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?

xtype: 'actioncolumn',
width: 50,
items: [{
icon: '../shared/icons/fam/delete.gif', // Use a URL in the icon config
tooltip: 'Sell stock',
handler: function(grid, rowIndex, colIndex) {
var rec = store.getAt(rowIndex);
alert("Sell " + rec.get('company'));
}
}, {
getClass: function(v, meta, rec) { // Or return a class from a function
if (rec.get('change') < 0) {
this.items[1].tooltip = 'Hold stock';
return 'alert-col';
} else {
this.items[1].tooltip = 'Buy stock';
return 'buy-col';
}
},
handler: function(grid, rowIndex, colIndex) {
var rec = store.getAt(rowIndex);
alert((rec.get('change') < 0 ? "Hold " : "Buy ") + rec.get('company'));
}

}
],

title: 'Array Grid',
viewConfig: {

}
});

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.
