protected void Page_Load(object sender, EventArgs e) {
    GridView1.DataSourceID = "";
    GridView1.DataSource = SqlDataSource1;
    GridView1.DataBind();
}

protected void btnSubmit_Click(object sender, EventArgs e) {
    string strImageName = txtImageName.Text.ToString();

    if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "") {
        byte[] imageSize = new byte[FileUpload1.PostedFile.ContentLength];
        HttpPostedFile uploadedImage = FileUpload1.PostedFile;
        uploadedImage.InputStream.Read(imageSize, 0, (int)FileUpload1.PostedFile.ContentLength);

        // Create SQL Connection
        SqlConnection con = new SqlConnection();
        con.ConnectionString = "Data Source=RND3" + "\\" + "SQLEXPRESS;Initial Catalog=SSSolutionFiles;Integrated Security=True";

        // Create SQL Command 
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "INSERT INTO Imagess(ImageName,Image)" + " VALUES (@ImageName,@Image)";
        cmd.CommandType = CommandType.Text;
        cmd.Connection = con;

        SqlParameter ImageName = new SqlParameter("@ImageName", SqlDbType.VarChar, 50);
        ImageName.Value = strImageName.ToString();
        cmd.Parameters.Add(ImageName);

        SqlParameter UploadedImage = new SqlParameter("@Image", SqlDbType.Image, imageSize.Length);
        UploadedImage.Value = imageSize;
        cmd.Parameters.Add(UploadedImage);
        con.Open();
        cmd.ExecuteNonQuery();
        con.Close();

        Label1.Text = "File Uploaded";

        GridView1.DataSourceID = "";
        GridView1.DataSource = SqlDataSource1;
        GridView1.DataBind();
        con.Close();
    }
