I have a csv file and I import it to datagridview. Now I filter it using 2 datetimepickers. One for start and other for end.
When click it must loop through the column names and must display only the columns which matches start date, range of columns between start and end date,enddate. please see the image attached.
First image shows the datagridview when loaded from csv.
second shows the desired output when filtered using datetimepickers.
