possible way to disable controls at runtime?

Question

Is there a way to disable UI controls while I'm doing some actions like checking database availability? Now it's like this:

<Control Id="Next" Type="PushButton">
    <Publish Event="DoAction" Value="CheckDBConnection" Order="3">
        <![CDATA[SQL_SERVER <> "" AND SQL_USER <> "" AND SQL_PASSWORD <> ""]]>
    </Publish>
    <Publish Event="DoAction" Value="Confirm_OverwriteDatabase" Order="2"/>
    <Publish Event="NewDialog" Value="VerifyReadyDlg" Order="1"/>
</Control>

When CheckDBConnection is executing, all controls are alive, but doesn't do anything. It will be more accurate to disable them while performing background action.

Use Conditions with enable\disable Actions, based on the desired properties:

<Control Id="{Id}" Type="{Type}">
     <Condition Action="enable" ><![CDATA[SOMEPROPERTY = SomeValue]]></Condition>
     <Condition Action="disable"><![CDATA[SOMEPROPERTY <> SomeValue]]></Condition>
</Control>

when I change property, control doesn't change its state. I need to refresh dialog or something – phantasm Sep 03 '13 at 10:25

I've tried twin dialogs already, it doesn't seem to help - when I switch to the second dialog, event queue for this control resets, so I'm unable to reach `VerifyReadyDlg` – phantasm Sep 03 '13 at 10:35

Thanks to @vitaliy-zadorozhnyy, I was able to come up with an extra weird code that I dont't understand myself. But it works.

...
...

<Property Id="DBCHECK_INPROGRESS" Value="0" />
<Property Id="DBCHECK_NOTINPROGRESS" Value="0" />

...
...

<Control Id="{Id}" Type="{Type}">
    <Condition Action="enable"><![CDATA[DBCHECK_INPROGRESS <> 1]]></Condition>
    <Condition Action="disable"><![CDATA[DBCHECK_INPROGRESS = 1]]></Condition>
</Control>

{insert those conditions for any control you want to disable during action}

...
...


<Control Id="Next" Type="PushButton">
    <Condition Action="enable"><![CDATA[DBCHECK_INPROGRESS <> 1]]></Condition>
    <Condition Action="disable"><![CDATA[DBCHECK_INPROGRESS = 1]]></Condition>

    <Publish Event="DoAction" Value="SetInProgress">1</Publish>
    <Publish Property="TEMP_INPROGRESS" Value="[DBCHECK_INPROGRESS]">1</Publish>
    <Publish Property="DBCHECK_INPROGRESS" Value="[TEMP_INPROGRESS]" />

    <Publish Event="DoAction" Value="CheckDBConnection"/>

    <Publish Event="DoAction" Value="SetNotInProgress">1</Publish>
    <Publish Property="TEMP_NOTINPROGRESS" Value="[DBCHECK_NOTINPROGRESS]">1</Publish>
    <Publish Property="DBCHECK_NOTINPROGRESS" Value="[TEMP_NOTINPROGRESS]" />

    {other events}

</Control>

and custom actions (JScript) are simple:

function SetInProgress_CA() {
    Session.Property("DBCHECK_INPROGRESS") = "1";
}
function SetNotInProgress_CA() {
    Session.Property("DBCHECK_INPROGRESS") = "0";
}
