You write a SELECT query and get the URL back out of the database.

Use this code in your menthod:

C#

string strFilePath = @"\Files\test.pdf";
                Response.ContentType = "jpg/doc/pdf";
                Response.AddHeader("Content-Disposition", "attachment;filename=\"" + strFilePath + "\"");
                Response.TransmitFile(Server.MapPath(strFilePath));
                Response.End();

Note: strFilePath is the virtual path.
Server.MapPath() will return the physical path using your specified virtual path.

Hi...

thank u for ur replay.
am also find the solution to it like.
in button event:
con = new MySqlConnection(cs);
cmd = new MySqlCommand("select * from files", con);
da = new MySqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);

string path = Server.MapPath("~/PDF/" + ds.Tables[0].Rows[0]["FileName"].ToString());
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(path);

if (buffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", buffer.Length.ToString());
Response.BinaryWrite(buffer);
}
thank u.
