我想在我的項目中爲彈出窗口設置陰影。但是當我運行它時,陰影不會出現。 我寫了這個代碼:wpf彈出陰影不顯示
<Popup x:Name="popup" IsOpen="False" Width="200" Height="200" Placement="AbsolutePoint" AllowsTransparency="True" PopupAnimation="Fade" >
<Grid>
<Border BorderThickness="1" Background="#FF4CAAC7" CornerRadius="6" >
<Border.Effect>
<DropShadowEffect BlurRadius="15" Opacity="0.8" ShadowDepth="10" Direction="-90" RenderingBias="Quality" />
</Border.Effect>
<StackPanel Orientation="Horizontal">
<Grid Width="200" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" FontWeight="Bold" TextAlignment="Right" Margin="10">Operation was successful</TextBlock>
</Grid>
</StackPanel>
</Border>
</Grid>
</Popup>
設計陰影show.in運行,而不是show.what是問題!
