单击Extjs Grid RowExpander时出现滚动问题

我在使用extjs grid rowexpander时遇到了一个问题。 复制它的步骤： 1.展开第一行。 2.现在滚动到网格的最后一条记录。 3.现在展开最后一行。您将看到滚动条自动移动到顶部

谢谢你的帮助

我已经将您的示例粘贴到Sencha小提琴中，虽然这在6.0.0到6.0.2中发生，但在6.2.0到6.5.0中似乎是固定的

因此，我将代码与不工作的源代码进行了比较，发现了变化。这里有一个适用于您的工作覆盖：

Ext.define('Override.RowExpander',{
    override:'Ext.grid.plugin.RowExpander',
    toggleRow: function(rowIdx) {
        this.callParent(arguments);
        this.grid.ensureVisible(rowIdx);
    }
});

你能提供小提琴样品吗？如果没有网格数据，它怎么能被复制？@harshitsah你可以用senchafiddle粘贴上面的代码。请仔细检查网格数据的代码。
