Vista - Color

Hi, I have an application with a color for some parts of the UI and I want
that the user is able to change that color so I tried to create a "style" of
that color and in code I have only to change that color and it would change
all the UI, so I did:


<GradientStop Color="{StaticResource bglight}" Offset="1"/>
....
<Window.Resources>
<SolidColorBrush x:Key="bglight" Color="#1A6CAA" />
</Window.Resources>

but the problem here is that it says that it can't find bglight, what am I
doing wrong here?

Thanks

Yeah, this is a change specifically in the Nov. CTP actually. StaticResource
no longer supports forward looking resource resolution. They are resolved
according what resources are available in the current lexical scope while
parsing the XAML document.

HTH,

I touched on this in
http://blogs.msdn.com/nickkramer/arc...20/482915.aspx (second
paragraph). Long story short, we couldn't make for references work all the
time, so we decided not to support them.

Actually, in the November CTP, there's at least one case where we still
support forward references; at some point we'll stop supporting that as
well. The case we still support is one resource referring to another
resource in a resource dictionary (at least inside compiled xaml, not sure
about uncompiled), e.g.:
<Something.Resources>

<SomeObject x:Key="A" Property="{StaticResource B}/>

<SomeObject x:Key="B"/>

</Something.Resources>

That's a forward reference, we support that by accident today and will do
the correct, no forward references allowed behavior in a future CTP when we
correct StaticResource to behave lexically (see blog).
