Maintaining default visual properties with ControlTemplate

Answer 1

Hey Greg,

You can't inherit ControlTemplate from theme style. But you don't have to. Use DataTemplates to achieve what you want. Here is a quick example:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"&gt;
  <Page.Resources>
  <Style TargetType="{x:Type ToolTip}">
  <Style.Triggers>
    <EventTrigger RoutedEvent="ToolTip.Loaded">
      <BeginStoryboard>
        <Storyboard TargetProperty="Opacity">
          <DoubleAnimation From="0" To="0.8" Duration="0:0:0.5" />
        </Storyboard>
      </BeginStoryboard>
    </EventTrigger>
  </Style.Triggers>
  </Style>

<DataTemplate x:Key="ToolTipContentTemplate">
<StackPanel>
      <Label FontWeight="Bold" Background="DarkSlateBlue" Foreground="White">
        WpfApplication1
      </Label>
      <Label>
        Click to create another button
      </Label>
    </StackPanel>
</DataTemplate>
  </Page.Resources>

  <Grid>  
<Button Content="Hello">
<Button.ToolTip>
<ToolTip ContentTemplate="{StaticResource ToolTipContentTemplate}">
  <ToolTip.Content>
    Doesn't matter in this case
  </ToolTip.Content>
</ToolTip>
</Button.ToolTip>
</Button>
  </Grid>
</Page>

You can paste it to Kaxaml, and test it.

Hope this helps.
