关于 extjs grid一些常见问题

1.自动调整列宽

viewConfig: {forceFit:true},

根据莫一列值改变行背景色   
viewConfig: {
                columnsText: "显示/隐藏列",
                sortAscText: "正序排列",
                sortDescText: "倒序排列",

                forceFit: true
               getRowClass: function (record, rowIndex, rowParams, store) {
                    if (record.data.state == -1)
                   
                   return 'my_row_Red';

                 

                   return;
               }

            }

双击grid1从新加载grid2 store
1.首先给grid注册一个双击事件
 this.grid1.on('rowdblclick', this.rowdblclickFn, this); //添加行双击事件

 2.rowdblclickFn: function (grid, rowindex, e) {//行双击事件

        var _gd2_store = this.grid2.getStore();

        grid.getSelectionModel().each(function (rec) {
            //alert(_grid2.id);
            //alert(_gd2_store.getCount());
            _pid = rec.get("sid");

            _gd2_store.load({ params: { start: 0, limit: _pageSize1, pid: _pid} });
        });

    }
