Hi,
In our feature selection dialog we are using SelectionTree control.
The selection tree shows only two features: featureA and featureB.
When no feature is selected the 'Next' button should not allow the user to
continue further. It should be disabled.
Here is the relevant markup for 'Next' button
<Control Id="NextButton" Type="PushButton" X="230" Y="318" Width="66"
Height="18" Text="[ButtonText_Next]">" TabSkip="no" Default="yes" >
<Condition Action="disable">NOT((&FeatureA=3) OR
(&FeatureB=3))</Condition>
<Condition Action="enable">(&FeatureBA=3) OR (&FeatureB=3)</Condition>
<Subscribe Event="SelectionNoItems" Attribute="disable" />
<Publish Event="DoAction" Value="FindRelatedProducts">1</Publish>
<Publish Event="NewDialog" Value="ConfirmInstallForm">1</Publish>
</Control>
Subscribing to SelectionNoItems does not seem to work, hence explicit
conditions were added to enable or disable the next button. This seems to
take effect but does so in a delayed fashion. If the user removes selections
next button does not change state. But if the user then presses 'Back'
button and then the 'Next' button he sees the 'Next' button disabled. How
does one go about enabling or disabling the 'Next' button as soon as
selections change?
Thanks for any information.
