AdornedElement Properties in a Trigger
- by Chris Nicol
I have an Adorner in XAML that I'm using for ErrorValidation. Basically I have a grid that I want to display on two conditions (if the "AdornedElement" IsFocused or IsMouseOver).
Below is a code snippet where I'm binding - successfully - to the IsFocused of the AdornedElement, but as you can tell that only solves 1/2 the conditions. Now I can't pass another binding into the converter, nor can I create a property that handles both (needs to be XAML only solution).
<AdornedElementPlaceholder
x:Name="errorAdorner" />
...
<Grid
x:Name="ErrorDetails"
Visibility="{Binding ElementName=errorAdorner, Path=AdornedElement.IsFocused, Converter={StaticResource BooleanToVisibilityConverter}}" />
...
What I want to do is use triggers to handle this, the only problem is I can't access the AdornedElement's properties on a trigger.
Something like this ...
<Trigger
SourceName="errorAdorner"
Property="AdornedElement.IsFocused"
Value="True">
<Setter
TargetName="ErrorDetails"
Property="Visibility"
Value="Visible" />
</Trigger>
This would also help as part of what I want to do is trigger animations, rather than just setting the visibility.
Any help would be great.
