Set a background image to Listbox item - windows-phone-7

I'm able to set an image to Listbox using the background property.
But how do I set a desirable image as a background to items of the listbox?
Thanks.

You'll have to redefine the ItemTemplate property of the ListBox. If you're not confident with XAML, you should try using Expression Blend.
Here is an example of how you're XAML could look like. I created a new application using the Pivot Template application.
<ListBox x:Name="FirstListBox" Margin="0,0,-12,0" ItemsSource="{Binding Items}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17" Width="432" Height="78">
<StackPanel.Background>
<ImageBrush Stretch="Fill" ImageSource="/Koala.jpg"/>
</StackPanel.Background>
<TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
So the default ItemTemplate uses a StackPanel as main container. What you want to do here, is to set the image as the background of that StackPanel. That's what the following lines stands for:
<StackPanel.Background>
<ImageBrush Stretch="Fill" ImageSource="/Koala.jpg"/>
</StackPanel.Background>
With the above code, you set an ImageBrush as the Background property of the StackPanel.
With that code, each ListBoxItem will display a koala.

Wrapping the listbox item using border and setting the background might help.Follow this sample
<Border Width="380" Height="60" Margin="0,0,0,10" >
<Border.Background>
<ImageBrush ImageSource="Images/menu_bg.png" />
</Border.Background>
<TextBlock Foreground="Black" FontSize="22" Text="{Binding}" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>

Please tell me that how to bind description and schedule name in context menu, either by code or by xaml.
How to bind data in context menu either through code or through xaml?
I create a breadcrumb context menu with binding using the code below. The code you should be interested in is the toolkit:ContextMenu.ItemTemplate section where you specify the bindings. Notice that you can also bind to a command parameter like I do with the index value.
The toolkit:ContextMenu.Template section is not needed. I added this to allow scrolling the items if there are more than will fit on the screen and also to move the menu to the bottom of the screen.
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu x:Name="breadCrumbContextMenu" ItemsSource="{Binding CloudViewModel.BreadCrumbMenuItems}" Opened="ContextMenu_Opened" Closed="Breadcrumb_ContextMenu_Closed">
<toolkit:ContextMenu.Template>
<ControlTemplate TargetType="toolkit:ContextMenu">
<Border Margin="0,700,0,0" BorderThickness="1" >
<ScrollViewer MaxHeight="700">
<ItemsPresenter/>
</ScrollViewer>
</Border>
</ControlTemplate>
</toolkit:ContextMenu.Template>
<toolkit:ContextMenu.ItemTemplate>
<DataTemplate>
<toolkit:MenuItem Click="breadcrumbMenuItem_Click" CommandParameter="{Binding Index}" Padding="0">
<toolkit:MenuItem.Header>
<StackPanel Orientation="Horizontal" Height="40">
<Image Source="{Binding Image}" Width="40" Height="40" />
<TextBlock Text="{Binding Text}" Margin="24,0,0,0" />
</StackPanel>
</toolkit:MenuItem.Header>
</toolkit:MenuItem>
</DataTemplate>
</toolkit:ContextMenu.ItemTemplate>
</toolkit:ContextMenu>

