Hello,
You can define a OnAfterSave method, which is triggered after the BizForm is saved (the bizform web part is located in the CMSWebParts\BizForms\bizform.ascx.cs file):
For example:
protected void viewBiz_OnAfterSave()
{
//...here you can use the
ResponseRedirect(Url) method
}
To get the URL you can create links in the following format:
www.mydomain.com/bizformpage?id=PDF_id
In your case can the PDF_id be the GUID of the file from the system. To get this id you can either create a database query for it (it's located in the CMS_Attachment table under the AttachmentGUID column) or you can use the CMS.FileManager.AttachmentManager (our API reference can be found
here). Creating a link to the file should help this
documentation.
If you need help with anything else, please let me know on which part you need more information.
Best regards,
Boris Pocatko
