query result doesn't appear in datagrid

[arian]

Hello,

I've written the following code to show a query result in a datagrid, but I get an empty datagrid after the code is run!
Could you please tell me how I can fix the problem?
Do I need to assign the values to each row in the datagrind row by row using a loop?

OleDbConnection DBConnection = new System.Data.OleDb.OleDbConnection();
            
            DBConnection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Chakaveh\Desktop\datagridTest\test1\dgt.accdb";

            string SQL = "SELECT * FROM dgtest";

            OleDbCommand cmd = new OleDbCommand(SQL,DBConnection);

            OleDbDataAdapter da = new OleDbDataAdapter(cmd);

            DataSet ds = new DataSet();

            da.Fill(ds);

            DataTable entries = ds.Tables[0];

            dataGridView1.ReadOnly = true; 

            dataGridView1.DataSource = entries;

            cmd.Dispose();

            DBConnection.Close();

thank you

I had made a mistake adding 2 columns to the datagrid at the beginning
The result was shown after the columns and I wasn't paying attention to the scrol
The code is perfectly running
