DataSet.filterFunc 363

The following example populates a DataGrid component from content dynamically loaded

using the XMLConnector component. When a user clicks a CheckBox instance on the Stage,

the contents of the DataSet component are filtered and are updated automatically in the

DataGrid component.

Drag the following components to the Stage, and give them the following instance names:

■ CheckBox (editorsChoice_ch)

■ DataGrid (reviews_dg)

■ DataSet (reviews_ds)

■ XMLConnector (reviews_xmlconn)

Download a copy of the following XML document, and save it to your local hard disk:

www.helpexamples.com/flash/xml/reviews.xml. This XML document loads dynamically

using the XMLConnector component,. You’ll use the local copy to import the XML schema

into the DataSet component. Select the XMLConnector instance on the Stage, and select the

Schema tab from the Component inspector. Select the

results property, and click Import a

Schema From a Sample XML File. Select the XML document that you downloaded to your

local hard disk, and click Open. The schema of the XML document should import into the

DataSet component. With the

reviews_xmlconn XMLConnector instance still selected on

the Stage, add a binding from the

reviews_xmlconn.results.reviews.review array to the

dataProvider property of the reviews_ds DataSet instance. Set the direction of the data

binding to Out in the Bindings tab. Select the

reviews_ds DataSet instance on the Stage,

and add another binding for the

dataProvider property. With the reviews_ds instance

selected, select the Bindings tab of the Component inspector. Click the Add Binding button

and add a binding from the

dataProvider property of the DataSet component to the

dataProvider property of the reviews_dg DataGrid instance.
