Hello,
Could you help me ??
I have to modify a binary file (containing dates) : I want to access all records ie add,delete,and modify the dates in the binary file.

Hi, I was wondering if there is a way to have a
BoundColumn in DataGrid, but not display it? Basically I
would like to have a primary key hidden (and I need this
for edits and deletes).
I know I could store DataSet in the viewstate or session,
but I was just curios if DataGrid offers something (kind
of like Stringray's grid allowing you to associate a row
with data in a void* )

update then the new values appear.
I noticed that when I put a breakpoint in my update handler everything
works fine. When I take...
