[WPF] Rounded Window Drop Shadow Problem

Question

Hi,

I have a WPF window in my project, where the window will have a corner radius of 26. Using Drop Shadow, there are square corners of the shadow which looks odd. I have used as following...

<Border BorderThickness="1" CornerRadius="26" > <Border.Effect> <DropShadowEffect BlurRadius="15" Direction="-90" RenderingBias="Quality" ShadowDepth="2" Color="#FCFCFC" /> </Border.Effect>

Is there any way so that the shadow becomes rounded as the window is???

Answer 1

By setting a border around the main border, I get a rounded shadow :

<Border BorderBrush="Transparent" BorderThickness="10" CornerRadius="25" Background="Transparent">  
                    <Border BorderBrush="Red" BorderThickness="4" CornerRadius="25" Name = "MainBorder">  
 <Border.Effect>   
    <DropShadowEffect BlurRadius="15" Direction ="-90" RenderingBias ="Quality" ShadowDepth ="2" Color ="Red" />  
</Border.Effect>                          
                        <Border.Background>  
                            <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">  
                                <GradientStop Color="Yellow" Offset="0.0" />  
                                <GradientStop Color="Red" Offset="0.25" />  
                                <GradientStop Color="Blue" Offset="0.75" />  
                                <GradientStop Color="LimeGreen" Offset="1.0" />  
                            </LinearGradientBrush>  
                        </Border.Background>  
                    </Border>  
   </Border>
