400 Components Dictionary

Example

The following example creates a range of items in the DataSet component and modifies the

gradeLevel property of each item. To test this example, drag a DataSet component to the

Stage, and give it an instance name of

my_ds. With the DataSet component selected, create

three new properties in the schema of the DataSet component by using the Schema tab in the

Component inspector. Name the new properties

name, id, and gradeLevel, and give them

the data types of String, Number, and Number respectively. Add a copy of the

DataBindingClasses compiled clip from the Classes common library (Window > Common

Libraries > Classes) and add the following ActionScript to Frame 1 of the main timeline:

my_ds.addItem({name:"Billy", id:104, gradeLevel:4});

my_ds.addItem({name:"Bobby", id:105, gradeLevel:4});

my_ds.addItem({name:"Carrie", id:106, gradeLevel:4});

my_ds.addItem({name:"Cathy", id:110, gradeLevel:4});

my_ds.addItem({name:"Mally", id:112, gradeLevel:3});

my_ds.addSort("name_id", ["name", "id"]);

my_ds.setRange(["Bobby", 105], ["Cathy", 110]);

while (my_ds.hasNext()) {

my_ds.gradeLevel = "5"; // Change all of the grades in this range.

my_ds.next();

}

my_ds.removeRange();

my_ds.removeSort("name_id");

for (var i=0; i<my_ds.length; i++) {

trace(my_ds.items[i].name + " > " + my_ds.items[i].gradeLevel);

}
