This article describes how to click on the header of a datawindow, allows the datawindow to be ordered by that column. The name of the column header must have the same name as in the database and finish in _t
For example:
Column name: emp_id
Header name: emp_id_t
You can only sort by one column at a time.
String ls_old_sort, ls_column
Char lc_sort
/* Check when the user clicks on the header */
IF Right(dwo.Name,2) = "_t" THEN
ls_column = LEFT(dwo.Name, LEN(String(dwo.Name)) - 2)
/*Save the last sort, if there were any*/
ls_old_sort = dw_1.Describe("Datawindow.Table.sort")
/* It checks when a column was previously ordered and the one that is clicked at the moment is the same or not. If it is the same, then the order of ordering of the previous order (A - Ascending, D - Descending) is checked and changed. If the columns are not the same, order them in ascending order. */
IF ls_column = LEFT(ls_old_sort, LEN(ls_old_sort) - 2) THEN
lc_sort = RIGHT(ls_old_sort, 1)
IF lc_sort = 'A' THEN
lc_sort = 'D'
ELSE
lc_sort = 'A'
END IF
dw_1.SetSort(ls_column+" "+lc_sort)
ELSE
dw_1.SetSort(ls_column+" A")
END IF
dw_1.Sort()
END IF
