Query :

create database sss
go
use sss
go
create table ss_imgsample(imgid int identity(1,1),imgname varchar(150),imgfile image,primary key(imgid))
go
select * from ss_imgsample
go

Design :

<div style="height: 361px">
file name :
<asp:TextBox ID="TextBox1" runat="server">
<br />
choose the image file
<br />
<asp:FileUpload ID="FileUpload1" runat="server" />
<br />
<br />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="click" />
<br />
<br />
<asp:Label ID="Label1" runat="server">
<br />
<asp:Label ID="Label2" runat="server">
<br />
<br />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="imgid" DataSourceID="SqlDataSource1">
<columns>
<asp:BoundField DataField="imgid" HeaderText="imgid" InsertVisible="False"
ReadOnly="True" SortExpression="imgid" />
<asp:BoundField DataField="imgname" HeaderText="imgname"
SortExpression="imgname" />

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:sssConnectionString %>"
SelectCommand="SELECT * FROM [ss_imgsample]">
</div>

Coding :

using System.Data.SqlClient;

SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=sss;Integrated Security=True");
SqlCommand cmd = new SqlCommand();

protected void Button1_Click(object sender, EventArgs e)
{
attach();
}
protected void attach()
{
lbl_attachments.Text = "";
try
{
if (FileUpload1.HasFile)
{
Label1.Text = fileupload_img.FileName;
FileUpload1.SaveAs(Server.MapPath("~/Tempfiles/" + Label1.Text));
cmd = new SqlCommand("insert into ss_imgsample values('" + TextBox1.Text + "','" + FileUpload1.PostedFile.FileName + "') ", con);
if(cmd.EndExecuteNonQuery()>0)
{
Label1.Text="inserted";
}else{
Label1.Text="not done";
}

}
else
{
Label1.Text = "No file selected";

}
}
catch (Exception ex)
{ Response.Write(ex.Message); }

}

--------------------------------------

we have to insert the value in to database and show the value in grid view.
if u click on the grid view image then the page is redirected ti new page and displays the file name and image.

waiting for ur response.

To store Image in Sql server use following code:

Stream imgStream = FileUpload1.PostedFile.InputStream;
            BinaryReader imgBinary = new BinaryReader(imgStream);
            Byte[] bytes = imgBinary.ReadBytes((Int32)imgStream.Length);
            imgBinary.Close();
            imgStream.Close();
            string imageName = FileUpload1.PostedFile.FileName;
            string imgBinary = Convert.ToBase64String(bytes);
//Store the imageName and imgBinary in the database. Make sure the column data type for imgBinary is Image.

Now to retrieve and show the stored image from database, create new aspx page and put below code in Page_Load event.

string imgName = Request.QueryString["ImageName"].ToString();
            string sql = "Select Img from TestImage where ImgName='" + imgName + "'";
            SqlCommand myCommand = new SqlCommand(sql, con);
            con.Open();
            object objImage = myCommand.ExecuteScalar();
            Response.Clear();
            Response.ContentType = "image/jpeg";
            Response.BinaryWrite((byte[])objImage);
            Response.End();
