You can do something like this.

To display only particluar columns in a DataGridView first you take the data in a DataTable like this.

String query="Your query to dispplay columns from the database";
SqlCommand cmd=new SqlCommand(query,con); //con is your Connection String
con.Open();
DataTable dt=new DataTable();
SqlDataAdapter da=new SqlDataAdapter(cmd);
da.Fill(dt); //Now this DataTable is having all the columns lets say
/* Now take another temporary DataTable to display only particular columns*/
DataTable tempDT=new DataTable();
tempDT=dt.DefaultView.ToTable(true,"Your column name","your column name");
//Now bind this to DataGridView
grid.DataSource=tempDT;
con.Close();

I know this is a quite long process.Those who go for the performance might not like this. :P

But i think it works fine.
