I thought I was over this but a change request just came in.

The mask has to be changed to a simple time format hh:mm. The problem is that it has to be possible to enter negative times to. Since the "-" only works with "n" i tried "{LOC}-nn:nn" (that the minute block could be greater than 60 is not a problem since i check it anyway) but when i enter 00:00 I cant get past the ":" which is strage. The Column is a simple string type. Strange thing is when i use "99:99" as a mask it works just fine but i cant get negative values. The only way this worked was entering "{LOC}-n99:99" as mask. This works but when i enter a value (defualt is 0:00) it looks just ugly 0__:00.

Is there any way to hide the padding or a better mask?

Hi,

Thanks for the Advice it could be done by setting the MaskDisplay- and MaskDataMode to MaskMode.IncludeLiterals. 

So if anyone has a similar Problem here is what I did:

column.MaskInput = "nnnn:nn";

column.MaskDisplayMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.IncludeLiterals;

column.MaskDataMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.IncludeLiterals;

I tried to use the Mask "nnn#:##" but it wasn't possible to enter the time the way i liked (from right to left) so i just used a check in the Leave Event

Thanks
