Question

I am facing a peculiar issue in my ADO.NET code. This is the table data that I am accessing from a repeater from the frontend.

1   get car cleaned             2012-02-14 08:32:25.643         NULL
2   submit tax documents        2012-02-14 08:33:04.610         NULL
3   photo copy all documents    2012-02-14 08:33:04.610         NULL

Data in the first row is not being displayed at all.

If I delete the rows 2 and 3, no data is being displayed in the repeater. I think the issue is with my ADO.NET code. Also, if I truncate the table completely, the page is loading forever as opposed to displaying the “No Data Found” message in the label.

protected void Page_Load(object sender, EventArgs e)
{
    txtNewTask.Focus();
    if (!IsPostBack)
    {
        GetTaskList();
    }
}

protected void GetTaskList()
{

    conn = new SqlConnection(cstr);
    getTasksCmd = new SqlCommand("select Name, CreationDate, CompletionDate from tasks", conn);

    try
    {
        using (conn)
        {
            conn.Open();
            using (reader = getTasksCmd.ExecuteReader())
            {
                while (!reader.Read())
                {
                    lblDbMsg.Text = "No Data Found!";
                }

                rptTaskList.DataSource = reader;
                rptTaskList.DataBind();

            }
        }
    }

    catch (Exception)
    {
        throw;
    }
}

Take out the while loop from your code:

        using (reader = getTasksCmd.ExecuteReader())
        {
            rptTaskList.DataSource = reader;
            rptTaskList.DataBind();
        }

Because you are calling SqlDataReader.Read() once, you are moving past the first record. Therefore, if you want to be able to retrieve all of the rows of data including the first, don’t call Read() at all.
