绑定过后出现'this.grid.store' is null or not an object的错误提示。我觉得问题就是在Load事件上，但是不清楚应该怎么书写才正确。请高手指点。多谢！
代码如下：
var selModel = new Ext.grid.CheckboxSelectionModel();
checkSearchDetailStore=new Ext.data.GroupingStore({
proxy:new Ext.data.HttpProxy(
{
url:"../BackGroundData.aspx",
method:"POST"
}),
reader:new Ext.data.JsonReader(
{
fields:checkSearchDetailFields,
root:"data",
id:"XH"
}),
sortInfo: {field:'XH',direction: "ASC"},
listeners: {
'load': function(store) {
var index = 0;
store.each(function(record) {
if(record.data.YSXXC008 == '1') { //column_name 替换成你的列名， '1' 替换成你的值
selModel.selectRow(index);
}
index++;
})
}
}
});
checkSearchDetailStore.load({params:{module:'checkSearchDetail',tx:number}});
