List (PRIM_MD.List)

Simple list control with inplace designable list entry

Ancestors - Container (PRIM_CPST) Control (PRIM_CTRL) Object (PRIM_OBJT)

Details

PRIM_MD.List is a simple material list control that has inplace designable items.
 
Each instance is presented as an item in a typical tree structure. It is the developer's responsibility to show indentation and expand/collapse information. However, when items are expanded or collapsed, the list will manage the items and show or hide the appropriate ones.
 
The inline designer allows for dragging and dropping controls into the list.
 
Supported column types - Edit, SpinEdit,  DateTime, Flat Button, Raised Button, Switch and CheckBox.
This example shows a simple list with a number and button. The button is hidden if the row is an even numbered row. Clicking the button will delete the row.
