I would like to change the background of my grid to white when you hover over or select it. I'd also like to change the color of the text inside at the same time to black. This is specific to one page only, so it would need to be applied with an XKey or something as a guess. The grid starts with a transparent background, also.
I'm really struggling to find the direction for this. Please let me know if you have any ideas or links!
Here's my code:
<GridView.ItemTemplate>
<DataTemplate>
<Grid VerticalAlignment="Top" HorizontalAlignment="Left" Width="335" Height="152">
<StackPanel Orientation="Horizontal" Margin="2,2,2,2" VerticalAlignment="Top" HorizontalAlignment="Left">
<StackPanel Margin="13,0,13,0" Orientation="Vertical" VerticalAlignment="Top" HorizontalAlignment="Left">
<StackPanel Orientation="Horizontal" VerticalAlignment="Bottom">
<TextBlock Style="{StaticResource SmallText}" Text="{Binding Town}" />
<TextBlock Style="{StaticResource SmallText}" Text=", "/>
<TextBlock Style="{StaticResource SmallText}" Text="{Binding State}"/>
<TextBlock Style="{StaticResource SmallText}" Text=", "/>
<TextBlock Style="{StaticResource SmallText}" Text="{Binding Postcode}"/>
</StackPanel>
</StackPanel>
</StackPanel>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
Thanks for any help.
It seems like you would probably want to modify your GridView's ItemContainerStyle and change its background and visual states to match your requirements. Check my answer to an earlier question related to restyling items here to learn how to extract and modify these styles and templates.

