send message from server

[Stephan123]

Hello !

I have a grid.

 gridProducts = new Ext.grid.GridPanel({
        store: jsonStoreProducts,
        autoHeight: true,
        stripeRows: true,
        width: 550,
        loadMask: true,
        columnLines: true,
        id: 'productsGrid',
           ...

and i load data from my server in the grid.

jsonStoreProducts.load();

In same situation i have no data and
i will send a message to the user.

Ext.messageBox.alert('no data');

I there a simple way to send a message ?

Sorry for my bad english.

Your sincerly Stephan

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 .

Hello!

Thanks for the answer. I want to publish a message,
that is created on the server. The show with the message to

Ext.messageBox.alert (myServerMessage) done.

Can I store.load () represent a message?

Sincerely yours

Stephan

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.
