panel 'afterrender' is not working

[samotnik]

hello.
Can you please help me.
I try add Listener to panel, but it is not working
I have a panel :

var panelBody = this.getEl().child('.x-panel-body');

And I try add listener to it

panelBody.on('afterrender', function() {
alert(1);}
, this);

But nothing happens

And this

Ext.EventManager.on(panelBody, 'afterrender', function() {
            alert('afterrender ! ');
        });

is not working, too

If you add the listener after it has rendered, the event won't get fired again.

mr. Animal, thank you !

[samotnik]

ok, then, I have another question
How can I know, when All content was add to the panel ?
'afterrender' alert before loaded all content in the panel

[Animal]

You might be thinking of the afterlayout event.

You will need to use {single: true} to only catch the first layout event.

[samotnik]

no, but in any case, thank you, mr. Animal !
It seems, that I have to use defer() function, I know, that it's bad solution. But I really do not uderstand, how can I catch event, when all content will innerHTML to the panel, with all css ...

[Animal]

Oh, you are not using the Panel as a Container then, but dumping some dead HTML into it?

You don't need events then. Just perform postprocessing after you've dumped the HTML in.

thank you, mr.Animal !!
How do you think, is it possible or not ?
I have a panel. panel, and I do innerHTML to it

panel.update(some_html);

and then (on the next line) I try to get offsetTop of one element from that panel. But calculate is wrong. But, if I use defer() function or just alret('bla bla bla') - calculate is right !
For example
Wrong offset:

panel.update(some_html);
alert(Ext.get('id9').dom.offsetTop); // this offset is wrong !!! It is 2100

Right offset

panel.update(some_html);
alert('this is just alert for take time of panel' rendering. When you press ok button, all contents of panel will render right');
alert(Ext.get('id9').dom.offsetTop); // this offset is right !!! It is 3200

Right offset

 (function(){
                alert(Ext.get('id9').dom.offsetTop); // this offset is right !!! It is 3200
            }).defer(500);

Why my post was not added ?

If it's a large block, and it updates asynchronously (which it seems to be) Then try using the callback option to update.
