Changing foreground color of a TextBox control

Maybe this question is kind of silly but I have no clue how to solve the following (maybe trivial) problem:

I just want to change the foreground color of a TextBox control in Silverlight 4 so that in "Normal" state it is, say, black and in "Disabled" state it should be red.

So far i did the following: I am editing the controls ControlTemplate to manipulate the visual states of the TextBox with the Visual State Manager in Blend 4 but because the text in the textBox is realized as its contentControl I can't find any foreground property to change the color or it to link to a particular visual state respectively.

Again, I simply want to set different foreground colors for different visual states of the TextBox.

Can anybody help me ? Thank you in advance !

You can do a couple things, You can delete the contentpresenter and replace it with a textblock, then with the TextBlock selected go to your Common Properties -> Text and click the little square next to it and choose Template Binding -> Content Which just adds a template binding for content to the control.

Or a quick an easy way is just wrap it in a usercontrol and apply your changes to it instead like

<UserControl>
<ContentPresenter....
</UserControl>

Then just choose the user control object and voila you can set foreground etc.

In the disabled state, you could set the Foreground property of the content control (if the template doesn't contain a content control, you could just wrap it around the content presenter):

<Storyboard>
    <ObjectAnimationUsingKeyFrames BeginTime="0"
                                   Storyboard.TargetName="contentControl"
                                   Storyboard.TargetProperty="Foreground">
        <DiscreteObjectKeyFrame Value="Red" KeyTime="0" />
    </ObjectAnimationUsingKeyFrames>
</Storyboard>
