    //右键菜单代码关键部分
    DMS.Desktop.Grid.addListener('rowcontextmenu', function rightClickFn(DMS.Desktop.Grid, rowIndex, e){

      });

   
    DMS.Desktop.Grid.superclass.constructor.call(this, {

        height: 350,
        sm: new Ext.grid.RowSelectionModel({
            singleSelect: true
        })
    });
};
  
Ext.extend(DMS.Desktop.Grid, Ext.grid.GridPanel, {

});


看了一些资料，想价格右键菜单。其他的因该都没有问题  就是这个
    //右键菜单代码关键部分
    DMS.Desktop.Grid.addListener('rowcontextmenu', function rightClickFn(DMS.Desktop.Grid, rowIndex, e){ 
        e.preventDefault();
        rightClick.showAt(e.getXY());
      });
加上后就显示不出来， 什么问题呀，大家帮下忙。

已解决，嘿嘿
