any idea how to manage this issue?

Answer 1

you have to use itemTpl property of the Ext.dataview.DataView class, see config: itemTpl Basically this is an expression of Ext.XTemplate

In your case imagine you defined in model field unread , then you can write something like:

 config: {
        itemTpl: [
            '<div',
            '<tpl if="unread"> class="my-unread-css"</tpl>',
            '>',
            '{newsText}',
            '<div>',
        ]
 }

Then somewhere in controller call of the function will remove css class from the list item.

 function markAsRead(newsModel) {
      newsModel.set('unread', false);
 }
