System.TimeSpan formatting

[Guest]

Hi guys

I have a problem trying to format a TimeSpan value in a custom grid like I would format a DateTime (through a format string). It seems impossible, I always get the standard "hh:mm:ss" formatting insead of "hh:mm", for instance. Any ideas? Would appreciate your help

Cheers

Unfortunately there's no format specifier for a TimeSpan. You could
use:

string hourMinute = String.Format("{0:n2}:{0:n2}", ts.Hours,
ts.Minutes);

(Untested, but you get the idea._

Hi

thx for the idea but it wouldn't help because I need the TimeSPan to be formatted automatically through a format string; this is happening in a grdi column. I have a custom edit control which shows the right hh:mm format but I see no way to format its string representation..

No, it's not going to work like that, I'm afraid

I suspect you'll find there's *some* way of formatting values in an
arbitrary fashion (just as booleans end up as checkboxes) but it may
well be more effect than you want to go to.

One alternative might be to hide the "real" grid column and have
another column which is set using row/column changes (i.e. it's
computed, but in a more complex way than just using an expression).
