    Try something like the following:

    Code:
    var examplegrid = {    
        id:'examplegrid',
        xtype:'grid',
        store: store,
        columns: columns,
        listeners: {
            viewready: function(thisGrid) {
                thisGrid.getSelectionModel().selectFirstRow();
            }
        }
    };

    You cannot run EXT functions on normal DOM elements, you have to either reference them by their defined variable names, or via:
    Code:
    var grid = Ext.getCmp('ID_of_the_EXT_object');
    Only once you have an EXT object as the variable can you then run EXT functions against them.
