endrow	The last row in the range of rows for which you want to set the height

Usage

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.

Examples

Example 1

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

dw_1.SetDetailHeight(2, 3, 500)

Example 2

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.SetTransObject(SQLCA)

dwc.Retrieve( )

dwc.SetDetailHeight(2, 3, 0)
