Class \Prado\Web\UI\WebControls\TContentPlaceHolder
TContentPlaceHolder reserves a place on a template where a TContent control can inject itself and its children in. TContentPlaceHolder and TContent together implement a decoration pattern for prado templated controls. A template control (called content control) can specify a master control whose template contains some TContentPlaceHolder controls. TContent controls on the content control's template will replace the corresponding TContentPlaceHolder controls on the master control's template. This is called content injection. It is done by matching the IDs of TContent and TContentPlaceHolder controls.

This method is invoked after the control is instantiated on a template.
This overrides the parent implementation by registering the content placeholder control to the template owner control. The placeholder control will NOT be added to the potential parent control! |
