Thanks Mog. It's nice to know this is resolved in SL3 (unfortunately I'm stuck with SL2 for now!).

Cheers.

Hi, arrgh

I use the latest silverlight build to run your code, it displayed as expected, this issue has been fixed.

thanks.

Yes, I agree with you.

Hi Davide,

Thanks for answering. I realize it works in code, and will work around this some other way. However it still is a bug that should be addressed as it prevents you from using it in a control template like I'm doing.

Hi,

if you set the Color properties in code behind it works.

I've was working on a color picker control when I came across this problem. Here is the simplest example. The following causes an exception:

     <Rectangle>
        <Rectangle.Fill>
            <SolidColorBrush>
                <SolidColorBrush.Color>
                    <Color A="255" R="255" G="255" B="255" />
                </SolidColorBrush.Color>
            </SolidColorBrush>
        </Rectangle.Fill>
    </Rectangle>

While this does not:

     <Rectangle>
        <Rectangle.Fill>
            <SolidColorBrush Color="#FFFFFFFF">
            </SolidColorBrush>
        </Rectangle.Fill>
    </Rectangle>

I'd hoped to use template binding for the red / green / blue values in my control, which is why the second markup would be unsuitable.
