How can I change the row colour in datagrid based on severity?

Question

How can I change the row colour in datagrid based upon the severity condition? I'm new to this EXTJS topic. I used to reader to read, store to store and writer to write the data. After fetching all the data into the grid, how can i change the row colour in datagrid based upon the severity condition? Can you explain me too bit with code working?

Answer 1

you can use the GridView class (Ext.grid.GridView) to manipulate the user interface of the grid. You can also the viewConfig property of the GridPanel. Here is an example:

viewConfig: {
        //Return CSS class to apply to rows depending upon data values
        getRowClass: function(record, index) {
            var c = record.get('change');
            if (c < 0) {
                return 'price-fall';
            } else if (c > 0) {
                return 'price-rise';
            }
        }
    }

ps: Example taken from ExtJS API documentations itself

The price-fall and price-rise are CSS that have background colors set accordingly. eg:

.price-fall { 
 background-color: #color;
}

.price-rise {
 background-color: #color;
}
