I have a stackpanel which i fill with an textblock. I have an stackpanel.resources. I tried setting the background to transparent but it will make the whole style invisible (but the text not) and i tried using opacity. This does make my stackpanel slightly transparent but also the text within the stackpanel.
The stackpanel looks like this:
<StackPanel Orientation="Vertical" Margin="550,25,0,0">
<Border>
<TextBlock OpticalMarginAlignment="None">
<Run FontSize="24" Text="Product"></Run><LineBreak/>
<Run FontSize="18" Text="Artikelnummer: "></Run><LineBreak/>
<Run FontSize="18" Text="Omschrijving: "></Run><LineBreak/>
<Run FontSize="18" Text="Eenheid: "></Run>
</TextBlock>
</Border>
<StackPanel.Resources>
<Style TargetType="Border">
<Setter Property="Background" Value="#287d37" />
<Setter Property="Margin" Value="5" />
<Setter Property="Width" Value="400" />
<Setter Property="Height" Value="105" />
</Style>
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="White" />
<Setter Property="Margin" Value="5" />
</Style>
</StackPanel.Resources>
</StackPanel>
Does anyone know how i can achieve my goal of setting the background of the stackpanel to something like opacity 0.25 but the text inside that stackpanel not?
Thanks in advance!
Specify the alpha channel (the first byte) in the case of hardcoded colors, or the opacity if you're using a brush:
<StackPanel Background="#44287d37">
...
</StackPanel>
or
<StackPanel>
<StackPanel.Background>
<SolidColorBrush Color="Blue" Opacity=".25"/>
</StackPanel.Background>
...
</StackPanel>

I have a custom template for a flyout, and it works fine on about half of our systems, but it completely breaks on the other half.
Here's what the menu looks like when it works:
And here's what it looks like when it doesn't work... the semi-transparency is completely black, and the contents of the menu itself are completely off the screen:
You can ignore how the second screenshot is wider and how the stuff behind the menu looks different. That's just a different resolution and a different set-up, but this issue happens even when they're the same.
As noted in the picture, when the MenuFlyout appears (when I open the menu via clicking the AppBarButton), I need a semi-transparent area to appear in front of the rest of the page. This is accomplished by putting a big rectangle in the flyout's template, causing the shadow behind the flyout to be extended out over the rest of the page.
Here's the code of the button that triggers the flyout to show:
<AppBarButton
x:Name="MenuBtn"
Height="72"
Label="{StaticResource Menu}"
AllowFocusWhenDisabled="False"
Click="MenuBtn_Click"
CornerRadius="0"
Style="{StaticResource AppBarIconButtonStyle}"
TabIndex="9"
Width="72"
Margin="0,0,16,8"
Loaded="MenuBtn_Loaded"
RelativePanel.AlignRightWithPanel="True"
RelativePanel.AlignBottomWithPanel="False">
<AppBarButton.Flyout>
<MenuFlyout x:Name="HbgMenuFlyout" MenuFlyoutPresenterStyle="{StaticResource MenuFlyoutPresenterStyle}" Opening="MenuFlyout_Opening" Closing="HbgMenuFlyout_Closing" Closed="MenuFlyout_Closed">
<MenuFlyoutItem x:Name="SelectRoomBtn" x:Uid="HbgMenu_Select_Room" Style="{StaticResource MenuFlyoutItemStyleDark}" Click="SelectRoomBtn_Click" /> <!-- mobile only -->
<MenuFlyoutItem x:Name="PhysicianProfileBtn" x:Uid="HbgMenu_Physician_Preferences" Style="{StaticResource MenuFlyoutItemStyleDark}" Click="Physician_Preferences_Click" />
<MenuFlyoutItem x:Name="SystemSettingsBtn" x:Uid="HbgMenu_Settings" Style="{StaticResource MenuFlyoutItemStyleDark}" Click="SystemSettingsBtn_Click" />
<MenuFlyoutItem x:Name="HomeBtn" x:Uid="HbgMenu_Home" Style="{StaticResource MenuFlyoutItemStyleDark}" Click="HomeBtn_Click" />
<MenuFlyoutItem x:Name="LogoutBtn" x:Uid="HbgMenu_Logout" Style="{StaticResource MenuFlyoutItemStyleDark}" Click="LogoutBtn_Click" />
</MenuFlyout>
</AppBarButton.Flyout>
</AppBarButton>
Here's the code for the style attached to the MenuFlyout:
<Style x:Key="MenuFlyoutPresenterStyle" TargetType="MenuFlyoutPresenter">
<Setter Property="RequestedTheme" Value="Dark"/>
<Setter Property="Background" Value="Gray" />
<Setter Property="BorderBrush" Value="Gray" />
<Setter Property="BorderThickness" Value="0,0,0,0" />
<Setter Property="Padding" Value="0" />
<Setter Property="VerticalAlignment" Value="Stretch" />
<Setter Property="ScrollViewer.HorizontalScrollMode" Value="Disabled" />
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" />
<Setter Property="ScrollViewer.VerticalScrollMode" Value="Auto" />
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
<Setter Property="ScrollViewer.IsHorizontalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.ZoomMode" Value="Disabled" />
