如何使用rowexpander插件Extjs 4.1.1在网格中展开行 [英] How to expand row in a grid using rowexpander plugin Extjs 4.1.1

问题描述

如何使用rowexpander插件在网格中展开行？我在我的控制器中使用以下代码

 'editbasicinfotitlegrid gridview'：{
 afterrender：this.expandAll 
} 
 
 expandAll：function（）{
 
 var titlesGrid = Ext.getCmp（'editBasicInfoTitleGrid'）; 
 var expander = titlesGrid.getPlugin（'myRowExpander'）; 
 console.log（titlesGrid.plugins [0]）; 
 expander.toggleRow（0）; 
 
} 
  

但是这段代码给我以下错误

 未捕获TypeError：无法调用方法'down'null 
  

$所以我找到了它的解决方案。RowExpander的toggleRow（）函数只能在 viewready Grid的事件。在调用此函数而不是 afterrender 为我工作。

How to expand row in a grid using rowexpander plugin? I am using the following code in my controller

'editbasicinfotitlegrid gridview' : {
            afterrender:this.expandAll
 }

expandAll: function(){

    var titlesGrid = Ext.getCmp('editBasicInfoTitleGrid');     
    var expander = titlesGrid.getPlugin('myRowExpander');
    console.log(titlesGrid.plugins[0]);
    expander.toggleRow(0);

}

But this code gives me the following error

Uncaught TypeError: Cannot call method 'down' of null 

解决方案

So I have found its solution.The toggleRow() function of RowExpander works only on viewready Event of grid.So calling this function on viewready instead of afterrender worked for me.
