I have three features in a Selection Tree control. I would like Feature 2 and
3 to be independently selected and installed but if Feature 1 is selected to be
installed I want Feature 2 to be automatically selected since Feature 1 depends
on it. When my Selection Tree is displayed I see:
[-] All Features
[x] Feature 1 (requires Feature 2)
[x] Feature 2
[x] Feature 3
Where [-] represents the icon for "Will be installed on local hard drive"
and [x] represents the icon for "Entire feature will be unavailable".
When I select Feature 1 to be installed I see:
[-] All Features
[-] Feature 1 (requires Feature 2)
[x] Feature 2
[x] Feature 3
But when I select Feature 1, I want Feature 2 to be selected automatically so
it would look like this:
[-] All Features
[-] Feature 1 (requires Feature 2)
[-] Feature 2
[x] Feature 3
I don't want Feature 3 to be automatically selected since it is not required by
Feature 1. Is there a way to do this? This seems like a simple problem but I
could not find any documentation or examples on how to do this. I have tried
to use a condition within Feature2 like the following but the condition never
gets tested since only Feature 1 was selected:
<Feature Id="ProductFeature" Title="All Features" Display="expand"
Level="1">
<Feature Id="Feature1" ConfigurableDirectory="APPLICATIONFOLDER"
Title="Feature 1 (requires Feature 2)" Level="2">
<ComponentRef Id="file1.txt" />
</Feature>
<Feature Id="Feature2" ConfigurableDirectory="APPLICATIONFOLDER"
Title="Feature 2" Level="2">
<ComponentRef Id="file2.txt" />
<Condition
Level="1">MsiSelectionTreeSelectedFeature="Feature1"</Condition>
</Feature>
<Feature Id="Feature3" ConfigurableDirectory="APPLICATIONFOLDER"
Title="Feature 3" Level="2">
<ComponentRef Id="file3.txt" />
</Feature>
</Feature>
If only Feature 1 is selected, is there a way to "tell it" to set the Level
attribute of Feature2 to 1 so that Feature 2 in the Selection Tree displays the
icon showing it will be installed also? If trying to set the Level attribute
of Feature2 is not the right approach, is there another method I can use to
accomplish the behavior I desire?
