#439 – Using a DropShadow with a Border, part II

I described earlier how you can use two sibling Border elements to end up with the effect of a Border with a DropShadow.  We did this because specifying a DropShadowEffect for a Border will lead to all of the child elements contained in the Border getting the same drop shadow.

A cleaner way to avoid the drop shadows on the child elements is to just specify a value for the Background property of the original parent Border, so that it becomes opaque.

            <Border Margin="10" BorderBrush="DarkGray" BorderThickness="1" CornerRadius="4"
                    Background="{x:Static SystemColors.ControlLightLightBrush}">
            	<Border.Effect>
            		<DropShadowEffect/>
            	</Border.Effect>
                <StackPanel Orientation="Vertical" Margin="5" Visibility="Visible">
                    <Label Content="Rounded corners are everywhere"/>
                    <Button Content="Push Me" Padding="30,5" Margin="5" HorizontalAlignment="Center"/>
                </StackPanel>
            </Border>


You can get some nice effects by using the combination of a gradient fill for the background along with a drop shadow.

#436 – Using a Drop Shadow with a Border

If you specify a DropShadowEffect for a Border, all elements within the border will get a drop shadow.

        <Border Margin="10" BorderBrush="Black" BorderThickness="1">
            <Border.Effect>
                <DropShadowEffect/>
            </Border.Effect>
            <StackPanel Orientation="Vertical" Margin="5">
                <Label Content="Staying within borders"/>
                <Button Content="Do It"/>
            </StackPanel>
        </Border>


If you want the drop shadow around only the Border, you can create two sibling borders–one that has the drop shadow but no content and one that has the content and no drop shadow.

        <Grid>
            <Border Margin="10" BorderBrush="Black" BorderThickness="1" Background="White">
                <Border.Effect>
                    <DropShadowEffect ShadowDepth="2"/>
                </Border.Effect>
            </Border>

            <Border Margin="10" BorderBrush="Black" BorderThickness="1">
                <StackPanel Orientation="Vertical" Margin="5">
                    <Label Content="Staying within borders"/>
                    <Button Content="Do It"/>
                </StackPanel>
            </Border>
        </Grid>
