How to scroll selected record into view

[tvanzoelen]

I have this code to select a record and scroll it into view, but it is not working.

 grid.getSelectionModel().select(record);
 grid.getView().focusRow(record);

If somebody knows how to do this, plz tell me!

focusRow doesn't do it? What version?

Using the Array grid example, I did the following and it worked for me:

        var rec  = store.getAt(15),
            view = grid.getView();

        view.focusRow(rec);

it scrolled down until 'Intel Corporation' was in view.

I see, it works if the items are loaded in the view, but how to know that moment in a case like this?

Ext.onReady(function() {
    Ext.QuickTips.init();

    // setup the state provider, all state information will be saved to a cookie
    Ext.state.Manager.setProvider(Ext.create('Ext.state.CookieProvider'));

    // sample static data for the store
    var myData = [

                        alert((rec.get('change') < 0 ? "Hold " : "Buy ") + rec.get('company'));
                    }
}]
                }
        ],
        height: 350,
        width: 600,
        title: 'Array Grid',
        viewConfig: {
            stripeRows: true
        }
    });

    var win = Ext.create('Ext.window.Window', {
        items: [grid]
    });

    win.on('show', function() {
        var rec = store.getAt(15);
        var view = grid.getView();

        view.focusRow(rec);
    });

    win.show();

});

This is the example, but in my code I do it on the callback if I load the store. At that moment the records are visible in the grid/view but the scrollers are not ready. then the focusRow will not work.
