The following code creates a new sort named that performs a descending, case-
"nameSort"
insensitive sort on the DataSet object's field.
"name"
import mx.data.components.datasetclasses.DataSetIterator;
my_ds.addItem({name:"Milton", years:3});
my_ds.addItem({name:"mark", years:3});
my_ds.addItem({name:"Sarah", years:1});
my_ds.addItem({name:"michael", years:2});
my_ds.addItem({name:"Frank", years:2});
my_ds.addSort("nameSort", ["name"], DataSetIterator.Descending |
DataSetIterator.Unique | DataSetIterator.CaseInsensitive);
In the following example, you can dynamically add data to a DataSet component by entering
first and last names into TextInput component instances on the Stage and clicking the Submit
button. After you add items to the DataSet component, you can clear the data set by clicking
the Clear button on the Stage. Drag a DataGrid component to the Stage, and give it an
instance name of Drag two Button components to the Stage, and give them instance

the Component inspector. Finally, paste the following code in the first frame of the
main timeline:
import mx.controls.Alert;
my_ds.addSort("lastFirst", ["lastName", "firstName"]);
my_dg.enabled = false;
clear_button.enabled = false;
submit_button.label = "Submit";
clear_button.label = "Clear";
my_ds.addEventListener("addItem", addItemListener);
my_ds.addEventListener("modelChanged", modelChangedListener);
submit_button.addEventListener("click", submitListener);
clear_button.addEventListener("click", clearListener);
