is a know one and has been discussed in this forum thread. Basically, you can solve it in one of the following ways:
    • Use the RadRichTextBox.Delete() method instead.
    • Create a RadDocumentEditor that will mimic a RadRichTextBox containing your document and call its Delete() method.

    Let us know if you have other questions.