How to set SelectItem Foreground in LongListSelector

i want set the SelectItem Foreground with diff color , in LongListSelector
This is my xaml:
<toolkit:LongListSelector x:Name="locations" Background="Transparent" Margin="0"
GroupViewOpened="LongListSelector_GroupViewOpened"
GroupViewClosing="LongListSelector_GroupViewClosing"
SelectionChanged="locations_SelectionChanged">
<toolkit:LongListSelector.GroupItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</toolkit:LongListSelector.GroupItemsPanel>
<toolkit:LongListSelector.GroupItemTemplate>
<DataTemplate>
<Border Background="{Binding Converter={StaticResource GroupBackground}}"
Width="99" Height="99" Margin="6" IsHitTestVisible="{Binding HasItems}">
<TextBlock Text="{Binding Key}"
FontFamily="{StaticResource PhoneFontFamilySemiBold}"
FontSize="48"
Margin="8,0,0,0"
Foreground="{Binding Converter={StaticResource GroupForeground}}"
VerticalAlignment="Bottom"/>
<Border.Projection>
<PlaneProjection RotationX="-60"/>
</Border.Projection>
</Border>
</DataTemplate>
</toolkit:LongListSelector.GroupItemTemplate>
<toolkit:LongListSelector.GroupHeaderTemplate>
<DataTemplate>
<Border Background="Transparent" Margin="12,8,0,8">
<Border Background="{StaticResource HighlightBrush}"
Padding="8,0,0,0" Width="62" Height="62"
HorizontalAlignment="Left">
<TextBlock Text="{Binding Key}"
Foreground="#FFFFFF"
FontSize="48"
FontFamily="{StaticResource PhoneFontFamilySemiLight}"
HorizontalAlignment="Left"
VerticalAlignment="Bottom"/>
</Border>
</Border>
</DataTemplate>
</toolkit:LongListSelector.GroupHeaderTemplate>
<toolkit:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Margin="20,0">
<TextBlock Text="{Binding n}" Style="{StaticResource PhoneTextExtraLargeStyle}"
FontFamily="{StaticResource PhoneFontFamilySemiBold}"
Margin="12,5"/>
</StackPanel>
</DataTemplate>
</toolkit:LongListSelector.ItemTemplate>
</toolkit:LongListSelector>
the LongListSelector without a "ItemContainerStyle", i don't know how to set a Style Resources, like normal listboxitem.
If you edit your ItemTemplate to use a ContentControl instead of a TextBlock, the selected item will use the phones accent brush (make sure you aren't setting the foreground color for the content control):
<toolkit:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Margin="20,0">
<ContentControl Text="{Binding n}" Style="{StaticResource PhoneTextExtraLargeStyle}"
FontFamily="{StaticResource PhoneFontFamilySemiBold}"
Margin="12,5"/>
</StackPanel>
</DataTemplate>
</toolkit:LongListSelector.ItemTemplate>
To be able to set it to a custom color, I ended up overriding the constructor for TemplatedListBoxItem and set the DefaultStyleKey: DefaultStyleKey = typeof(TemplatedListBoxItem); I then set up a style for TemplatedListBoxItem that matches the ListBoxItem style in System.Windows.xaml except for a different selected item visual state color.

Windows Phone How to Vertical Scroll

I'm just starting out in WinPhone development and can't figure out how to set the vertical scroll. For example i've started a new Pivot App, and this code allows the user to scroll up and d own to see all the entries:
<controls:PivotItem Header="Login">
<!--Double line list with text wrapping-->
<ListBox x:Name="FirstListBox" Margin="0,0,-12,0" ItemsSource="{Binding Items}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17" Width="432" Height="78">
<TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</controls:PivotItem>
Now when, I add my own pivot item, with a stackpanel with more items than can be seen on the screen at any one time, it will not allow me to scroll to see them all. What am I missing here?
Thanks.
Add ScrollViewer over the StackPanel and it will make it scrollable.
The ListBox in the example code that you supplied ha built-in scrolling functionality. However, if you are not using something that already has this scrolling functionality in it, you will have to add a ScrollViewer.
<controls:PivotItem Header="Example">
<ScrollViewer Margin="12,0,12,0">
<StackPanel>
<TextBlock Text="Example1" FontSize="150" />
<TextBlock Text="Example2" FontSize="150" />
</StackPanel>
</ScrollViewer>
</controls:PivotItem>
In a pivot control, if the content is overflowing the vertical page then there should be default "vertical" scrolling available to you.
I had a similar control with list box bounded to property. Having "list" should automatically allow you to scroll.
Don't add a scrollviewer over the stack panel as it would make the scrolling enabled for each list item which you don't want.
<controls:PivotItem Header="all authors" Foreground="#FF0C388A">
<Grid>
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding AllAuthorsList}" Foreground="#FF0C388A">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17" Width="432" Height="Auto">
<TextBlock Tap="TextBlockAuthor_Tap" Text="{Binding}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" Foreground="#FF0C388A"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</controls:PivotItem>

