我有一个弹出窗口,当我点击弹出窗口外的任何地方时我想关闭它.我搜索过,大家都建议我使用属性IsLightDismissEnabled; 然而,如果我在外面触摸,它将只删除pop pop,使所有处于非活动状态的灰色屏幕,就好像它没有完全关闭弹出窗口这是我的代码片段:

 <Popup x:Name="logincontroler" IsOpen="False" Margin="0,190,896,276" IsLightDismissEnabled="True">
            <StackPanel Height="300" Width="470" x:Name="popup" FlowDirection="RightToLeft">
                <Grid Width="470" Background="White" >
                    <Grid.RowDefinitions>
                        <RowDefinition Height="70"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>
                    <RichEditBox Grid.Row="1" Height="250" TextWrapping="Wrap" FontSize="20" Name="notesPopupTextBox" FlowDirection="LeftToRight"/>
                    <StackPanel Grid.Row="0" Orientation="Horizontal" Background="#FFE3E3E5">
                        <Button Name="CanclePopupButton" Content="Cancel" Width="64" Height="64" Click="CanclePopupButton_Click" />
                        <Button Name="ClearNotePopupButton" Content="Clear" Width="64" Height="64" Click="ClearNotePopupButton_Click" />
                        <Button Name="saveNoteButton" Content="Save" Width="64" Height="64" Click="saveNoteButton_Click" />

                        <TextBlock FontWeight="Medium"  FontSize="40" Foreground="#2a2a86" Margin="170 12 0 0">Note</TextBlock>
                    </StackPanel>
                </Grid>
            </StackPanel>
        </Popup>

 private void ShowButton_Click(object sender, RoutedEventArgs e)

        flipView1.IsEnabled = …
