I need to load a win forms chart with data from my sql db
and i want to use this type of structure(I'm still new with charts)
This is the method I use when populating controls mostly...
The stored proc is not a problem, only the code behind

Can anyone please help me with this code?

clsConnection conn = new clsConnection();

                using (SqlCommand sqlcomm = new SqlCommand())
                    SqlDataReader sqlread;

                    sqlcomm.Connection = conn.connection;
                    sqlcomm.CommandType = CommandType.StoredProcedure;
                    sqlcomm.CommandText = "usp_LoadChart";
                    sqlcomm.Parameters.Add("@ParameterExample", SqlDbType.NVarChar, 50).Value = cboExample.Text.ToString().Trim();

                    sqlread = sqlcomm.ExecuteReader();

                    while (sqlread.Read())

What is wrong with it ? This code reads data, it does not interact with a chart. What is the issue ? What charts are you using ?

You need to read the MSDN online help for charts. You need to setup the datasource, databind it, setup your series, your axis, labels, and data points.
