Trigger an animation on Grid Focus/Click? - wpf

Question

I have a two text box's one purely for animation and another to use. The animation works fine apart from when the text box is not focused i would like it to reverse the animation, which is possible if you use exit actions, but this then does not allow me to use the text box underneath as it sees that as an exit action. So i wondered if it was possible to only reverse the animation when the grid is pressed? or even exclude the other text box?
how can i achieve this? Here is my code.
<TextBlock Margin="250.449,182.112,374.044,0" Text="Hint Text" Foreground="{StaticResource brushWatermarkForeground}"
Visibility="{Binding ElementName=txtUserEntry, Path=Text.IsEmpty, Converter={StaticResource BooleanToVisibilityConverter}}" Height="19.725" VerticalAlignment="Top" />

Answer 1

Wrap both TextBoxes in a container (a Grid will suffice):
<Grid x:Name="TextBoxes">
<TextBox Name="txtUserEntry" Background="Transparent" BorderBrush="{x:Null}" Margin="250.449,182.112,352.952,0" Height="25.689" VerticalAlignment="Top" BorderThickness="0" />
<TextBox x:Name="textBox" Text="Floating Label Text" Height="25.689" VerticalAlignment="Top" Margin="250.449,182.112,352.952,0" Style="{DynamicResource TextBoxStyle1}" BorderThickness="1" Foreground="#FF8B8B8B" Background="White"/>
</Grid>
That way you can use the IsKeyboardFocusWithin property of the containing Grid, which would be True no matter which one of your TextBoxes is focused.
In order to change as less as possible of your existing code, you could simply change your Trigger and make it a DataTrigger, and bind it to the IsKeyboardFocusWithin property of the Grid ancestor.
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource TextBox.Focus.Border}"/>
</Trigger>
<DataTrigger Binding="{Binding IsKeyboardFocusWithin, RelativeSource={RelativeSource AncestorType={x:Type Grid}}"
Value="True">
<Trigger.EnterActions>
<BeginStoryboard Storyboard="{StaticResource Storyboard1}" />
<BeginStoryboard Storyboard="{StaticResource StoryboardTextAnimation}" />
</Trigger.EnterActions>
</DataTrigger>
Add the ExitActions that you need, and they should only execute when both TextBoxes are not focused.
