I need to determine if document is empty, even if the document was just created in other parts of the code. The code below throws the exception. If the commented lines are uncommented then the exception is not thrown. I could work around the problem also by carrying a flag to tell me if document was just created (and not call GetStatisticsInfo in that case). Is this exception a bug? Is there a smarter or more elegant way to determine if document is empty?
var d = new RadDocument();//var p = new Telerik.WinForms.Documents.FormatProviders.Rtf.RtfFormatProvider();//d = p.Import(p.Export(d));var s = d.GetStatisticsInfo();

I just stumbled upon RadDocument.IsEmpty property. It seems to be exactly what I was looking for, because I don't need statistics, but just this one information, and it does not throw an exception on brand new document. Should I use this one?

Hello Mihajlo,
Yes, this property can be used for this as well. It does a similar thing and checks if there are sections with content in the document.
