麻烦大家帮忙看看这段代码有什么错误？一运行就报索引超出范围！

Answer 1

GridItem gi = this.gridOrderStat.SelectedItems[0];
gi没有获取到值吧

Answer 2

 Make sure all your column are exists. 
 Such as 
 OrderID ,OrderType ,POCode  etc...

Answer 3

运行就报索引超出范围..很明显 gi 为空 木有值， 你断点 看看 gi 有值么

Answer 4

将你的asp控件改成html控件，然后通过onclientclick时间来获取就ok拉
