How to download notes in Online CRM 2015 using asp.net

(0) ShareShare
ReportReport
Posted on by Arun07Kumar

I am developing a web form in asp.net to provide links to every note in my CRM online account, so that by clicking those links I can see/download those files(notes) on my computer system.

one option that I was considering is to create the copy of the files on my local server and then giving that link to the users, but that will create duplicacy. ( more time complex when no. of files are large and their size too)

Can you help me to get direct links to those files?

    Hi Arun,

    This is really easy to do.

    Notes are stored in the annotation entity, and the content of the file attached is in the documentbody field, which is a string. To get the file as a byte[] for your users to consume it, convert it using:

    byte[] fileContent = Convert.FromBase64String(this.documentbody);

    If you want to let the user download the note from a .Net web application, let them click on the note they want, get the file contents, then write it to the response like this:

    byte[] fileContent = Convert.FromBase64String( {the notes document body attribute });

this.Page.Response.Clear();
this.Page.Response.AddHeader("Content-Disposition", "attachment; filename=" + "TheFileName.ext");
this.Page.Response.AddHeader("Content-Length", fileContent.Length.ToString());
this.Page.Response.ContentType = "application/octet-stream";
this.Page.Response.BinaryWrite(fileContent);
this.Page.Response.Flush();
this.Page.Response.End();


    If this helps I'd appreciate if you would mark this as a Verified answer.

    Thanks,

      Aiden
