[WiX-users] How to set default value based on a condtition

[Bimali P. <bim...@gm...>]

Hi all,

I have a new dialog screen introduced into the main installation flow.
This contains a check box which should be set to uncheck by default.

but this check box should be unchecked and disabled when the feature X is
not selected.

I can enable or disable based on feature selection.

But my problem scenario is :
    Select feature X and go to the screen and check the "checkbox"
    Go back to feature tree and unselect feature X
    proceed to the screen... The check box is Checked and disabled... ( this
should be unchecked and disabled)

How can i set back the checked status ??
my checkbox control is like below

<Control Id="InstallSQLExpressCheckBox" Type="CheckBox" X="10" Y="50" Width=
"330"

Height="18" CheckBoxValue="0" Property="INSTALLSQLEX"

Text="!(loc.InstallSQLExpressSelectionCheckBox)" >

<!-- Enable/Disable control according to database feature selection -->

<Condition Action="enable" ><![CDATA[&Database=3]]></Condition>

<Condition Action="disable" ><![CDATA[&Database<>3]]></Condition>
