推荐答案

为了得到一个项目的等级，你必须对列中的数据进行排序。



因为你不想对gridview进行排序;



1.将列数据复制到数组

2 。对数组进行排序

3.遍历gridview行并找到数组中列的索引并将其放入rank列。

In order to get the rank of an item you will have to sort the data in the column.

As you do not want to sort the gridview;

1. copy the column data to an array
2. sort the array
3. walk the gridview rows and find the index of the column in the array and put that into the rank column.
