I'm developing a Windows Phone app.
I have the following XAML code:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="GameList" Margin="12" Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10,10,10,5" Height="67" HorizontalAlignment="Center" VerticalAlignment="Center" >
<TextBlock Text="{Binding Name}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
But I couldn't set textblock centered (vertically and horizontally).
There are two ways to achieve this.
The first solution is to specify the ListBox's ItemContainerStyle inside the ListBox and set the HorizontalContentAlignment property to Center.
<ListBox ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Collection}">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Center"/>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
The second solution is to define a style, and apply the style to the ListBox (so it's reusable).
<Style x:Key="ListBoxCenteredItemStyle" TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Center"/>
</Style>
<ListBox
ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Collection}"
ItemContainerStyle="{StaticResource ListBoxCenteredItemStyle}"/>
The ItemTemplate of a ListBox is just a DataTemplate for displaying each data item. If there is a need to style a single row, the ItemContainerStyle is the guy. :)

I want the foregroud color of Placeholder is Foreground="#ffae19". But i get it in black color.
Can any one have solution for this :-)
<ComboBox x:Name="selectLanguage" Background="#5d198e" Foreground="#ffae19" PlaceholderText=" SELECT LANGUAGE" Width="280" Height="40" HorizontalAlignment="Center" VerticalAlignment="Center" DropDownOpened="selectLanguage_Click">
<ComboBox.ItemTemplate>
<DataTemplate>
<Grid Background="#5d198e" Width="280" Height="40">
<TextBlock Foreground="#ffae19" HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding languageName}" ></TextBlock>
</Grid>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
You can override these default resource keys to set the color of the placeholder text without retemplating the control:
<StaticResource x:Key="ComboBoxPlaceHolderForeground" ResourceKey="SystemControlPageTextBaseHighBrush" />
<StaticResource x:Key="ComboBoxPlaceHolderForegroundFocusedPressed" ResourceKey="SystemControlHighlightAltBaseHighBrush" />
You have to edit the default styles of he combobox. Use blend for that, right click on the combobox->edit style. you will get the default style. Look out for placeholder style, and change it accordingly.
Obviously ItemContainerStyle doesn't exist in a Grid, which is the problem.
My program has a ListView that displays a bunch of projects. I want to add a button to each project that gives more info, and that much I can do easily. The problem I'm encountering is the border that appears on each project, which is toggled on/off by clicking the project to show the user which are currently selected. I don't want this border to encircle my button; I want the button placed to the right of the bit with the border.
I can't put the button on a separate list or I'll get two different scroll-able lists, so it must stay within the ListView, but any border on the ListView will encircle everything in the ListView. My solution was to make a StackPanel with two Grids inside the ListView, where the first Grid has all of my old stuff and the toggle-able border and the second grid only has my button. So now I just need to move that border onto the Grid... but how?
XAML code:
<!-- Other code up above... -->
<ListView x:Name="lstAvailableProjects"
Grid.Row="1"
ItemsSource="{Binding ProjectList, Mode=TwoWay}"
Height="Auto"
Width="Auto"
SelectionMode="Multiple"
IsRightTapEnabled="True"
IsDoubleTapEnabled="False"
IsSwipeEnabled="False"
SelectionChanged="lstAvailableProjects_SelectionChanged"
Background="Transparent"
VerticalAlignment="Top"
ItemContainerStyle="{StaticResource ActiveProjectListViewStyle}"
BorderThickness="30,0,0,0">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Grid HorizontalAlignment="Stretch" Width="250" Background="{Binding Converter={StaticResource projectStateColorConverter}}">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="{Binding ProjectName}"
Foreground="Black"
Margin="10 5 0 0"
FontSize="17"
VerticalAlignment="Center"
Grid.Row="0"
HorizontalAlignment="Stretch"/>
<TextBlock Text="{Binding AssignmentRole}"
Visibility="{Binding ProjectAssignmentRole, Mode=OneWay, Converter={StaticResource visibilityConverter}}"
Foreground="Black"
Margin="10 3 0 5"
FontSize="14"
Grid.Row="1"
HorizontalAlignment="Stretch"/>
<TextBlock Text="{Binding StatusText}"
Foreground="Red"
Margin="10 3 0 5"
