Try this protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["ImageID"] != null) { string strQuery = "select Name, ContentType, Data from tblFiles where id=@id"; SqlCommand cmd = new SqlCommand(strQuery); cmd.Parameters.Add("@id", SqlDbType.Int).Value = Convert.ToInt32 (Request.QueryString["ImageID"]); DataTable dt = GetData(cmd); if (dt != null) { Byte[] bytes = (Byte[])dt.Rows[0]["Data"]; Response.Buffer = true; Response.Charset = ""; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = dt.Rows[0]["ContentType"].ToString(); Response.AddHeader("content-disposition", "attachment;filename=" + dt.Rows[0]["Name"].ToString()); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); }
