I'm trying to program an Installation dialog.
What I've done is using a custom action, and when user click next on this dialog , installer will check the input and pop some alert about the information.
But my boss wants that the tip will reveal automatically at the right of the input text, so when the user finish one text and navigate to the next text, a tip will reveal if the input is not correct.
Seems updating a dialog is impossible, at least is there a way to reveal the tip on the dialog (not pop an alert) when user click next?
