            stripeRows: true,
            width: 550,
            loadMask: true,
            columnLines: true,
            id: 'productsGrid',
               ...
    and i load data from my server in the grid.

    Code:
    jsonStoreProducts.load();

    In the store's load event, do store.getTotalCount().
    This will give you the number of records loaded.
    If it is 0, show the alert .

    You mean in 1 operation you want to load records and get a message from the server side?
    That is not possible but you can do this.
    1. Load data
    2. In the load event, do a Ext.Ajax.request that will get the message from the server
    3. On success event , show the alert with the message

    I your server side code, you could always check if you're returning zero records, and if so - return an additional message in the response to be used in your pop up message.

    This way, you only need one request.
