Class: cWebListExpandPanel

---------------cWebListExpandPanel

This control should be used in combination with a cWebList, the object should be a direct child of the cWebList object. The panel is a container that can contain any other control and it will expand below a specific row. Only one row can be expanded, so when expanding below another row all other rows will collapse. By default, the panel will size to its content, but a fixed height can also be set using piHeight.

When the panel expands (and collapses) is configured by the peMode property. It can open automatically when the current row is changed, only when a row is clicked or manually (from DataFlex code).

Drag and Drop Support

This control can be used as a valid drop target by registering it as such in a cWebDragDropHelper object.

The supported actions for this control are:
- C_WebDropOnControl

This allows the control to accept data dragged from elsewhere in the control (if configured that way) and can also be used to accept files when registered within a cWebDragDropFileHelper.