ListBox Style Selected item on windows phone

i would like know how can i add a style when a item of the listbox is selected.
I have the following listbox:
<ListBox x:Name="ListBoxDays"
VerticalAlignment="Top"
ItemTemplate="{StaticResource WeekDayTemplate}"
ItemsSource="{Binding WeekDayList}" />
And i also have a DataTemplate to the listbox.
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Key="WeekDayTemplate">
<StackPanel x:Name="stackPanel" Orientation="Horizontal" Width="400" Margin="12,0,0,10" Height="100" >
<StackPanel VerticalAlignment="Center" Orientation="Vertical">
<TextBlock Text="{Binding WeekDayName}" Style="{StaticResource PhoneTextExtraLargeStyle}" TextWrapping="Wrap" TextTrimming="WordEllipsis" Foreground="{StaticResource PhoneRadioCheckBoxPressedBorderBrush}" UseLayoutRounding="True" />
<TextBlock Text="{Binding ShortDate}" Style="{StaticResource PhoneTextTitle2Style}" TextWrapping="Wrap" TextTrimming="WordEllipsis" Foreground="{StaticResource PhoneBorderBrush}" Margin="25,0,12,0" />
</StackPanel>
</StackPanel>
</DataTemplate>
</phone:PhoneApplicationPage.Resources>
At the moment when i select an item of the listbox no color change happens.
You have to change the style of the template ListBoxItem which the ListBox generates for each of the items that it renders. Your updated template needs to customise the Selected visual state. You can then associate this new template with your ListBox via the ListBox.ItemContainerStyle property.
There is a good tutorial, with sourcecode to download, here:

Scroll PanoramaItem Header in 'wide' PanoramaItem

I'm interested in creating my own 'Hub' Panorama. I've gotten the 'wide' PanoramaItem working, but I'm trying now to mimic the behavior seen in the Marketplace hub, where the PanoramaItem Header scrolls as you move across the hub.
I'm looking for a way for it to smoothly animate to the end of the hub. Has anyone tried this before, or have any suggestions?
I'd imagine it would be something like this:
//OnPanoramaViewChanged
//get X location of viewport
//animate title to X location
However it doesn't appear that the Panorama has a ScrollViewer attached property.
In case you're curious, here's how I made a wide panorama item.
<controls:PanoramaItem ScrollViewer.HorizontalScrollBarVisibility="Visible" Header="movies" Orientation="Horizontal" Width="900">
<controls:PanoramaItem.HeaderTemplate >
<DataTemplate >
<StackPanel>
<TextBlock Foreground="{StaticResource PanoramaHeaderBrush}" Text="{Binding}">
</TextBlock>
</StackPanel>
</DataTemplate>
</controls:PanoramaItem.HeaderTemplate>
<StackPanel>
<!-- line list with image placeholder and text wrapping -->
<ListBox ItemsSource="{Binding Items}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.Template>
<ControlTemplate>
<ItemsPresenter />
</ControlTemplate>
</ListBox.Template>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10">
<Grid Background="{StaticResource ControlTitlesInactivePivotBrush}" Width="173" Height="173" >
<TextBlock FontSize="24" Text="Movie Title (2010)" TextWrapping="Wrap" Style="{StaticResource PhoneTextGroupHeaderStyle}"/>
<Rectangle Fill="White" Height="48" Width="48" HorizontalAlignment="Right" VerticalAlignment="Bottom">
<Rectangle.OpacityMask>
<ImageBrush ImageSource="/Test;component/movie_icn.png" />
</Rectangle.OpacityMask>
</Rectangle>
</Grid>
<TextBlock Text="Movie Title:" Margin="12,0,12,0" Foreground="Black" />
<TextBlock Text="The Title" Margin="12,-6,12,0" Foreground="Gray"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</controls:PanoramaItem>
The Silverlight Panorama control doens't support the behaviour you're after or provide the ability to customize it in a way that will let you do it.
If you really want this then you'll need to build your own control from scratch. I would expect this to be more effort than is justified. Just avoid creating a very wide PanoramaItem instead.
