I am using drag and drop reorder code from:

https://codeasp.net/articles/asp-net/65/reorder-list-using-jquery-and-asp-net

It's simple and works great. 

How can I update additional fields in the same DB table. 

I need to update the following fields in my SQL DB: "UpdatedOn" (datetime), and "UpdatedBy" (string). 

I tried modifying the SP, but it updated every row in the DB. 

I need to update only the row that was dropped.

thank you very much!!
