javascript - In ExtJS, how to add a custom CSS class to data grid rows?

Question

How do I add custom CSS classes to rows in a data grid (Ext.grid.Panel)?

I'm using ExtJS 4.0.

Answer 1

The way to do it is to define viewConfig on the grid:

Ext.create('Ext.grid.Panel', {
    ...

    viewConfig: {
        getRowClass: function(record, index, rowParams, store) {
            return record.get('someattr') === 'somevalue') ? 'someclass' : '';
        }
    },

    ...
});
