Adding controls to panel

The section of code
event_list_panel.Controls.Add(d_event_title[rowCount]);
event_list_panel.Controls.Add(d_event_type[rowCount]);
event_list_panel.Controls.Add(d_event_location[rowCount]);
event_list_panel.Controls.Add(d_event_remove[rowCount]);
is only adding the first item in the list of four.

Why?
What am I missing?

private void mainForm_Load(object sender, EventArgs e)
        {
            int _x = 100;
            int _y = 100;
            int rowCount = 0;
            int screenWidth = (this.ClientSize.Width - (_x*2));
 
            ADODB.Recordset rs = new ADODB.Recordset();
            Connection = new ADODB.Connection();
            Connection.Open("NKTConnections", null, null, 0);
            string sql = "SELECT d.event_id, d.event_title, d.event_type, d.event_location FROM events_calendar_data d, events_calendar_datetime t where d.event_id = t.event_id ORDER BY t.event_date DESC, d.event_title;";
            rs.CursorLocation = CursorLocationEnum.adUseClient;
            rs.Open(sql, Connection, CursorTypeEnum.adOpenForwardOnly, LockTypeEnum.adLockReadOnly, 0);
            int _recordCount = rs.RecordCount;
 
            Label[] d_event_title = new Label[_recordCount];
            Label[] d_event_type = new Label[_recordCount];

How do you know?, maybe them are present but with null string?

ASKER

because I did a lot of testing to be sure.

if I do this

//event_list_panel.Controls.Add(d_event_title[rowCount]);
event_list_panel.Controls.Add(d_event_type[rowCount]);
event_list_panel.Controls.Add(d_event_location[rowCount]);
event_list_panel.Controls.Add(d_event_remove[rowCount]);
then the next one shows but not the following two don't show,

if I do this.

//event_list_panel.Controls.Add(d_event_title[rowCount]);
//event_list_panel.Controls.Add(d_event_type[rowCount]);
event_list_panel.Controls.Add(d_event_location[rowCount]);
event_list_panel.Controls.Add(d_event_remove[rowCount]);
then the first availble one shows but not the last, and if I comment out the first three then the last one shows, I've even reordered them to see what happens, and always the first one in the list is added but not the others.

have you tried with AddRange?

I've looked into it, but I don't know enough about it, I was having trouble finding good examples with what I needed.
