You can use Linq to filter rows 

var results = from myRow in dt_Main.AsEnumerable()
              where myRow.Field<TimeSpan>("timeOnlyStart") < TimeSpan.Parse("10:00:00")
              select myRow;
gridControl3.DataSource  = results.AsDataView();

if you need datatable 

 var resultsdt = results.CopyToDataTable()
