Hi there I am trying to layout may App in dockpanel.
I have on relatively wider Grid on left and narrow Grid on right. I want the right grid of fixed width but left one to grow as I resize my main window. Here is my XAML:
<Window
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"
x:Class="WebSpark.MainWindow"
x:Name="Window"
Title="MainWindow"
Width="640" Height="480">
<DockPanel x:Name="LayoutRoot" Background="#FF474747" LastChildFill="True">
<Grid DockPanel.Dock="Top" Height="23" Background="#FFEF1212" />
<Grid DockPanel.Dock="Top" Height="23" Background="#FFF7E30D" />
<Grid DockPanel.Dock="Left" Background="#FF0A38F1" MinHeight="396" Width="{Binding ElementName=LayoutRoot,Path=ActualWidth}" MaxWidth="428" />
<Grid DockPanel.Dock="Right" HorizontalAlignment="Right" Width="198" />
</DockPanel>
Here is the behavior. Restored window: http://s17.postimage.org/tk1pov6b3/Restored.png
Maximized window: http://s9.postimage.org/457s5r23j/Maximized.png
As you can see in the maximized window, the blue panel should have stretched, but it is not. What's wrong here? Please help. Thank you.
Take advantage of LastChildFill="True". This code ensures that the grey box has fixed size and the blue one has a variable size.
<DockPanel x:Name="LayoutRoot" Background="#FF474747" LastChildFill="True">
<Grid DockPanel.Dock="Top" Height="23" Background="#FFEF1212" />
<Grid DockPanel.Dock="Top" Height="23" Background="#FFF7E30D" />
<Grid DockPanel.Dock="Right" HorizontalAlignment="Right" Width="198" />
<Grid DockPanel.Dock="Left" Background="#FF0A38F1" MinHeight="396" />
</DockPanel>

I would like to add hover actions to a ListViewItem, but it seems that in the ListViewItem.DataTemplate the "PointerOver" state is not triggered.
I was creating a custom ItemContainerStyle but in this style, I can just set specific properties related to the TargetType 'ListViewItem'. In my case, I would like to have a button which is only visible, when the user hover over the item.
I want to use the VisualStateManager, but maybe I havn´t understood the concept behind styles, templates and user interaction with bindings in between.
Are there good references/documentation for this?
Thank you in advance

For a scoreboard app I'm building the client wants a particular look for the the team name and score:
Since I need to use these in various places in the UI, I figured I'd wrap them as a UserControl. Here's XAML for the image shown above (which has been significantly simplified from the actual):
<UserControl x:Class="Scoreboard.TeamNameAndScoreControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Scoreboard"
mc:Ignorable="d"
d:DesignHeight="30" d:DesignWidth="100">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label
Name="TeamName"
BorderBrush="AliceBlue"
BorderThickness="1"
Content="WEST"
FontSize="20"
Padding="0"
Background="Gray"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
<Label
Name="Score"
BorderBrush="AliceBlue"
BorderThickness="1"
Content="2"
Grid.Column="1"
Padding="0"
Background="White"
FontSize="20"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
</Grid>
</UserControl>
What's important to note, for the purposes of this question, is that the 5-2 proportional sizing of the TeamName and Score labels is critical.
Since some of the various locations within the app's UI that I want to use this control are differently sized, and since I want the control to proportionally respond to window size changes, I figured I'd wrap the Grid in a Viewbox:
<UserControl x:Class="Scoreboard.TeamNameAndScoreControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Scoreboard"
mc:Ignorable="d"
d:DesignHeight="30" d:DesignWidth="100">
<Viewbox>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="WEST"
FontSize="20"
Padding="0"
Background="Gray"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="2"
Grid.Column="1"
Padding="0"
Background="White"
FontSize="20"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
</Grid>
</Viewbox>
</UserControl>
The problem is that when wrapped by the Viewbox, the Grid seems to convert the ColumnDefinition.Width values effectively to "Auto", so that the result looks like this:
I've tried every possible combination of the Viewbox.Stretch and Viewbox.StretchDirection properties which of course significantly change the appearance, but do not "fix" the issue with the Grid's column widths.
Changing the HorizontalContentAlignment of the Labels seems to have no effect.
I have tried setting setting the SharedSizeGroup attribute but no joy:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*" SharedSizeGroup="A"/>
<ColumnDefinition Width="2*" SharedSizeGroup="A"/>
</Grid.ColumnDefinitions>
I've tried restructuring to instead just wrap each Label in a Viewbox, but the Viewboxes don't fill the Grid cells, making it look just weird:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Viewbox>
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="WEST"
FontSize="20"
Padding="0"
Background="Gray"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
</Viewbox>
<Viewbox Grid.Column="1">
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="2"
Padding="0"
Background="White"
FontSize="20"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
</Viewbox>
</Grid>
Please note again that the images and XAML shown here have been significantly simplified for the purposes of this question, and actually include an extensive set of styles to enhance the look of the borders, backgrounds, and fonts of each Label. The point is, the fix will unfortunately not be as simple as setting the background of the Grid (or something like that).
So, any thoughts as to why are my ColumnDefinition.Width values seemingly being changed to Auto and how can I fix it?
I've largely figured it out.
I needed to manually set the Width/Height of the Grid, which forced the Viewbox (which takes its size from its child) to be the same size:
<UserControl x:Class="Scoreboard.TeamNameAndScoreControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Scoreboard"
mc:Ignorable="d"
d:DesignHeight="30" d:DesignWidth="100">
<Viewbox>
<Grid Width="100" Height="30">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="WEST"
FontSize="20"
Padding="0"
Background="Gray"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
<Label
BorderBrush="AliceBlue"
BorderThickness="1"
Content="2"
Grid.Column="1"
Padding="0"
Background="White"
FontSize="20"
FontWeight="Bold"
HorizontalContentAlignment="Center"
/>
</Grid>
</Viewbox>
</UserControl>
Now the Grid is honoring the 5*/2* column widths I'd assigned.
It's now clear (to me) that before I made this change the Grid really had no idea how large to make itself (since when I added the Viewbox the Grid went from having a parent that dictated its size - the UserControl - to a parent that gets its size from its child). So apparently under these circumstances it simply decides to have each cell wrap (take its size from) its children (i.e. "Auto" sizing).
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.
Here's the updated code:
