Hello,

C#

MySqlConnection conn = new MySqlConnection("SERVER=....");
MySqlDataAdapter ad;
DataSet ds = new DataSet();

ds.Tables.Add("111");
ds.Tables.Add("222");

ad = new MySqlDataAdapter("SELECT * FROM 111", conn);
ad.Fill(ds.Tables["111"]);
datagridview1.DataSource = ds.Tables["111"];

ad = new MySqlDataAdapter("SELECT * FROM 222", conn);
ad.Fill(ds.Tables["222"]);
datagridview2.DataSource = ds.Tables["222"];

'datagridview2' shows table["111"] instead of table["222"].
What am I missing or doing wrong?

What I have tried:

It works with

C#

DataTable dt1, dt2;
MySqlDataAdapter ad1, ad2;

But I don't understand

datagridview2.DataSource = ds.Tables["222"];

shows Table["111"].

Thank you in advance.

Use below code. The reason is when we add using

ds.Tables.Add("111");

it is not able to add table ot ds at 0 and 1 index.

DataTable dt1 = new DataTable();
DataTable dt2 = new DataTable();
MySqlConnection conn = new MySqlConnection("SERVER=....");
MySqlDataAdapter ad;
DataSet ds = new DataSet();

ad = new MySqlDataAdapter("SELECT * FROM 111", conn);
ad.Fill(dt1);


ad = new MySqlDataAdapter("SELECT * FROM 222", conn);
ad.Fill(dt2);

ds.Tables.Add(dt1);
ds.Tables.Add(dt2);

datagridview1.DataSource = ds.Tables[0];
datagridview2.DataSource = ds.Tables[1];
