I guess you want to hide the edit button for all updated row. If so you can do the following to achieve this
When a row is updated checked, store the key values for the updated row in a Session variable.
Add a PreRender event handler to the grid.
In the pre-render event of the grid, traverse the rows of the grid and compare their key values to the values saved in the Session variable.
Whenever you find a match, access the editbutton for that row and hide it.
You can refer the following documentation which explains how to persist the selected rows server-side on sorting/paging/filtering/grouping. Use the same logic and make necessary modification.
