Data Iterator

The iterator component iterates over rows of model data allowing values from each row to be used in child components. For each row of data available a set of child components will be rendered, the iterator tag itself does not have any control over what is rendered, it just provides data to child components.

 

Properties and All Attributes views

The Properties view for a component shows the most common set of attributes you can set on a component, and, depending on the component, you might also see options for adding controls, actions, or other components. To open the Properties view, click

Window | Show View | Properties.

These common attributes for the Data Iterator component display on the hx:dataIterator and Styles tabs in the Properties view. See the Data Iterator attributes table for a list of attributes.

The All Attributes view shows a table of all the attributes you can set on a component, which includes those attributes you can access from the Properties view. To switch to the All Attributes view, click the

All Attributes icon in the upper right corner of the Properties view.
