I need to keep disabled Install buton while one field is empty
Hello all! :)

I need to keep disabled Install button on Select Options page until one field is empty. When the user fills this field the Install button should be enabled.
I suppose it's necessary to send message to Select Options window but i don't sure
Couldn't you recommend me something?


why don't you select your field and grey out by default?


I have to manage availability of button "Install" dinamically. "Install" button is disabled until "password" field is NOT blank anymore


You can't have it disabled, but you can have a message box pop-up when the user clicks the next button. Use MinLen=1 and ValidateText or validate with your own custom code in the leave function of the page.
