Gridview Nested ASP.NET Multiple values

I am writing a asp.net website and am running into an issue currently.

I have built a nested gridview following the following site - http://stackoverflow.com/questions/18533165/a-nested-gridview-example
I however am running into a little issue.

I altered the code to work how I wanted and am achiving somewhat of what I need.

Currently it shows in the parent gridview two columns - "Sender" and Recieved Date"
The drop down is pulling from the same sql table.

Whe I expand, it is showing me all records for that particular id not just the one pertaining to the specific entry.

I know what needs to be done but not how to implement it.

I want it to fill the drop down box with just the single records from SQL where the id matches, the sender matches and the recieved date matches.


here is my C#
 private static DataTable GetData(string query)
    {
        string strConnString = "Data Source=192.168.2.121\\EMMSDE;Initial Catalog=EMDB;User ID=jsmith;Password=s5993153492";
        using (SqlConnection con = new SqlConnection(strConnString))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.CommandText = query;
                using (SqlDataAdapter sda = new SqlDataAdapter())
                {
                    cmd.Connection = con;
                    sda.SelectCommand = cmd;
                    using (DataSet ds = new DataSet())
                    {
                        DataTable dt = new DataTable();
                        sda.Fill(dt);
                        return dt;

                    }
                }
            }
        }
    }
    protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string from = gvCustomers.DataKeys[e.Row.RowIndex].Value.ToString();
            
            GridView gvOrders = e.Row.FindControl("gvOrders") as GridView;
            gvOrders.DataSource = GetData(string.Format("select  * from outlookreport.dbo.comlog where xrefid='{0}' ", from));
            gvOrders.DataBind();
            
            string phonenumber = e.Row.Cells[1].Text.ToString();
            int celllength = phonenumber.Length;
            string sender1 = e.Row.Cells[0].Text.ToString();
            int sendercount = sender1.Length;

            e.Row.Cells[1].Width = celllength + 2;
            e.Row.Cells[0].Width = sendercount + 10;
            gvOrders.Width = 420;
            
            
            //int cellwidth = Convert.ToInt32(e.Row.Cells[0].Width);
            //int emailwidth = Convert.ToInt32(e.Row.Cells[1].Width);
            //int hyperlinkwidth = Convert.ToInt32(e.Row.Cells[2].Width);
            //gvOrders.Width = cellwidth + emailwidth + hyperlinkwidth;

        }
    }

Communication HIstory
Where it shows multiple links for "Click to view Secure Message" I want it to only display the one record that relates to the parent drop down.

So "Bob Thompson" would only have 1 drop down because it would match the Sender and the Received date on it from the query.

please change your query to:

gvOrders.DataSource = GetData(string.Format("select  * from outlookreport.dbo.comlog where xrefid='{0}' and sender='{1}' and received='{2}' ", from, sender, received));

I had to make some adjustments becuase the date would not convert so I added an ID number in the SQL

Code is like this protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string from = gvCustomers.DataKeys[e.Row.RowIndex].Values[0].ToString();
            string sender25 = gvCustomers.DataKeys[e.Row.RowIndex].Values[2].ToString();
            string recieved = gvCustomers.DataKeys[e.Row.RowIndex].Values[1].ToString();
            //DateTime recieveddate = gvCustomers.DataKeys[e.Row.RowIndex].Values[1];
            GridView gvOrders = e.Row.FindControl("gvOrders") as GridView;
            gvOrders.DataSource = GetData(string.Format("select  * from outlookreport.dbo.comlog where xrefid='{0}' and sender='{1}' and id='{2}'", from, sender25,recieved));
            //gvOrders.DataSource = GetData(string.Format("select  * from outlookreport.dbo.comlog where xrefid='{0}' and daterec='{1}' ", from));
            gvOrders.DataBind();
         
            string phonenumber = e.Row.Cells[1].Text.ToString();
            int celllength = phonenumber.Length;
            string sender1 = e.Row.Cells[0].Text.ToString();
            int sendercount = sender1.Length;

            e.Row.Cells[1].Width = celllength + 2;
            e.Row.Cells[0].Width = sendercount + 10;
            gvOrders.Width = 420;
           
           
            //int cellwidth = Convert.ToInt32(e.Row.Cells[0].Width);
            //int emailwidth = Convert.ToInt32(e.Row.Cells[1].Width);
            //int hyperlinkwidth = Convert.ToInt32(e.Row.Cells[2].Width);
