It works fine with the same code but for pdf provider.
Even more strange if I export first as pdf and then as docx it works... any idea why?

[Marco]

Any solution or explanation for this behaviour?
What libraries should be set on xaml and on c#?

Hi Marco,

After the document is first created or imported, it needs to be measured and arranged before it can be exported. It is automatically measured and arranged when you show it in a RadRichTextBox, but if you are only using it in code-behind, you need to manually invoke the following function before the export:

private void MeasureAndArrangeInDefaultSize(RadDocument document)
{
    document.Measure(RadDocument.MAX_DOCUMENT_SIZE);
    document.Arrange(new RectangleF(PointF.Empty, document.DesiredSize));
}

Please let us know if that does not solve the problem.
