@fengqiangboy Set the EnableDropShadow property of your ChildWindow to false. All properties are listed and described on Wiki https://github.com/punker76/MahApps.Metro.SimpleChildWindow/wiki/ChildWindow#properties

@punker76 Thank you for your answer.

I have set the EnableDropShadow property to false, but it doesn't work. Here is my childwindow xaml :

<simpleChildWindow:ChildWindow x:Class="ElectronicCigarette.CustomizeViews.DisplayEdit"
                               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                               xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                               xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
                               xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
                               xmlns:local="clr-namespace:ElectronicCigarette"
                               xmlns:simpleChildWindow="clr-namespace:MahApps.Metro.SimpleChildWindow;assembly=MahApps.Metro.SimpleChildWindow"
                               Padding="15" Title="TestChild 1" ShowCloseButton="True" AllowMove="True"
                               EnableDropShadow="False">

    <StackPanel Margin="20">
        <StackPanel Orientation="Horizontal">
            <Button Content="Import Image" Margin="5" />
            <Button Content="Export Image" Margin="5" />
            <Button Content="Reset To Default" Margin="5" />
        </StackPanel>
    </StackPanel>
</simpleChildWindow:ChildWindow>

And I show the childwindow like this :

private void EditBtnClick(object sender, RoutedEventArgs e)
        {
            ChildWindowManager.ShowChildWindowAsync(Window.GetWindow(this), new DisplayEdit());
        }

@fengqiangboy Just added your sample to the demo and it works... so it must be something else in your scenario. Do you use the latest version? And which MahApps version?

@punker76 Sorry, I did not make it clear, it dose work, but I want make the background translucent like this. https://user-images.githubusercontent.com/658431/28338630-deacb9ca-6c09-11e7-8bdf-054fb008afd6.png And my MahApps version is 1.5.0, MahApps.Metro.SimpleChildWindow version is 1.4.0 .

@fengqiangboy ah, got it. I will update the Wiki for this, cause I must change this. Before the default was a freezed SolidColorBrush with Gray2 from MahApps and Opacity=0.8. This brush cause some trouble in thread scenarios. So I removed it and uses Gray3 as default for the OverlayBrush.

You can set this at your ChildWindow in Xaml to reenable it.

    <simpleChildWindow:ChildWindow.OverlayBrush>
        <SolidColorBrush Color="{StaticResource Gray2}" Opacity="0.8" />
    </simpleChildWindow:ChildWindow.OverlayBrush>
