PHP Class Prado\Web\UI\JuiControls\TJuiEventParameter

TJuiEventParameter encapsulate the parameters for callback events of TJui* components. Any parameter representing a control is identified by its clientside ID. TJuiEventParameter contains a {@link getControl} helper method that retrieves an existing PRADO control on che current page from its clientside ID as returned by the callback. For example, if the parameter contains a "draggable" item (as returned in {@link TJuiDroppable}::OnDrop event), the relative PRADO control can be retrieved using:


$draggable = $param->getControl($param->getCallbackParameter()->draggable);

A shortcut __get() method is implemented, too:


$draggable = $param->DraggableControl;
