Silverlight Toolkit Accordion - Change color

Question

Hi, In the toolkit, I can't figure out how to change the color of the text under the selected section. It is gray and looks like it is disabled. What do I change to display it in the default color?

Thanks!

          <layoutToolkit:AccordionItem.Content>
          <TextBlock>
            The Accordion is a control that allows you to provide multiple panes and display them.<LineBreak/>
            There are several selection modes, so you can decide if only one pane can be open, <LineBreak/>
            or multiple.<LineBreak/>
            It is also possible to adjust the order in which the panes open and close:<LineBreak/>
            Simultaneous or close first. <LineBreak/>
            <LineBreak/>
            The Accordion is implemented as an itemscontrol that contains AccordionItem controls. <LineBreak/>
            Each AccordionItem control has a template for its Header and its Content. <LineBreak/>
          </TextBlock>
        </layoutToolkit:AccordionItem.Content>
      </layoutToolkit:AccordionItem>
      <layoutToolkit:AccordionItem Header="2. AutoSize" Template="{StaticResource ajaxTemplate}">
        <TextBlock>
          It also supports filling to a specific height or width. <LineBreak/>
          To do so, either set a Height (or Width) or use a VerticalAlignment <LineBreak/>
          (or HorizontalAlignment) of 'Stretch'. <LineBreak/>
          The Accordion will now always fill to that space. If more than one pane <LineBreak/>
          may be opened, space is divided equally among them.
          <LineBreak/>
          Whether you fill to height or width is determined by the ExpandDirection property.<LineBreak/>
          An accordion will is able to expand to Down, Up, Left and Right directions.
        </TextBlock>
      </layoutToolkit:AccordionItem>
      <layoutToolkit:AccordionItem Header="3. Template parts" Template="{StaticResource ajaxTemplate}">
        <TextBlock>
          The accordion uses AccordionItems that can be fully templated.<LineBreak/>
          In order to 'reveal' contents slowly, an ExpandableContentControl is used. <LineBreak/>
          That control has a percentage property that can be animated. A value of 1 <LineBreak/>
          means that the content is completely shown.<LineBreak/>
          <LineBreak/>
          AccordionItem animates this property using a keyspline to get a nice <LineBreak/>
          easing-in effect. You can retemplate AccordionItem and create your own <LineBreak/>
          transitions!<LineBreak/>

Answer 1

I don't have the Toolkit installed on my machine but looking at your problem I have a few suggestions for you to try.

Option 1
Looking at the Accordion Control Template you have supplied you can modify the ExpandableContentControl's style. It current has a Foreground hardcoded to "DarkGray".

This is the line I'm talking about (search for Foreground=DarkGray)

<layoutToolkitPrimitives:ExpandableContentControl x:Name="ExpandSite" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1" Percentage="0" Background="#FFD3DEEF" RevealMode="{TemplateBinding ExpandDirection}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" Padding="2" Margin="1" FontFamily="{TemplateBinding FontFamily}" FontSize="12" FontStretch="{TemplateBinding FontStretch}" FontStyle="{TemplateBinding FontStyle}" FontWeight="{TemplateBinding FontWeight}" Foreground="DarkGray" HorizontalAlignment="Stretch" HorizontalContentAlignment="Left" VerticalAlignment="Stretch" VerticalContentAlignment="Top"/>

Option 2
An easier fix is to set the Foreground color of each of the TextBlocks in your AccordianItems. They will only use the DarkGray defined in the ExandableContentControl if the value isn't overridden by the actual content you supply.

For example you should be able to supply Foreground=Red on your Textblock as so:

 <layoutToolkit:AccordionItem Header="3. Template parts" Template="{StaticResource ajaxTemplate}">
    <TextBlock Foreground=Red>
      The accordion uses AccordionItems that can be fully templated.<LineBreak/>
      In order to 'reveal' contents slowly, an ExpandableContentControl is used. <LineBreak/>
      That control has a percentage property that can be animated. A value of 1 <LineBreak/>
      means that the content is completely shown.<LineBreak/>
      <LineBreak/>
      AccordionItem animates this property using a keyspline to get a nice <LineBreak/>
      easing-in effect. You can retemplate AccordionItem and create your own <LineBreak/>
      transitions!<LineBreak/>
    </TextBlock>
  </layoutToolkit:AccordionItem>
