Invoke custom action on WIX when changing value in Combox

Stuck with combo box and user action in WIX installer.

I have a drop down box containing several values. I want to show some text on the screen (unique for each item in the drop-down list) when the user selects a value from this drop-down list.

In .Net, we can do this easily because we have different predefined events. But on WIX, I do not see such an event.

Has anyone encountered the same problem? Or you can direct me on how I can do this.
