I'm getting a "Specified cast is not valid" error that does not point
to the line with the code in error, but instead :An unhandled exception
was generated during the execution of the current web request.
Information regarding the origin and location of the exception can be
identified using the exception stack trace below.
The stack trace is just a lot of system class stuff with no real
explanation of where the error is. Wondering the best way to decipher a
stack trace in such a case.
thanks

Can you post the stack trace from the exception?

The stack trace indicates that the error is occurring in
dg1_ItemDataBou nd. Set a breakpoint in that method and step through it.
You should be able to determine where the invalid cast is occurring.
I hope this helps.

I put a breakpoint there, but I can't find where a break window for
debugger is. The only choices for Stepping is Step In and Step over,
which does nothing to show me what line the error is.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
