ExtJs中的GridPanel取每一行其中一个字段的值，急！！！！

[何必为难]

DataTable dt = DbHelperSQL.ExcuteQuery(sql);
for (int i = 0; i < dt.Rows.Count; i++)
{
    string id=dt.Rows[i]["ID"].ToString();
}

我的意思就是从GridPane中取第i行的ID值.Rows[i]["ID"]

 for (var i = 0; i < bGrid.getStrore().getCount(); i++) {
string id=dt.Rows[i]["ID"].ToString();//这里的意思就是取bGrid的每行的ID字段的值，具体写法不知道
}

GridPanel中的第i行的ID字段怎么表示啊

麻烦各位帮忙！！！

[又找到怎么修改昵称了]

bGrid.getStrore().getAt(i).get('ID');

引用 1 楼 orange_shuiguo 的回复:

JavaScript code?1bGrid.getStrore().getAt(i).get('ID');

说这种方法

做循环的时候总是报错：对象不支持此属性或方法！不知道怎么回事

bGrid.getStrore().getAt(i).get('ID');

应该是getStore()
