how to scroll extjs 4 grid horizontally

Question

What is the proper way to scroll a grid horizontally on load.

I want to scroll to a particular grid column on load.

I can focus the column I want using this:

dataStore.on('load', function() {
     var cl = dataGrid.columns[43];
     cl.focus();
});

but the grid does not scroll when I do this.

One possibility is to use scrollByDeltaX. Example:

viewready: function(){
    var c = this.columns[5];
    var p = c.getPosition();

    this.scrollByDeltaX(p[0]);
}
