Reports and Queries

List Box control based on a data file

For a List Box control based on a data file, <List Box>.Count returns:
  • the total number of records found in the linked file if no filter was defined.
  • the number of records matching the filter if a filter was defined.
  • the number of records found in the query linked to the control.
The end of initialization code of control is run once the total is calculated.

Caution: The time for calculating the number of records can be quite long

Last element

To position on the last element of List Box control, use the following syntax:
<List Box control>.SelectPlus(<List Box control>.Count)
or
<List Box control> = <List Box control>.Count
or
<List Box control> = <List Box control>.Count()

Miscellaneous

  • To find out the number of rows in a Table control, use <Table>.Count.
  • <List Box>.Count can be used on a "Combo Box" table column.
