It can be very useful to associate a collection with a UI components, and Data Binding Manager will convert the collection into UI components accordingly.
- Prepare the data source of Collection
- Associate the collection with model attribute of those supported UI components, ex. Listbox, Grid, and Tree.
- Define a template of UI component
- Define a variable, whatever you want, to represent each instance in the Collection with self attribute.<component-name self="@{each='variable-name'}"/> The variable-name could only be seen by component-name and its child components.
- Associate UI components with the variable
<component-name attribute-name="@{variable-name.attribute-name}"/>
In the following example, we demonstrate how to associate a collection with Listbox to display a list of persons.
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>
<window width="500px">
<zscript><![CDATA[
//prepare the example persons List
int count = 30;
List persons = new ArrayList();
for(int j= 0; j < count; ++j) {
Person personx = new Person();
personx.setFirstName("Tom"+j);
personx.setLastName("Hanks"+j);
persons.add(personx);
}
]]>
</zscript>
<listbox rows="4" model="@{persons}">
<listhead>
<listheader label="First Name" width="100px" />
<listheader label="Last Name" width="100px" />
<listheader label="Full Name" width="100px" />
</listhead>
<!-- define variable person here-->
<listitem self="@{each='person'}">
<listcell>
<textbox value="@{person.firstName}" />
</listcell>
<listcell>
<textbox value="@{person.lastName}" />
</listcell>
<listcell label="@{person.fullName}" />
</listitem>
</listbox>
</window>
