SketchFlow how to set button enabled true/false with behavior

Question

Hi, I was trying to figure out if it is possible to set the Enabled property of a button with a ChangeProperty behavior in SketchFlow/ExpressionBlend. It doesn't appear that the Enabled property is available in the behavior. thanks! Bill

Here is xaml that does what you mention above (in silverlight). It works the same way in WPF. The property is named IsEnabled if that is the source of confusion:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"
    x:Class="SilverlightApplication7.MainPage"
    Width="640" Height="480">

    <Grid x:Name="LayoutRoot" Background="White">
        <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Height="58" Margin="225,124,0,0" VerticalAlignment="Top" Width="79"/>
        <Button Content="Button" HorizontalAlignment="Left" Margin="225,230,0,207" Width="50">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="Click">
                    <ei:ChangePropertyAction TargetName="button" PropertyName="IsEnabled" Value="False"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
        </Button>
    </Grid>
</UserControl>
