Hi Jason,
This can be done by setting the BreakBehavior of the GraphicState object to AutoBreakBehavior.Cropping and passing this object to the DrawRTFText method as an argument.
props.BreakBehavior =AutoBreakBehavior.Cropping
//Draw RTF text at the specified Location.
pdfDoc.LastPage.Graphics.DrawRTFText(New PointF(10,50), rtf,props)
The way that RTF support is implemented is by rendering rich text to a vector image using the richtextbox control internally and then the vector image gets rendered into the PDF document. The BreakBehavior setting to the graphicstate object is for making the multipage image span across several pages.
Please take a look into the attached sample and let me know if you have any queries.
Thanks for your interest in Syncfusion products.
Best Regards,
Bhuvaneswari
