DataSet.useSort() 409

Example

The following example uses DataSet.hasSort() to determine if a sort named "customer"

exists. If it does, the code calls

DataSet.useSort() to make "customer" the current sort.

Otherwise, the code creates a sort by that name using

DataSet.addSort().

if (my_ds.hasSort("customer")) {

my_ds.useSort("customer");

} else {

my_ds.addSort("customer", ["customer"], DataSetIterator.Descending);

}
