<StackPanel HorizontalAlignment="Center" VerticalAlignment="Top">
<TextBlock Text="Vijaya dhas" FontSize="36" FontWeight="Black"/>
<TextBlock Text="Mobile App Developer Trainee" FontSize="26" FontWeight="SemiBold"/>
<TextBlock Text="Chennai" FontSize="24" FontWeight="Medium"/>
</StackPanel>
If i give like this my out put is:
If I give this into the button content:
<Button Height="200">
<Button.Content>
<StackPanel>
<TextBlock Text="Vijaya dhas" FontSize="36" FontWeight="Black"/>
<TextBlock Text="Mobile App Developer Trainee" FontSize="26" FontWeight="SemiBold"/>
<TextBlock Text="Chennai" FontSize="24" FontWeight="Medium"/>
</StackPanel>
</Button.Content>
</Button>
the out put is:
I don't want change the TextBlock font style. Please give any idea to keep the font style what ever it is.
Here i have attached my list box example for your review:
Without Using Button:
Using Button Content:
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!--TitlePanel contains the name of the application and page title-->
<StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
<TextBlock x:Name="ApplicationTitle" Text="List Example" Style="{StaticResource PhoneTextNormalStyle}"/>
<TextBlock x:Name="PageTitle" Text="Example" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
</StackPanel>
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="2,0,2,0" Background="#FFE5E5E5">
<TextBlock Text="List Box With Button Content" Margin="0,150,0,0" FontSize="26" Foreground="Red" VerticalAlignment="Top" />
<ListBox HorizontalAlignment="Left" Margin="0,180,0,0" Name="listBox1" VerticalAlignment="Top" Width="480" ItemsSource="{Binding Content, Mode=TwoWay}">

<DataTemplate>

To Get rid of the button's default padding, margin and styles etc, set its template to "{x:Null}"
<Button Height="200" Template="{x:Null}">
<Button.Content>
<StackPanel>
<TextBlock Text="Vijaya dhas" FontSize="36" FontWeight="Black"/>
<TextBlock Text="Mobile App Developer Trainee" FontSize="26" FontWeight="SemiBold"/>
<TextBlock Text="Chennai" FontSize="24" FontWeight="Medium"/>
</StackPanel>
</Button.Content>
</Button>
I'm trying to put two Grids in a DataTemplate.
I'm getting the following error with my code shown below.

