[wix-users] Message Box in Wix Control & Custom Action

[Ven H]

I have a UI dialog with a Control of type Push button. Is it possible to
display a Message Box with a custom message based on a condition and also
without a condition? (not from a Custom Action).  If yes, please provide a
sample.

Is it possible to display a Message Box from a Custom Action which will be
invoked on a Push button click in a Control of a UI dialog? If yes, please
provide a sample

Please help.
