Trying to bind the data that I recover from ADO query, I am getting the same error after trying different approach (usaing dataTable, DataView,...). The last one I used is the next:
string query = "SELECT * FROM productos";
MySqlConnection con = new MySqlConnection(connectionString);
MySqlCommand cmd = new MySqlCommand("select * from productos");
con.Open();
cmd.Connection = con;
MySqlDataReader dr = cmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dr);
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
Another approach I used was:
MySqlConnection Com = new MySqlConnection(connectionString);
MySqlCommand cmd = new MySqlCommand(query);
Com.Open();
cmd.Connection = Com;
Datos = cmd.ExecuteReader();
dt.Load(Datos);
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
The error returned in all cases is:
System.InvalidOperationException: 'Cannot determine table from data source. Use the MetaTable.MapTable method to establish an association between a data source and a MetaTable instance.'
