AutomaticColor Issue

[Fábio Witt jagnow]

Hey..

In the application that i'm developing, i'm using the ColorPicker and i needed to use the Color Transparent. Since i didn't knew how i could achieve that, i searched here in the forum and found this thread, that is very similar to my case.
http://www.telerik.com/community/forums/silverlight/colorpicker/selectedcolor-doesn-t-update-ui.aspx

I've downloaded the example and i saw that the AutomaticColor property wasn't working declaratively in the xaml. I realized it was made in an old build. Then i updated the references to the lastest build.. It worked fine...

After that, i tried to do the same on my application but it not worked as i expected, not even in the codebehind. Then i went to see what was different between my code and the one in the example, the only thing that i found was the Expression_Dark theme that i was using. I added the reference to the Expression_Dark theme on the example project, changed the ColorPicker to change the style to E.Dark and suddenly it stopped working. I tought then it could be the Colors that in the Expression_Dark theme are different, but then i tried colors that belong to the theme like #FF416100 and #FF1F497D, but that did not worked.

So here's the code that i've changed:

private void Button_Click(object sender, RoutedEventArgs e)
{
    //picker.AutomaticColor = Color.FromArgb(255, 65, 97, 0);
    picker.AutomaticColor = Color.FromArgb(255, 31, 73, 125);
    picker.SelectedColor = Color.FromArgb(255, 216, 214, 203);
}

<telerik:RadColorPicker telerik:StyleManager.Theme="Expression_Dark"
                                    x:Name="picker" />

Maybe you guys can give me a light or another approach. 

Thanks,
Fábio Witt.
