Call SetDetailHeight in a script to vary the amount of space assigned to rows in a DataWindow control or DataStore. You cannot specifically set the height for different rows when you define a DataWindow object in the DataWindow painter, although you can turn on the Autosize Height property for the detail band so that the height of each row is determined by the data.

You can set the detail height of one or more rows to zero, which hides them from view.


This statement sets the height of rows 2 and 3 to 500:

dw_1.SetDetailHeight(2, 3, 500)

This script retrieves rows for a DropDownDataWindow associated with the Company_Name column. It then hides rows 2 and 3 of the DropDownDataWindow by setting their detail height to 0:

DataWindowChild dwc;
integer rtncode;
rtncode = dw_1.GetChild("company_name", dwc)
IF rtncode < 0 THEN HALT
dwc.Retrieve( )
dwc.SetDetailHeight(2, 3, 0)
