#914 – Drawing a Border Around an Expander

You can make the boundaries of an Expander control more clear if you draw a border around the control.  The style for an Expander already has a Border element, though it is not visible by default.  You can make it visible by setting the BorderBrush and BorderThickness properties on the Expander.

        <Expander BorderBrush="DarkGray" Margin="0,5">
            <Expander.Header>
                <Image Source="CptBlood-1935.png" Width="51" Height="72"/>
            </Expander.Header>
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
