I have created a custom page where I supply a search query string (k=Param:Value) that only have a results webpart (no search form). It is intended to be called from our CRM (Dynamics) in the form
http://sp2013-portal/show_documents.aspx?k=ClientId:123 so we can display all the documents associated with this client. All this is working fine.
I then added a button on my page to upload the document into the drop off library using the builtin upload.aspx form. All this is working fine.
What I would like to do is pass my original parameter ClientId:123 to the drop off library so it can automatically feed the ClientId metadata. Is that possible?
