    I try to replace all inlineUIContainers in RadDocument by SpanBoxes. I know how to do it at caretposition using Delete as,
    DocumentPosition currentPosition = radRichTextBox1.Document.CaretPosition;
    radRichTextBox1.Document.Delete(false, currentPosition);

    However I am not sure how to get documentpostion for each inlineUIContainers. I need help on this.

    Hello Christian, York,
    You can achieve this as follows:
    foreach (var inlineUIContainer in this.radRichTextBox.Document.EnumerateChildrenOfType<InlineUIContainer>().Reverse().ToList())
        this.radRichTextBox.InsertInline(new Span("InlineUIContainer was here."));
    this.radRichTextBox.EndUndoGroup("Replace all InlineUIContainers");
    The trick is to iterate the document elements in reversed order to avoid invalidating of the internal document indexes.
