Question

I am working on a nested repeater. My issue seems to be at the moment, that when I execute my SQL command that no data is returned to the data reader. Even when I run the exact same query (Copy and Pasted) into SQL Server.

My noteDrClient reader does not contain data, it does however know that there are 5 columns in the table. I have no idea what to do at this point or why no data is being passed into the data reader. Can anyone see an obvious problem?

  SqlConnection con = new SqlConnection("Data Source=***;Initial Catalog=*;User   ID=*;Password=*;Integrated Security=False;MultipleActiveResultSets=true;");

Above is my connection string. Please notice that I have Multiple Active Result Sets set to true. I did this because I kept getting errors about my data reader being open, even though it was closed.

   protected void rptList_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        RepeaterItem item = e.Item;
        if ((item.ItemType == ListItemType.Item) ||
            (item.ItemType == ListItemType.AlternatingItem))
        {

            System.Data.Common.DbDataRecord rd = (System.Data.Common.DbDataRecord)e.Item.DataItem;

            Repeater nestedRepeater = e.Item.FindControl("NotesRepeater") as Repeater;
            string FID = rd[0].ToString();


            using (cmd2 = new SqlCommand("SELECT * FROM notes WHERE FID = 1356;", con)) ;

            SqlDataReader noteDrClient = cmd2.ExecuteReader();  //no data is being filled to the data reader... even though this command pulls data in SQL Server Management Studio.

            if (noteDrClient.Read()) {   //bind the repeater if there is data to bind
                    nestedRepeater.DataSource = noteDrClient;
                    nestedRepeater.DataBind();
            }

            noteDrClient.Close();                                   




        }

You’re using statement is disposing the SqlCommand before you have a chance to use it. Additionally, you’re attempting to bind to a DataReader. Get the results from the data reader into a collection of “Note” entities and bind to the collection instead.

        using (SqlCommand cmd2 = new SqlCommand("SELECT * FROM notes WHERE FID = 1356;", con))
        {

            using(SqlDataReader noteDrClient = cmd2.ExecuteReader())
            {

                while (noteDrClient.Read()) 
                {   
                    Note n = new Note();
                    ... get note from data reader
                    notes.Add(n); // add note to collection
                }
            }
        } 

        // bind child
        nestedRepeater.DataSource = notes;       
        nestedRepeater.DataBind();
