        DataTable table = new DataTable();
        adapter.Fill(table);
        return table;
    }
 
    private DataTable GetSpecificVideo(object i)
    {
        string connectionString = ConfigurationManager.ConnectionStrings["uploadConnectionString"].ConnectionString;
        SqlDataAdapter adapter = new SqlDataAdapter("SELECT Video, ID FROM Videos WHERE ID = @id", connectionString);
        adapter.SelectCommand.Parameters.Add("@id", SqlDbType.Int).Value = (int)i;
        DataTable table = new DataTable();
        adapter.Fill(table);
        return table;
    }
    protected void ButtonShowVideo_Click(object sender, EventArgs e)
    {
        Repeater1.DataSource = GetSpecificVideo(2);
        Repeater1.DataBind();

i have used videohandler for displaying video, and i think it cannot get video's id
here is my videohandler code

public void ProcessRequest (HttpContext context) 
    {
        string connectionString = ConfigurationManager.ConnectionStrings["uploadConnectionString"].ConnectionString;
 
        SqlConnection connection = new SqlConnection(connectionString);
        SqlCommand cmd = new SqlCommand("SELECT Video, Video_Name FROM Videos WHERE ID = @id", connection);
        cmd.Parameters.Add("@id", SqlDbType.Int).Value = context.Request.QueryString["id"];
        try
        {
            connection.Open();
            SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.Default);
            if (reader.HasRows)
            {
                while (reader.Read())
                {
                    context.Response.ContentType = reader["Video_Name"].ToString();
                    context.Response.BinaryWrite((byte[])reader["Video"]);
                }
            }
        }
        finally
        {
            connection.Close();
        }
    }