I'm new in developing applications for Windows Phone 8. I have a case that I need to add itens in a list, but I think will be nice if I could do something like the button "add an account", like in Windows Phone settings. See:
How can I do this?
I know how to do the accounts List. I can use LongListSelector, like this example:
<phone:LongListSelector x:Name="llsAccounts"
LayoutMode="List" Margin="0,150,0,0" SelectionChanged="llsAccounts_SelectionChanged">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="12,2,0,4" Height="105" Width="432">
<!--Replace rectangle with image-->
<Border BorderThickness="1" Width="99" Height="99" BorderBrush="#FFFFC700" Background="#FFFFC700"/>
<StackPanel Width="311" Margin="8,-7,0,0">
<TextBlock Text="{Binding AccountName}" TextWrapping="Wrap" Margin="10,0" Style="{StaticResource PhoneTextExtraLargeStyle}" FontSize="{StaticResource PhoneFontSizeLarge}" />
<TextBlock Text="{Binding DetailsAccount}" TextWrapping="Wrap" Margin="10,-2,10,0" Style="{StaticResource PhoneTextSubtleStyle}" />
</StackPanel>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
I could resolve my problem using two LongListSelectors: one LongListSelector only for the "add an account" item and the second LongListSelector for the all added accounts. But this will be messy for me... it's not the right way.
Thanks!
There are quite a few ways you can to do this. You can just add a static <StackPanel> for your Add an Account follow by the LLS. Or you can use the LLS header/footer tags.
LLS header/footer example:
<phone:LongListSelector Name="lls">
<phone:LongListSelector.ListHeader>
<TextBlock Text="this is a header"/>
</phone:LongListSelector.ListHeader>
<phone:LongListSelector.ListFooter>
<TextBlock Text="this is a footer"/>
</phone:LongListSelector.ListFooter>
</phone:LongListSelector>
I have a ListView and I want to put a border around each item in the ListView. Microsoft doesn't seem to have a system theme for the Border element.
What is the recommended way to theme the border so it looks good on Dark and Light theme?
Here is my ListView
<ListView ItemsSource="{Binding Products}" Header="My Header" Margin="10,5,10,5">
<ListView.HeaderTemplate>
<DataTemplate>
<TextBlock Text="My Header" Style="{ThemeResource HeaderTextBlockStyle}" />
</DataTemplate>
</ListView.HeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<Border>
<StackPanel>
<TextBlock Text="{Binding Name}"
Style="{StaticResource TitleTextBlockStyle}" />
<TextBlock Text="TextBlock 1:"
Style="{StaticResource ControlHeaderTextBlockStyle}" />
<TextBox Text="{Binding TextBlock1}"/>
<TextBlock Text=" TextBlock 2:"
Style="{ThemeResource ControlHeaderTextBlockStyle}"/>
<TextBox Text="{Binding TextBlock2}"/>
</StackPanel>
</Border>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
**************Edit 1****************
I should have put this. I want it in a Universal App targeted at WP8.1 and Windows 8.1, not just phone.
You probably just want the standard foreground color, right? (dark for light, light for dark). That would be the PhoneContrastForegroundBrush.
<Border BorderThickness="1" BorderBrush="{StaticResource PhoneContrastForegroundBrush}">
The previous answers lead me to look at system brushes and I found ApplicationForegroundThemeBrush, which I believe will work.
I have a ListBox with this template in it.
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Key="Template">
<StackPanel Margin="0,10">
<Border BorderBrush="Black" BorderThickness="1" Background="#FFFFC000" Width="460" MinHeight="76">
<StackPanel Margin="4,4,-4,-153">
<TextBlock Text="{Binding }" HorizontalAlignment="Center" VerticalAlignment="Top" Foreground="Black" TextWrapping="Wrap"/>
<TextBlock " Text="{Binding Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Top" Foreground="Black" TextWrapping="Wrap"/>
</StackPanel>
</Border>
</StackPanel>
</DataTemplate>
</phone:PhoneApplicationPage.Resources>
Yet I have to force set a Width and Height on the Border otherwise it makes like Width and Height of "2".
It is like it does not understand I have 2 TextBlock inside it and won't expand to fill both of them.
This leaves me with having to put a fixed height and width in what I don't like as if the text is too big it gets cutoff.
You can toss out your StackPanel's because you don't need them, they're also what's keeping your wrapping from working, you need a panel like a Grid for that. The negative Margin's also isn't something you'd normally see in a DataTemplate for a ListBox so I'd guess you have some other funky layout stuff going on from that sort of practice elsewhere up the tree.
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Key="Template">
<Grid Margin="0,10">
<Border BorderBrush="Black" BorderThickness="1" Background="#FFFFC000"/>
<TextBlock TextWrapping="Wrap"
HorizontalAlignment="Center" Margin="4,4,-4,-153">
<Run Text="{Binding }"/><LineBreak/>
<Run Text="{Binding Mode=OneWay}"/>
</TextBlock>
</Grid>
</DataTemplate>
</phone:PhoneApplicationPage.Resources>
So unless I'm missing something somewhere this should fix you up as the Grid will handle the sizes of its children for you and consume the space necessary in its parent. However if there's something else in your structure pushing stuff around and won't let it consume that space it should invoke your Wrapping.
Hope this helps :)
I am developing a windows 8 metro app in which I have listbox which contains a set of textblocks and a Image.
<ListBox x:Name="lstbxbStudents" Background="Transparent" ItemContainerStyleSelector="{StaticResource ItemStyleSelector}" ScrollViewer.VerticalScrollBarVisibility="Auto" ItemTemplate="{StaticResource LandscapeItemTemplate}" Height="476" SelectionChanged="lstbxbProducts_SelectionChanged_1" Style="{StaticResource ListBoxStyle1}" HorizontalAlignment="Left" Width="901">
</ListBox>
For that image ImgCmt I have set the source of the Image static inside the datatemplate of the listbox.
<Page.Resources>
<CollectionViewSource x:Name="cvs2" IsSourceGrouped="true" />
<!-- TODO: Delete this line if the key AppName is declared in App.xaml -->
<x:String x:Key="AppName">Students Screen</x:String>
<DataTemplate x:Key="LandscapeItemTemplate" >
<StackPanel Orientation="Horizontal">
<StackPanel Width="30"></StackPanel>
<StackPanel Width="120" Orientation="Horizontal">
<TextBlock Text="{Binding stunum}" VerticalAlignment="Center" HorizontalAlignment="Left" />
</StackPanel>
<StackPanel Width="350">
<TextBlock Text="{Binding studsc}" HorizontalAlignment="Left" />
</StackPanel>

</StackPanel>
</StackPanel>
</DataTemplate>

my objective is that I want to change the source of the image to different image source(change the image) in codebehind depnding upon some condition for that I need to access the control present inside a datatemplate of listbox in metro app ?
How can I do this :

This is a common question. We've all asked it at least once. The problem is that these controls don't have a unique name, because they are in a repeater. As a result, you cannot use the logical tree in XAML. The logical tree is what lets you call things by name. Instead, you need to use the visual tree in XAML. The visual tree is what lets you access everything on the screen including the dynamically rendered elements that adorn controls and populate repeaters. Because the visual tree is so big and because a repeater repeats, you still have to constrain the scope of the visual tree so you can reliably locate the control you want to find. I hope this makes sense.

Hi I am trying to get my UI have scrolling in partial page having a list. Here's my code -

Doesnt seem to be scrolling at the List area. i seem to have figured out that the issue is with Scrollviewer not able to interact where ListBox exists. I verified that the scrolling is happening perfectly fine by setting IsHitTestVisible property of ListBox to be false.
Can someone help me out!
Answering my own question! Just as AMR commented it, I figured out that I don't need the scroll viewer, I just set the height of ListBox and scrolling worked fine! :)
