Try this:

try
{
     DataTable k = new System.Data.DataTable();
    string str = "Data Source=C:\\Documents and Settings\\almas\\Desktop\\BazarKhodro\\khodro.sdf";
    Qconnection.ConnectionString = str;
    Qcommand.Connection = Qconnection;
 

    string commandText = "select name,lname,phone,mobile,address from moshtari where name=@name and lname=@lname";
    Qcommand.Parameters.AddWithValue("@name", textBox3.Text);
    Qcommand.Parameters.AddWithValue("@lname", textBox4.Text);
    Qcommand.CommandText = commandText;
    Qcommand.CommandType = CommandType.Text;
    SqlCeDataAdapter a = new SqlCeDataAdapter();
 
     a.SelectCommand = Qcommand;
 

      a.Fill(k);
      BindingSource bSource = new BindingSource();
 
      bSource.DataSource = k;
 
      dataGridView1.DataSource = bSource;
 
    Qconnection.Close();
 

}

If you're saying that you want to use your own names for the column headers istead of the field names defined in the database, you can do this:

...
Qconnection.Open();
Qconnection.Close();
dataGridView1.DataSource = k;
 
dataGridView1.Columns[0].Name = "My Name For Column 0";
dataGridView1.Columns[1].Name = "My Name For Column 1";

You can change the HeaderText = "Column Name" in source code also.
