Is there a way to insert the PDF widget after presigning?

Thank you for contacting us.

Could you clarify what do you mean by "presigning"?

Of course, sorry I was not clear.

As in the ASPNet_Distributed example the first step is to pre sign the document. This is what I mean with "presigning".

The second step is to complete the signature. Is it posible to insert or change the PDF widget in this stage?

Hello Kees,

I am afraid it is not possible, sorry. The body of the signature widget is included into the hash calculation procedure on the pre-signing stage, so altering (or inserting) it on the finalization stage invalidates the signature.

No, it is not possible. As signature widget should be signed.
As I understand, you want to include a user info into a signature widget, in this case you need to submit a public certificate or custom info in the first step (in the sample it is "Default" aspx file).