<Setter Property="MinWidth" Value="{ThemeResource FlyoutThemeMinWidth}" />
<Setter Property="MaxWidth" Value="2000" />
<Setter Property="MinHeight" Value="{ThemeResource MenuFlyoutThemeMinHeight}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="MenuFlyoutPresenter">
<controls:FlyoutGridControl />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And here's the code for that control:FlyoutGridControl:
<UserControl
x:Class="CardiologyApp.Controls.FlyoutGridControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="400" >
<RelativePanel x:Name="RootGrid" HorizontalAlignment="Stretch">
<Rectangle x:Name="Shield" Width="2000" RelativePanel.AlignRightWith="MenuFlyoutPresenterScrollViewer" PointerPressed="Rectangle_PointerPressed" />
<ScrollViewer x:Name="MenuFlyoutPresenterScrollViewer"
Width="516"
RelativePanel.AlignRightWithPanel="True"
HorizontalAlignment="Right"
Background="Gray"
AutomationProperties.AccessibilityView="Raw">
<ItemsPresenter />
</ScrollViewer>
<Border x:Name="MenuFlyoutPresenterBorder"
VerticalAlignment="Stretch"
RelativePanel.Below="MenuFlyoutPresenterScrollViewer"
RelativePanel.AlignRightWithPanel="True"
Height="1000"
Background="Gray"
Width="516"
/>
</RelativePanel>
The workaround for the developers is to comment out the in the control:FlyoutGridControl.
Any suggestions on how to make the behavior consistent across systems? We're all on Windows 10 Enterprise.
MenuFlyout is not suitable for pop-up layer fixed on the right sidebar. In higher system versions, MenuFlyout is not limited by the size of the application window, which will invalidate your layout.
According to your actual display picture, SplitView should be a control that better meets your needs.
This is a simplified layout structure:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<CommandBar VerticalAlignment="Top" HorizontalAlignment="Stretch">
<AppBarButton/>
</CommandBar>
<SplitView DisplayMode="CompactOverlay" OpenPaneLength="516"
PanePlacement="Right" x:Name="AppSplitView" Grid.Row="1">
<SplitView.Pane>
<Grid>
<!--Used to display list items-->
<ListView/>
</Grid>
</SplitView.Pane>
<SplitView.Content>
<Grid>
<!--Main content display area-->
</Grid>
</SplitView.Content>
</SplitView>
</Grid>
If you want to apply the above code, you need to use ListViewItem in ListView to replace your MenuItem.
If you need to show your options, just set:
AppSplitView.IsPaneOpen = True;
For more information about SplitView and its display effect, you can check this document:

I have a quick (and most likely) easy question for which I unfortunately do not find a suitable solution. My requirements are as follows:
For the purpose of creating a navigation bar, I want to stack some buttons. For this purpose, I am using a stack panel.
Between each of the buttons, I want to have some space. I could of course set the margin for every button, however I find this solution not very robust and instead want to define the margin centrally.
What I therefore did is I defined a style within the stack panel and set the margin once. This works great with one issue: For the button I would love to use a style provided by Materialdesigninxaml. When I however set the style to the button, the margin style gets ignored.
Has anyone an idea or do I need to make use of a workaround?
Thank you guys for your help.
Here is my sample code which works as no Materialdesigninxaml style is defined:
<StackPanel.Resources>
<Style TargetType="{x:Type Button}">
<Setter Property="Margin" Value="0 10 0 0"/>
<Setter Property="Height" Value="50"/>
<Setter Property="Width" Value="150"/>
</Style>
</StackPanel.Resources>
<Button>
<StackPanel Orientation="Horizontal">
<materialDesign:PackIcon Kind="Database" VerticalAlignment="Center"/>
<TextBlock Text="BUTTON 1"/>
</StackPanel>
</Button>
This is my code with a specified Materialdesigninxaml style which does not work:
<StackPanel.Resources>
<Style TargetType="{x:Type Button}">
<Setter Property="Margin" Value="0 10 0 0"/>
<Setter Property="Height" Value="50"/>
<Setter Property="Width" Value="150"/>
</Style>
</StackPanel.Resources>
<Button Style="{DynamicResource MaterialDesignFlatButton}">
<StackPanel Orientation="Horizontal">
<materialDesign:PackIcon Kind="Database" VerticalAlignment="Center"/>
<TextBlock Text="BUTTON 1"/>
</StackPanel>
</Button>
I am trying to get the MenuFlyout to align bottom-left of the button. I can achieve this if i put the button at the left of the screen, but if the button is anywhere else the MenuFlyout is always centered right under the button. I suspect that I have to create a template and change a property in there but I do not know what I need to change to achieve this.