Grid.Row="2"
FontSize="14"/>
</Grid>
<Grid>
<Button>
<Button.Template>
<ControlTemplate>
<Image Source="../Assets/setting_icon.png" Height="40" />
</ControlTemplate>
</Button.Template>
</Button>
</Grid>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Since the grid items are wrapped You cannot make changes in xaml to achieve it other than overriding the preparecontainerforitemoverride.
A little tricky hack would be to apply transform to the button.
<Button.RenderTransform>
<CompositeTransform TranslateX="100" TranslateY="100"/>
<Button.RenderTransform>
I have some problem: need to make animation that starts from element inside viewbox and finishes outside viewbox
It means:
I have page where elements are placed. There is text block on the top of it and viewbox. I place gridview into this viewbox. And one moment it should start animation from gridview item
<Viewbox HorizontalAlignment="Left" Stretch="Uniform" VerticalAlignment="Top" x:Name="vbChallengeView" >
<Grid x:Name="gdChallenges">
<GridView
Margin="92,64,68,0"
x:Name="GvChallenges"
ItemsSource="{Binding Source={StaticResource GroupedItemsViewSource}}"
VerticalAlignment="Top"
HorizontalAlignment="Left"
ItemTemplate="{StaticResource ChallengeTileTemplate}"
ItemClick="GvPack_OnItemClick"
IsItemClickEnabled="True"
IsZoomedInView="False"
SelectionMode="None"
>
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="IsTabStop" Value="False" />
<Setter Property="Margin" Value="0,0,24,24" />
</Style>
</GridView.ItemContainerStyle>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid MaximumRowsOrColumns="5" Orientation="Horizontal" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
</Grid>
</Viewbox>
How can I determine item size in view box and it's position relatively current window?
Thanks for any ideas
I am developing a Windows store app. At a high level, the page has a Grid with two rows. Along with other controls, the ComboBox is placed in the first row.
The second row has a GridView and the red tile is one of the items in the GridView. The ComboBox is used to display hierarchical data as shown here.
ComboBox
I am working on replacing the ComboBox with a TreeView from WinRT XAML Toolkit as shown here.
TreeView
What I like about the Combobox is that when its open, the opened list sits on top of the GridView. For the Treeview, when I open the parent node, the opened list stays within the specified height along with the scrollbar.
I would like the TreeView to act like the ComboBox so that when opened, it extends out and the opened list sits on top of the GridView. Any idea how I can accomplish that?
Thanks for your help.
Set something like this on the TreeView (adjust max dimensions for available space)
VerticalAlignment="Top"
HorizontalAlignment="Left"
MaxHeight="500"
MaxWidth="500"
Canvas.ZIndex="1"
This will make the ScrollViewer and the TreeView change the size depending on the size of expanded tree up to a max size where it will start scrolling. The ZIndex will make it render on top of items with lower or default ZIndex value at the same level in the visual tree.
You could also put it in a Popup when your root node expands and back out of the Popup when the Popup closes or when the node collapses.
*EDIT
Based on your code - I can see you have a bit of a mess of a lot of nested panels, but with a simple hack you can make it work even with your layout. There are three things to do:
Make the TreeView top-aligned as I mentioned earlier.
The height of the panel the TreeView is inside of is a bit limited (to 20% of page height) by the size of the Grid row it's in. You can add a bit more space by setting a large enough negative bottom Margin value for the TreeView.
Since the TreeView is in the first row of the grid - the second row naturally overlays it when the TreeView extends into the negative margin. You can fix that by setting Canvas.ZIndex="1" on the StackPanel that is the root of your first row or reordering your row elements to reverse the ZIndex.

I've also noticed you are targeting Windows 8.1 at least with your test app, but you are using an old Windows 8.0 version (1.6.1.3) of the toolkit. You can get the latest version (1.8.1 as of 2015-02-01) here: http://www.nuget.org/packages/winrtxamltoolkit.windows
I need to change the StackPanel background color for the item selected by user.

Override/add <SolidColorBrush x:Key="ListViewItemSelectedBackgroundThemeBrush" Color="#YourColor" /> to your Application.Resources. You'll find all default colours in the generic.xaml file here: C:\Program Files (x86)\Windows Kits\8.1\Include\winrt\xaml\design (Assuming you work with x64).
