how to set default image for file upload control

Example
---------------------
1.step 1 create table in sql(2005/2008) like below.

in sql
--------
Id  = varchar(50)
Image=image

2.step2 design .aspx form like below


in .aspx
-----------
<div>

    <table align="center"><tr><td>
        <asp:Label ID="lblid" runat="server" Text="ID"></asp:Label></td><td>
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td></tr>
            <tr><td>Choose File</td><td><asp:FileUpload ID="FileUpload1" runat="server" />
        </td></tr>
               <tr><td></td><td>
                   <asp:Button ID="Button1" runat="server"
            Text="Submit" onclick="Button1_Click" /></td></tr>
            </table>

         <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
        <Columns>
        <asp:TemplateField HeaderText="ID">
        <ItemTemplate>
            <asp:Label ID="Label4" runat="server" Text='<%#Eval("id") %>'></asp:Label>
        </ItemTemplate>
        </asp:TemplateField>

        <asp:TemplateField>
        <ItemTemplate>
            <asp:Image ID="Image1" runat="server" ImageUrl='<%#"Handler2.ashx?ID="+Eval("id")

%>'/>
        </ItemTemplate>
        </asp:TemplateField>
        </Columns>
        </asp:GridView>
    </div>


3.step3 add one Handler.ashx to your project
4.here clearly observe in .aspx ID(ImageUrl='<%#"Handler2.ashx?ID) and in .ashx file( string id =

context.Request.QueryString["ID"];)  will keep same

in Handler2.ashx
----------------------


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;

namespace _3tier
{
    /// <summary>
    /// Summary description for Handler2
    /// </summary>
    public class Handler2 : IHttpHandler
    {
        string cs =

ConfigurationManager.ConnectionStrings["msdbConnectionString"].ConnectionString;
        public void ProcessRequest(HttpContext context)
        {
            string id = context.Request.QueryString["ID"];
            SqlConnection con = new SqlConnection(cs);
            string query = "select * from img Where id=" + id;
            con.Open();
            SqlCommand cmd = new SqlCommand(query, con);
            SqlDataReader dr;
            dr = cmd.ExecuteReader();
            dr.Read();
            context.Response.BinaryWrite((Byte[])(dr[1]));
            context.Response.End();
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}


5.step 5 write the code in .aspx.cs like below

.aspx.cs
------------

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;

namespace _3tier
{
    public partial class WebForm2 : System.Web.UI.Page
    {
        string cs =

ConfigurationManager.ConnectionStrings["msdbConnectionString"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            if (FileUpload1.HasFile)
            {
                int length = FileUpload1.PostedFile.ContentLength;
                byte[] imgbyte = new byte[length];
                HttpPostedFile IMG = FileUpload1.PostedFile;
                IMG.InputStream.Read(imgbyte, 0, length);
                SqlConnection con = new SqlConnection(cs);
                string query1 = "insert into img(id,image) values(@id,@image)";
                SqlCommand cmd = new SqlCommand(query1, con);
                con.Open();
                cmd.Parameters.Add("@id", SqlDbType.VarChar, 50).Value = TextBox1.Text;
                //cmd.Parameters.Add("@Name", SqlDbType.VarChar, 50).Value = TextBox2.Text;
                cmd.Parameters.Add("@image", SqlDbType.Image).Value = imgbyte;
                cmd.ExecuteNonQuery();
                string query2 = "select * from img";
                SqlDataAdapter da = new SqlDataAdapter(query2, con);
                DataSet ds = new DataSet();
                da.Fill(ds);
                GridView1.DataSource = ds;
                GridView1.DataBind();
                con.Close();

            }
            TextBox1.Text = string.Empty;
        }
    }
}
