You need to handle the DropDownList SelectedIndexChanged. Inside that event get the selected value of that DropDownList.

Then loop through all the rows of GridView and inside that remove that particular value from all the DropDownLists.

On the other hand, while updating the value of DropDownList, you need to get the previous option value from some data source or something. So, what you can do is that, initially when you get all the items, just store that in Session. While updating all the options inside the SelectedIndexChanged, just compare the data from the Session and add/remove from DropDownLists accordingly.
