How to view PDF file before downloading

Abraham Olatubosun

Dear code master, I believe you all doing well.

I am writing an application where I uploaded a pdf file as varbinary(Max) this work file.

I want the user to view the pdf file first before downloading, when I run the application and click the button I get the pdf viewer inline but it display’s “Failed to load PDF document”.

My code is shown below:

var DT = new DataTable();
DT = ConnectAll.DownloadFile(TextBox1.Text.Trim());
foreach (DataRow r in DT.Rows)
{
byte[] myFile = (byte[])r["docu"];
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "inline;filename=MME.pdf");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.BinaryWrite(myFile);
Response.End();
}

Can anybody help me ?

Thank you all

Many thanks Darjean, yes my application is ASP.NET using C# meaning it is a web aplication, however, i will like to stress that the pdf file i am trying to view is already stored in the database not in a folder. So we want to view the pdf file before downloading it.

thanks i appreciate any other sollution to this.
