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

You cannot use a brush as a color.
So instead of
<SolidColorBrush x:Key="bglight" Color="#1A6CAA" />
use
<Color x:Key="bglight">#1A6CAA</Color>

I have noticed in the November CTP that you have to define resources before
you use them (literally before they are referenced in the XAML file).

I'm sure this has changed from earlier versions, and as yet I haven't seen
any mention as to why.

There are some other problems with your XAML, but if you change it to:

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

You should be able to make some progress.

I agree, but that still doesn't solve my problem it still says it can't
find the resouce named bglight

Thanks

Yes! you're right, it's like good old Pascal where I had to make all
functions and procedures before de main code
Thanks Doug!

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,

Hi again, just one more question if you don't mind, I got all the colors in
the window resouces, now how do I access them to change their value? I've
thought that I could just call them by their x:Key

Thanks

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).
