An Integer data type value that specifies the number of items that are contained in a form list control.
Remarks
The following example shows a call to the getCount method. The while select statement retrieves account numbers from the CustTable table and then stores the data in a container. The items in the variable are added to the form list control by calling the FormListControl.addItem method.

{
Args args;
Form form;
FormRun formRun;
FormBuildDesign formBuildDesign;

// Create the form header.

// Add data sources to the form.

formBuildDataSource = form.addDataSource(dictTable.name());
formBuildDataSource.table(dictTable.id());
// Create the form design.
formBuildDesign = form.addDesign("Design");
formBuildDesign.caption("myForm");
// Add a form list control.
formBuildListControl =
formBuildDesign.addControl(FormControlType::ListView,"List");

// Create the run-time form.

formRun.run();
formRun.detach();
formListControl = formRun.control(idx4);
// Add items to the form list control.
while select custTable
where custTable.AccountNum >=
"4000" && custTable.AccountNum <= "4040"
{
conAccountNum += [[custTable.AccountNum]];
}
numAccounts = conlen(conAccountNum);
for(i = 1; i <= numAccounts; i++)
{
string = conPeek(conAccountNum,i);
formListItem = new FormListItem(string);
item = formListControl.addItem(formListItem);
}
numItems = formListControl.getCount();