A data template can only have one visual tree but you are defining two grids. If you want the two grids to appear next to each other or one below the other, wrap them in a StackPanel and set the property Orientation accordingly.
<DataTemplate>
<StackPanel Orientation="Vertical">
<Grid>[...]</Grid>
<Grid>[...]</Grid>
</StackPanel>
</DataTemplate>
I have the following code:
<ListBox x:Name="FavList">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Button x:Name="PlayPause" Style="{StaticResource IconButton}" HorizontalAlignment="Left" Margin="2,2,0,2" Width="72" Click="PlayPause_Click" BorderThickness="0">
<ImageBrush x:Name="PlayPauseImage" ImageSource="Assets\Images\Play.png" />
</Button>
<TextBlock x:Name="myStreamName" Margin="84,8,8,0" TextWrapping="Wrap" Text="{Binding Name, FallbackValue='Test'}" Height="29" VerticalAlignment="Top" FontSize="20" FontWeight="Bold"/>
<TextBlock x:Name="myStreamDescription" Margin="84,37,8,8" TextWrapping="Wrap" Text="{Binding About, FallbackValue='Testing'}" FontSize="16"/>
<TextBlock x:Name="myStreamURL" Text="{Binding URL}" Visibility="Collapsed" />
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu>
<toolkit:MenuItem x:Name="DeleteFavorite" Header="{Binding Path=LocalizedResources.DeleteFavButton, Source={StaticResource LocalizedStrings}}" Click="DeleteFavorite_Click" />
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
When I have the MenuItem Header equal to what I have there now, I keep getting invalid XAML errors. When I just put in header="Delete" Everything is fine.
Any ideas why this is happening?
I'm going through the Windows 8 Bing Translator Walkthrough
I was able to follow everything except the XAML part. I'm very new to XAML. Below is what the walkthrough appears to recommend, however VS2012 indicated the markup is invalid, and the error displayed says "the property "content" is set more than once". Is this the only issue? Where this is set more than once?
<GridView ItemTemplate="{StaticResource TweetTemplate}" SelectionMode="None" ItemsSource="{Binding tweets}"></GridView>
<DataTemplate x:Key="TweetTemplate">
<Grid>
<Rectangle Fill="#FFDA713F" HorizontalAlignment="Left" Height="115" Margin="10,11,0,0"
VerticalAlignment="Top" Width="455" RadiusX="20" RadiusY="20"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="50"
Margin="176,12,0,0" TextWrapping="Wrap" x:Name="txtTweet"
Text="{Binding Title}" VerticalAlignment="Top" Width="277" FontSize="12"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="50"
Margin="176,72,0,0" TextWrapping="Wrap" x:Name="txtTrans"
Text="{Binding translatedText}" VerticalAlignment="Top" Width="277"
FontSize="12"/>
<Image Source="{Binding ImageUri}" HorizontalAlignment="Left" Height="89"
Margin="20,20,0,0" VerticalAlignment="Top" Width="116"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="17"
Margin="24,109,0,0" TextWrapping="Wrap" Text="{Binding Author}"
VerticalAlignment="Top" Width="150" FontSize="10"/>
</Grid>
</DataTemplate>
...and no sooner do I post the question, I find the answer. the above needs to be arranged as follows:
Note that from the example in the link provided above the author used RefreshAppBarButtonStyle. This was changed to AppBarButtonStyle. I;m not sure I fully understand the xaml page yet, but at least I have a working framework to diagnose.
<Page.Resources>
<DataTemplate x:Key="TweetTemplate">
<Grid>
<Rectangle Fill="#FFDA713F" HorizontalAlignment="Left" Height="115" Margin="10,11,0,0" VerticalAlignment="Top" Width="455" RadiusX="20" RadiusY="20"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="50" Margin="176,12,0,0" TextWrapping="Wrap" x:Name="txtTweet" Text="{Binding Title}" VerticalAlignment="Top" Width="277" FontSize="12"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="50" Margin="176,72,0,0" TextWrapping="Wrap" x:Name="txtTrans" Text="{Binding translatedText}" VerticalAlignment="Top" Width="277" FontSize="12"/>
<Image Source="{Binding ImageUri}" HorizontalAlignment="Left" Height="89" Margin="20,20,0,0" VerticalAlignment="Top" Width="116"/>
<TextBlock Foreground="White" HorizontalAlignment="Left" Height="17" Margin="24,109,0,0" TextWrapping="Wrap" Text="{Binding Author}" VerticalAlignment="Top" Width="150" FontSize="10"/>
</Grid>
</DataTemplate>
</Page.Resources>
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<GridView ItemTemplate="{StaticResource TweetTemplate}" SelectionMode="None" ItemsSource="{Binding tweets}"></GridView>
</Grid>
<Page.BottomAppBar>
<AppBar x:Name="bottomAppBar" Padding="10,0,10,0">
<Grid>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock x:Name="txtPrompt" Text="Search Term: " Height="24" FontSize="24"></TextBlock>
<TextBox x:Name="txtSearchTerm" Width="300" Height="24"></TextBox>
<Button Style="{StaticResource AppBarButtonStyle}" Click="Button_Click_1" />
</StackPanel>
</Grid>
</AppBar>
</Page.BottomAppBar>
Hope this is also of use to someone else.

I am getting the following error with my code shown below.
Error:
The property 'Content' is set more than once
Code:
<controls:PanoramaItem Header="headlines">
<TextBlock Text="{Binding Tones}" />
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding Tones}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<Image Source="{Binding ImageUrl}" Height="75" Width="100"
Margin="12,10,9,0" VerticalAlignment="Top"/>
<StackPanel Width="311">
<TextBlock Text="{Binding Title}" TextWrapping="Wrap"
Style="{StaticResource PhoneTextLargeStyle}" />
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</controls:PanoramaItem>
A PanoramaItem can only have one child control but you currently have a TextBlock and a ListBox. To fix this, simply add another parent control to hold the TextBlock and ListBox (such as a StackPanel or a Grid). For example:
<controls:PanoramaItem Header="headlines">
<grid>
<TextBlock Text="{Binding Tones}" />
<!--Double line list with image placeholder and text wrapping-->
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding Tones}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<!--Replace rectangle with image-->
<Image Source="{Binding ImageUrl}" Height="75" Width="100" Margin="12,10,9,0" VerticalAlignment="Top"/>
<!--<Rectangle Height="100" Width="100" Fill="#FFE5001b" Margin="12,0,9,0"/>-->
<StackPanel Width="311">
<TextBlock Text="{Binding Title}" TextWrapping="Wrap" Style="{StaticResource PhoneTextLargeStyle}"/>
<!--<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>-->
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</grid>
</controls:PanoramaItem>