I've pasted my xaml below with a note of where i suspect I need to make the change. I am new to xaml, any help or guidance will be much appreciated. Thanks!

In your MenuFlyout_Opened method, you can explicitly call ShowAt(UIElement, Point) method.
This first parameter will probably be your buttonMenuFlyout; the second one, your offset which might roughly be new Point(0, buttonMenuFlyout.ActualHeight).
I want to create a grid of images without any margin between them. I tried to achieve this through a GridView. If there is an easier way, please let me know.
I found this answers on StackOverflow:
https://stackoverflow.com/a/10492464
https://stackoverflow.com/a/23817931/5739170
And ended up with this code:
<Page.Resources>
<Style x:Key="MyGridViewItemStyle" TargetType="GridViewItem">
<Setter Property="Padding" Value="0" />
<Setter Property="Margin" Value="0" />
<Setter Property="BorderThickness" Value="0" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridViewItem">
<GridViewItemPresenter ContentMargin="0" Padding="0" Margin="0" BorderThickness="0"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Page.Resources>
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<StackPanel>
<GridView ItemsSource="{x:Bind FieldList}" Margin="0,50,0,0" Padding="0" BorderThickness="0" ItemContainerStyle="{StaticResource MyGridViewItemStyle}" IsItemClickEnabled="True" ItemClick="OnItemClick">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:Field">
<Image Width="20" Height="20" Margin="0" Source="{x:Bind ImagePath}"/>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
<TextBlock x:Name="text">Hallo!</TextBlock>
</StackPanel>
</Grid>
But there is still a margin left:
Screenshot
I have also tried to use negative margins but when I use them clicks aren't recognized correctly anymore.
How can I remove the margins?
Seems like the GridViewItem has a default MinWidth of 44px.
You can set it to 0 via your GridViewItemStyle:
<Setter Property="MinWidth" Value="0" />
EDIT: it also has a default MinHeight, you might want to set that to 0 as well.
The code below should work:
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="Margin" Value="0"/>
</Style>
</GridView.ItemContainerStyle>
Your code is good. If you add a Grid in the DataTemplate (with a Background), you will see there is no margin between grids :
<DataTemplate x:DataType="data:Field">
<Grid Background="Red">
<Image Width="20" Height="20" Margin="0" Source="{x:Bind ImagePath}"/>
</Grid>
</DataTemplate>
Your problem is the following : you set a fixed size for Image control wich all of them is in a container, but the container doesn't have a fixed, so images are centered in the container.
I see two solutions. First is to remove the fixed size for Image control and use Strecth property to fill correctly :
<DataTemplate x:DataType="data:Field">
<Image VerticalAlignment="Stretch"
HorizontalAlignment="Stretch"
Stretch="UniformToFill"
Margin="0"
Source="{x:Bind ImagePath}"/>
</DataTemplate>
For the first solution, you must be sure of the filling behavior of the container. You can do something like :
<GridViewItemPresenter ContentMargin="0"
Padding="0"
Margin="0"
BorderThickness="0"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch" />
The second solution is to set a fixed size on the container directly :
<Style x:Key="MyGridViewItemStyle"
TargetType="GridViewItem">
<Setter Property="Padding"
Value="0" />
<Setter Property="Margin"
Value="0" />
<Setter Property="BorderThickness"
Value="0" />
<Setter Property="Width"
Value="20" />
<Setter Property="Height"
Value="20" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridViewItem">
<GridViewItemPresenter ContentMargin="0"
Padding="0"
Margin="0"
BorderThickness="0"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The new Windows 8 metro API still defineds class DataTemplateKey.
However, I can figure out how to use it.
Do you have an example in XAML that shows how it can be used?
Here's an example on how to use DataTemplateKey. Just a note and a reminder : The x:Key attribute will take precedence over the automatic DataTemplateKey that is generated based on the DataType
