Hi,
Below code will get the data from access database and show it to the grid. Please modify the mdb path and file name and also modify the select query.

C#

private void button1_Click(object sender, EventArgs e)
       {
           System.Data.OleDb.OleDbConnection conn = new   System.Data.OleDb.OleDbConnection();
           // TODO: Modify the connection string and include any
           // additional required properties for your database.
           conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
               @"Data source= C:\myAccessFile.mdb";
           try
           {
               conn.Open();
               // Insert code to process data.

               string sqlQuery = "select * from table";
               OleDbDataAdapter da = new OleDbDataAdapter(sqlQuery, conn);

               DataTable dtTable = new DataTable();

               da.Fill(dtTable);

               dataGridView1.DataSource = dtTable;
           }
           catch (Exception ex)
           {
               MessageBox.Show("Failed to connect to data source");
           }
           finally
           {
               conn.Close();
           }
       }

Best Regards,
Muthuraja
