DataGrid Edit problem after sort

One of my users called yesterday and asked me to look into a problem on
a datagrid. Everytime she clicked on a row to edit, another row would
appear in it's place. After a little analysis it appeared that this
only happened after the datagrid was sorted. I placed the row in edit
mode. Almost everytime that I clicked the Cancel button on that row I
experienced a random shuffling of rows.

I am using ViewState and DataView Sort to hold the sort value . I used
Response.Write to display the value while debugging. The value seems to
be correct.

I did a quick search on Google. It seems that this is a common problem.
Some of these posts were a couple of years old. Has a solution for this
been discovered?
