We are also interested in this feature.
This is a ver interesting feature for e-billing. In some countries like Spain, the seller should make an XML, sign it and, optionally, attach the XML into a signed PDF.
We've been testing several reporting tools, and we think that Telerik's solution is the solution with best performance and rendering. However, other reporting solutions are currently shipping with PDF attachment and signature. For e-bussiness software solutions this is a BASIC requeriment and we can't choose Telerik as we want.
Please, include this functionality to your product.
We might buy now the "Premium Collection" if Telerik announce this features for the next Q1 2010 release and confirms it to us.
Thank you so much.
