C# - Datagridview inyect a MySql DataSource

Datagridview 

To inyect a DataSource to a Datgridview to update it automatically


  • Create your query to fetch the data
            query = "SELECT id, signum as Signum, name as Name, 
                 remote_IP as 'Remote IP', remote_port as 'Remote Port' " +
                "FROM eterminal.rel_user_session where signum = '" + signum + "'";


  • Create a MySqlDataAdapter, this object will update your datagridview
    • The Second parameter is an active connection of type MySqlConnection

MySqlConnection mconnection = new MySqlConnection("Server=146.250.116.2; Database=MydB; Uid=User; Pwd=pwd2@");         
MySqlDataAdapter adapter = new MySqlDataAdapter(query,  connection.getActiveConnection());



  • This help to create the proper commands to update, delete, add
            MySqlCommandBuilder cb = new MySqlCommandBuilder(adapter);

  • The DataSet is where the information is allocated and is used to fill the datagridview
    • The adapater will perform all the changes
            ds = new DataSet();
            adapter.Fill(ds, "session");


  • Assign the DataSet to fill the datagridview
            datagridview.DataSource =  ds.Tables[0];


  • The last step is update the datageridview, in the event you want. Ex in a click button to save the chage you need to add
    • you are indicating to the adapter that need to update all the changes
            adapter.Update(ds, "session");
