Set the MaskType of TextEdit as Boolean

I have a TextEdit in my DevExpress Xtragrid.

I want to set the Mask Type of Tex开发者_Python百科tEdit as Boolean

How can I do it ?

Isn't it easier and event a better solution to implement a Combobox in your XtraGrid? A detailed example on Comboboxes in Xtragrid can be found here.
