    Okay, here is how I do such things...

        GridFieldDAO dao = new GridFieldDAO();
        //Load My DataTable
        DataTable dt = dao.getDT();
        //Get My rows based off selection criteria
        DataRow[] drs = dt.Select("(detailID = 1) AND (detailTypeID = 2)");
        //make a new "results" datatable via clone to keep structure
        DataTable dt2 = dt.Clone();
        //Import the Rows
        foreach (DataRow d in drs)
        {
            dt2.ImportRow(d);
        }
        //Bind to my new DataTable and it will only show rows based off selection 
        //criteria
        myGrid.DataSource = dt2;
        myGrid.DataBind();
    

    Notice in my Select() I put the criteria in Parens between AND and OR

    Hope this helps! Mike V
