Grid methods not found?

[ferr]

I'm reading through the YAHOO.ext.grid.Grid manual and can only get some of the functions to work. Functions such as grid.getSelectedRowId return this error in Firebug:
grid.getSelectedRowId is not a function

What is the deal? I am trying to make a few function calls such as that in the grid.on celldblclick event handler.


grid.on('celldblclick', function(grid, rowIndex, columnIndex, e)
{
var selectedRow = ds.getAt(rowIndex).id;
var selectedCol = ds.getAt(columnIndex).id;

//Ext.MessageBox.alert('Double Clicked', 'Row: ' + rowIndex + ', Col: ' + columnIndex);

var itemId = grid.getSelectedRowId();
alert(itemId);

if(columnIndex == 0)
{
}

});

Ah, turns out to be simple. I'm using the EditorGrid which has half as many methods as Grid. 8-|
