ZK List Box : How to show particular row in different color in MVVM

In this example, we will see how to change the color based on some conditions.

ZK MVVM List Box Select All and Unselect all Records

I have a list box with multiple selection allowed and paging. Actually it means I have 'select all' checkbox in list box header, which allows me select all entries that shown on the current page.

Problem statement: I did not find a way how to catch events from 'select all' checkbox. Actually, I need select all entries (on all pages and not on displayed page!)  when 'select all' checked. And deselect all entries on all pages when 'select all' unchecked.
 
Since 6.5.5, The Select all checkbox on listheader now support onCheckSelectAll event that can determine whether it is checked or not.
