Hello,
I have a pdf that was created using Acrobat Pro DC. This pdf has many form fields on it. I am looking for a way to submit the form field data back to an ASP.NET Webmethod behind the scenes when a button is clicked. The user could then continue filling out the form, saving as many times as they want. This would be a lot like using ajax to post data to a webmethod.
Currently I am converting the pdf into a memorystream and then adding the submit button with the following code:
Dim doc As New Aspose.Pdf.Document(pdfStream)
Dim formEditor As New Aspose.Pdf.Facades.FormEditor(doc)
formEditor.AddSubmitBtn("btnSave", 1, "Save", buttonAction, 400, 20, 500, 50)
formEditor.Save(pdfStream)
buttonAction would be something like "https://localhost/somepage.aspx/webmethod"
This is the type of webmethod that is being called:
Public Shared Function SavePDFData() As String
Try
'Save data to database
Return "Success"
Catch ex As Exception
Return "Failed"
End Try
End Function
What happens now is that when the button is clicked the pdf does in fact post the data to the page (I am using Fiddler to see this) but I don't see any indication that it ever got to the webmethod on the page but instead tries to open "https://localhost/somepage.aspx/webmethod".
I'm not sold on using a webmethod for this so if there is a better way I am more than willing to try it as long as the end result is not redirecting to another page.
