How to replace all inlineUIContainers in RadDocument by SpanBoxs

[york]

Hi,
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);
radRichTextBox1.Insert(text);

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

Thanks,
York

Hello Christian, York,
You can achieve this as follows:

this.radRichTextBox.BeginUndoGroup();

foreach (var inlineUIContainer in this.radRichTextBox.Document.EnumerateChildrenOfType<InlineUIContainer>().Reverse().ToList())
{
    this.radRichTextBox.Document.CaretPosition.MoveToStartOfDocumentElement(inlineUIContainer);
    this.radRichTextBox.Delete(false);
    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.
