i want to ask, how do i set condition or expression where the column table is type of timespan
.
when i use this code
private void button1_Click(object sender, EventArgs e)
{
string expression2;
expression2 = "timeOnlyStart < '" + TimeSpan.Parse("10:00:00") + "'";
DataTable yyy = dt_Main.Select(expression2).CopyToDataTable();
gridControl3.DataSource = yyy;
}
EDITED : timeOnlyStart is a column start

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()
