c# - Need help taking the results of a SQL select statment and outting them into a gridview -

- 

try         {             sqlcommand cmd = new sqlcommand(select [name], count([name]) count [delegationtracker] [date] = @date group [name], connection);conn);              sqlcommand cmd = new sqlcommand(select @user_tested whmis_user_tests;, connct);             cmd.parameters.clear();             cmd.parameters.add(@name, sqldbtype.varchar).value = httpcontext.current.session[name].tostring();             cmd.parameters.add(@date, sqldbtype.varchar).value = date;mmddyyyy              cmd.parameters.add(@grade, sqldbtype.varchar).value = null;             connection.open();              using (sqldatareader reader = cmd.executereader())             {                 while (reader.read())                 {                     test = reader.getvalue(0).tostring();                     test2 = reader.getvalue(1).tostring();                 }              }              sqldatareader dr = cmd.executereader();             sqldataadapter adapter = new sqldataadapter(cmd);             datatable dt = new datatable();             dt.load(dr);             adapter.fill(dt);              dataset ds = new dataset();             adapter.fill(ds);             maingridview.datasource = dt;             maingridview.datasource = ds;             maingridview.databind();             connection.close();             return true; }

the gridview not display im assuming because has no data , datatable returns 1 record in sql table not display (within gridview) dataset far can tell returns nothing

the reason have many adapters , dataset , datatable testing see worked none have produced results...

i'm not sure whats going on in sample code. looks took 2 different methods , shuffled them together. here's simple method or loading datagrid using 1 of 2 sql queries provided.

private void loaddatagrid(datagrid datagrid, datetime date, string connectionstring)  {     using (var conn = new sqlconnection(connectionstring))      {         using (sqlcommand cmd = conn.createcommand())          {             cmd.parameters.add(new sqlparameter {                 parametername = "@date",                 sqldbtype = sqldbtype.datetime,                 value = date             });             cmd.commandtext = "select [name], " +                               "       count([name]) count " +                               "from   [delegationtracker] " +                               "where  [date] = @date " +                               "group  [name]";              conn.open();             try              {                 using (sqldatareader reader = cmd.executereader())                  {                     datagrid.datasource = reader;                     datagrid.databind();                 }             }                          {                 conn.close();             }         }     } }
