datagridview columns inquiry

[popskie]

hi,
im new to vs2005. Is this posible to resize the columns and im using c#? 2nd question is how to make a eventhandler of my button inside the columns?

dataset ds = new dataset();					            
MySqlDataAdapter myadapter =	new MySqlDataAdapter();
myadapter.SelectCommand = new MySqlCommand();
myadapter.SelectCommand.Connection  = stsqcon.getConnection();
myadapter.SelectCommand.CommandText = " Select * from ....";
myadapter.SelectCommand.Parameters.Add("?veh_code",MySqlDbType.Int32 ,4);
myadapter.SelectCommand.Parameters["?veh_code"].Value = lv1.SelectedItems[0].SubItems[1].Text;
myadapter.Fill(ds,"element1");
datagridview1.DataSource = ds;
datagridview1.DataMember = "element1";

Thanks,
Popskie
