UIComponent class: oracle.adf.view.faces.bi.component.pivotTable.UIHeaderCell
Component type: oracle.dss.adf.pivotTable.HeaderCell
Each immediate child of a Pivot Table component must either be a
<dvt:dataCell> component. The Pivot Table should contain at most one headerCell component and at most one dataCell component. These components make it possible to customize the cell content via stamping. The header cell can contain one or more read-only components. This tag also supports customized CSS style for the cells.
Rather than having a separate child component for each header cell in the pivot table, the child component of the headerCell component is repeatedly rendered (stamped) once per header cell. Because of this stamping behavior, only certain types of components are supported as children inside a Header Cell.
As the headerCell content is stamped, the data for the current header cell is copied into an EL reachable property. The name of this property is defined by the var property on the Pivot Table. Once the Pivot Table has completed rendering, this property is removed (or reverted back to its previous value).
Examples of components that are supported by
<dvt:headerCell> include but are not limited to the following:
The headerCell should have only one child component. If multiple children are desired, they should be wrapped in another component. If no layout is desired, <af:group> can be used, which simply renders its children without adding layout, and is consequently lightweight. If layout is desired, a layout component like <af:panelGroupLayout> can be used instead. If multiple children are present without being wrapped, the current behavior is to vertically stack the components, but no guarantees or support are provided for this usage. To achieve vertical stacking, consider <panelGroupLayout layout="vertical">.
Apply Request Values
|Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.|
|attributeChangeListener||javax.el.MethodExpression||Only EL||a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.|
|binding||oracle.adf.view.faces.bi.component.pivotTable.UIHeaderCell||Only EL||an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.|
|id||String||No||the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
|rendered||boolean||Yes||whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.|
