i'm trying to implement windows store application with transparent background.
in my xaml i wrote:
<Page
x:Class="App4.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:App4"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" Background="Transparent">
but the background is black
Did you try adding Opacity within your Grid?
<Grid>
<Grid.Background>
<SolidColorBrush Color="Black" Opacity="0.5"/>
</Grid.Background>
</Grid>
Reference: How do you override the opacity of a parent control in WPF?

I made a simple app that does nothing. It inly displays a NavigationView with two items and a TextBlock as its content. This is the code:
<Page
x:Class="test.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:test"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<NavigationView>
<NavigationView.MenuItems>
<NavigationViewItem Content="First Item" />
<NavigationViewItem Content="Second Item" />
</NavigationView.MenuItems>
<TextBlock Style="{StaticResource HeaderTextBlockStyle}" Text="Welcome to my Page"/>
</NavigationView>
</Grid>
</Page>
My app looks like this:
Why is there extra space at the top of the TextBlock? And how to remove that space? I know it is possible because the News app uses NavigationView and there is no vertical margin. Here is its screenshot:
You need to set the AlwaysShowHeader property to False:
<NavigationView AlwaysShowHeader="False">
This is called out in the docs here, though the new preview version seems to change this behavior currently and not show any header by default.
Could be a user control completely transparent?
<UserControl
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"
xmlns:ed="http://schemas.microsoft.com/expression/2010/drawing"
mc:Ignorable="d"
x:Class="MainWindow.UserControl3"
Width="600" Height="600">
<Grid x:Name="LayoutRoot" Background="Transparent"/>
</UserControl>
if I execute the previous code the result is a black window, not transparent why?
Thanks
I would like to have an image in this grid that serves as a background. Any attempt till now at inserting an image control resulted in the image being on top of the buttons while I would like it to be on the back.
<Page

xmlns:local="using:ZimmerFrei_v0._1"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid >
<Button x:Name="btnNearMe"
Content="Near Me"
HorizontalAlignment="Left"
Margin="99,181,0,0" VerticalAlignment="Top"
Height="76"
Width="216"
Click="btnNearMe_Click"/>
<Button x:Name="btnBestOffers"
Content="Button"
HorizontalAlignment="Left"
Margin="99,312,0,0"
VerticalAlignment="Top"
Height="76" Width="216"
Click="Button_Click"/>
<Image />
</Grid>
The simplest thing that you can do here is to give your Grid an Image Brush. Simply head to the Brush section in your properties windows and select the Tile Brush there. To the ImageSource property specify the image you want.

Hope this solves your problem.
My form contents are displayed in a Grid inside of a Scrollview on a page.
<phone:PhoneApplicationPage
x:Class="DS.Mobile.Pages.FormAppPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
>
<ScrollViewer >
<Grid x:Name="_canvas" Background="Gainsboro">
</Grid>
</ScrollViewer>
</phone:PhoneApplicationPage>
Normally the content can be viewed without any scrolling action, but windows provides a dramatic over scrolling behavior anyway if you drag across the screen surface. How do you prevent this over scroll behavior?
I am Using silverlight4 I have developed one page when I navigate to this page from Other Silverlight Page the Position is at the bottom of the page .I need to set the Focus on top of the silverlight Page.I am not using ScrollViewer on my Page.
Open MainPage.xaml file and replace the code with the following.
<UserControl xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" x:Class="ScrollViewerControl.MainPage"
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">
<Grid x:Name="LayoutRoot" Background="White">
<ScrollViewer Height="300" Width="300" Name="scrollViewer1"
VerticalScrollBarVisibility="Auto"
HorizontalScrollBarVisibility="Auto">
<ScrollViewer.Content>
<StackPanel>
' Content Here
</StackPanel>
</ScrollViewer.Content>
</ScrollViewer>
</Grid>
</UserControl>
set the ScollViewer offset to zero like
scrollViewer1.ScrollToVerticalOffset(0);
then your vertical scroll will always be on Top.
