Blinking TextBlock

Closed 6 years ago.
I'm trying to make the foreground of a label blink. I tried the following code but I get the following exception and I don't know how to solve it.
'System.Windows.Media.Animation.ColorAnimation' animation object cannot be used
to animate property 'Foreground' because it is of incompatible type
'System.Windows.Media.Brush'.
Using this XAML:
<Label Content="{Binding Path=SendingAlert, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
Foreground="Transparent"
HorizontalAlignment="Right">
<Label.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsSending, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
Value="True">
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard
Storyboard.TargetProperty="Foreground"
Duration="0:0:0.5">
<ColorAnimation From="Transparent" To="Red" AutoReverse="True" RepeatBehavior="Forever"/>
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
<!--<DataTrigger Binding="{Binding IsSending}" Value="False">
<Setter Property="Foreground" Value="Transparent"/>
</DataTrigger>-->
</Style.Triggers>
</Style>
</Label.Style>
</Label>
and where
public bool IsSending
{
get { return !CanDoActions; }
}
private string _sendingAlert = "sending";//string.Empty;
public string SendingAlert
{
get { return _sendingAlert; }
set
{
_sendingAlert = value;
OnPropertyChanged(() => SendingAlert);
}
}
Any idea of how to fix this?

The Foreground property is of type Brush, which is different from an object of type Color
You can use a ColorAnimiation to animate an object of type Color, but not of type Brush, so to animate your foreground brush, you need to set the property to the Brush.Color, like this:
Storyboard.TargetProperty="(Foreground).(SolidColorBrush.Color)"
