Now. I use an asp.net webforms datagrid to view the data. At one stage the value in this column is 635838861561284513. I do (in theory) send this value through as a parameter on the url when I click a custom link on this grid. The value is added to the url as follows:
Now I noticed upon debugging that the value
"<%# Eval("BATCH_NO") %>" comes through as 635838861561284500 and not 635838861561284513.
But the value displays correctly in the grid!!
Can anyone explain why this is happening?
