Question

我正在使用MaterialDesignInXAML作为WPF应用程序.我有一个PopupBox,我想更改图标.目前它默认为DotsVertical,我想把它作为一个DotsHorizontal.

我试了以下没有运气.

<materialDesign:PopupBox PlacementMode="BottomAndAlignRightEdges" StaysOpen="False">
    <materialDesign:PopupBox.Content>
        <materialDesign:PackIcon Kind="DotsHorizontal" />
    </materialDesign:PopupBox.Content>
    <StackPanel>
        <TextBlock Text="Test1" />
        <TextBlock Text="Test2" />
        <TextBlock Text="Test3" />
    </StackPanel>
</materialDesign:PopupBox>

提前致谢!

为了更改图标并保留当前样式，请使用以下命令：

<materialDesign:PopupBox PlacementMode="BottomAndAlignRightEdges" StaysOpen="False">
     <materialDesign:PopupBox.ToggleContent>
         <materialDesign:PackIcon Kind="DotsHorizontal" 
                                Foreground="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=materialDesign:PopupBox}, Path=Foreground}"                        />
         </materialDesign:PopupBox.ToggleContent>
    <StackPanel>
        <TextBlock Text="Test1" />
        <TextBlock Text="Test2" />
        <TextBlock Text="Test3" />
    </StackPanel>
</materialDesign:PopupBox>
