How do I only bind certain columns with a DataGrid?

I have the following code that binds a datatable to my datasource. Problem 
is, the table has about 25 columns and I only really want to see 5 of
those 
columns. I know I can do it by changing my initial SQL query but that
means 
if I want to use other data later on I have to make another connection to 
SQL and get the additional data.

Is there a way to only bind to certain columns in my table? It is a 
webcontrol datagrid.

AllResultsDataGrid.DataSource = mySqlConnection.datasetHardware;
AllResultsDataGrid.DataMember = mySqlConnection.hardwareTableName;
AllResultsDataGrid.DataBind();

Thanks,

Grant
