What exactly do you mean with "rank", are you using an SQL database ?

Solution 1

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.
