Change edit control input type dynamically

Hi all,

I used an edit control in a window. I try to change its input type according to user's choice.
For example,

when user choice 1 from combobox edit control input type must be date
in choice 2 edit control input type must be numeric
in choice 3 edit control input type must be text etc..

try (not tested):
control1..InputType=typInputDate
control1..InputMask="YYYY/MM/DD"

thanks.
