I just started working on an installer my company is creating and we are using WiX. During installation, we ask for the installer’s name and email address. The “Next” button is disabled until both of those fields are no longer empty. However, the button doesn’t become enabled until focus is changed from the last field edited. I would like to enable the button as soon as both fields have something in them. Here’s what I’ve got so far:

<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)">
    <Condition Action="disable"><![CDATA[UNAME = "" OR EMAIL = ""]]></Condition>
    <Condition Action="enable"><![CDATA[UNAME <> "" AND EMAIL <> ""]]></Condition>
</Control>

Any and all help will be greatly appreciated. Thank you.

    This is not supported by Windows Installer. Control conditions are not evaluated as you type in an edit box.

    A solution would be a dummy Validate button next to your edit box. The user can click it after typing in the edit box so the focus is changed and control conditions evaluated.

    Another solution would be to use an external UI which evaluates control conditions as you type. Some commercial setup authoring tools have this feature built-in.
