c# - Populate a datagridview with sql query results

Question

I'm trying to present query results, but I keep getting a blank data grid. It's like the data itself is not visible

Here is my code:

 private void Employee_Report_Load(object sender, EventArgs e)
 {
     string select = "SELECT * FROM tblEmployee";
     Connection c = new Connection();
     SqlDataAdapter dataAdapter = new SqlDataAdapter(select, c.con); //c.con is the connection string
     SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter);

     DataTable table = new DataTable();
     table.Locale = System.Globalization.CultureInfo.InvariantCulture;
     dataAdapter.Fill(table);
     bindingSource1.DataSource = table;

     dataGridView1.ReadOnly = true;        
     dataGridView1.DataSource = bindingSource1;
}

What's wrong with this code?

Answer 1

Here's your code fixed up. Next forget bindingsource

 var select = "SELECT * FROM tblEmployee";
 var c = new SqlConnection(yourConnectionString); // Your Connection String here
 var dataAdapter = new SqlDataAdapter(select, c); 

 var commandBuilder = new SqlCommandBuilder(dataAdapter);
 var ds = new DataSet();
 dataAdapter.Fill(ds);
 dataGridView1.ReadOnly = true; 
 dataGridView1.DataSource = ds.Tables[0];
