I am using a UltraWinGrid and for some numeric columns i set the MaskInput

It working for a long time.

Currently i implemented appdomain in my application (my windows application opened in a separate appdomain, other than the current)

Now the input mask is not working at all. I am unable to input numbers in that

I am struggling for the last 2 days to fix this

There is no code change related to the input mask

I dont know whether the problem is because of appdomain implementation

 Expecting ideas and help to fix this

Thanks
