Change Fill property of Path control inside ListBox - wpf

I have a small question, I've created a ListBox that only contains 2 items. Each item is a Path control that has a Fill attribute set to Black.
Now, what I'm trying to do is, change the colour of this Fill attribute when you select one of the items in the listbox... I would think this should be done with a Style. But when doing so, the style contains a ContentPresenter that maps to the Path and this ContentPresenter has no Fill attribute to change through the IsSelected trigger!
So in other words, how can I still use a Style that maps the Fill attribute?

I recommend you using MVVM pattern with MVVM Light Toolkit. Then you should create Collection of data that you want to dispaly on the list. In your case it can be Data and Fill (Color). Then you need to handled Click event and that's all. I have code that provides such feature, so If you want it, please ask.
But in your case (without MVVM Light toolkit) I would rather do sth like this:
<Style x:Key="Path" TargetType="{x:Type Path}">
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource, AncestorType={x:Type ListBoxItem}}, Path=IsSelected" Value="True">
<Setter Property="Fill" Value="YouColor"/>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource, AncestorType={x:Type ListBoxItem}}, Path=IsSelected" Value="False">
<Setter Property="Fill" Value="YouAnotherColor"/>
</DataTrigger>
</Style.Triggers>
</Style>
Best regards.

Ok... found the answer myself!
When changing the Fill value inside the Path control to a binding one, all works as expected!
Fill="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}}"

Show ContextMenu on whole TreeViewItem line in WPF

I have a TreeView with heterogeneuos node types. Each node type is configuered in XAML using a HierarchicalDataTemplate.
Some of the nodes have a ContextMenu, which is dependent on the type of the node. The ContextMenus are defined as static resources in XAML and attached to a DockPanel in the HierarchicalDataTemplate.
In addition, I am using the ControlTemplate for a TreeViewItem described by bendewey in the following StackOverflow question https://stackoverflow.com/a/672123/1626109. This ControlTemplate is defined so that the complete TreeViewItem is highlighted when it is selected.
A left click on any part of the line, selects the item.
In contrast, the context menus, which are defined in the HierarchicalDataTemplate, only work on the right hand part of the line.
I am looking for a way to configure the ContextMenus so that they are also available on the complete line.
This seems to require attaching the context menu to an element in the ControlTemplate, with a TemplateBinding to something defined in the HierarchicalDataTemplate, but I can't figure out how to do it.
By the way, the solution explorer in Visual Studio has exactly this behavior. The context menu is dependent on the node type, and it is available on the complete item, including to the left of the expand/collapse button.
(Edited) You need to get rid of the two columns of the Grid in TreeViewItem Style:

However, this will distort the Header-Items arrangements. Therefore, you need to adjust the Margin in the HierarchicalDataTemplate part:
<TreeView Margin="50" HorizontalContentAlignment="Stretch" DataContext="{Binding}" ItemsSource="{Binding Models}">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:Model}" ItemsSource="{Binding Models}">
<Border Background="Transparent">
<TextBlock Margin="{Binding Converter={StaticResource lengthConverter}, ConverterParameter=1,
RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=TreeViewItem}}"
Text="{Binding Name}" />
<Border.ContextMenu>
<ContextMenu>
<MenuItem Header="dddd"/>
</ContextMenu>
</Border.ContextMenu>
</Border>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
Note that you should adjusted the converter to take the required extra margin into account:
public class LeftMarginMultiplierConverter : IValueConverter
{
public double Length { get; set; }
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var item = value as TreeViewItem;
if (item == null)
return new Thickness(0);
int extra = int.Parse(parameter.ToString());
var t = item.GetDepth();
return new Thickness(Length * (item.GetDepth() + extra), 0, 0, 0);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new System.NotImplementedException();
}
}
If converter parameter is 1, it will add one point to the depth of the item. I use it for the Header part.
Another approach might be to add a DataTemplate to the ContentPresenter of the TreeViewItem Style. While I don't know how you can bind the ContextMenu, I prefer this one.

Make listboxitem unselectable

I'm writing an small key application and I'm using a listbox to dynamically visualise a list from code. Now the issue is it needs to be used on windows 7 and I'm having multiple issues with the visualisation on that platform.
The code I have is:
<ListBox x:Name="listBoxSecrets" Margin="0,84,10,10" Background="{x:Null}"
HorizontalContentAlignment="Stretch" BorderBrush="{x:Null}" >
<ListBox.ItemTemplate>
<DataTemplate>
<!--<Border BorderBrush="#FFF3560D" CornerRadius="3" BorderThickness="3" Margin="0,0,0,10">-->
<Border BorderBrush="White" CornerRadius="10" BorderThickness="10" Margin="0,0,0,10">
<Grid Background="White">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="30" />
<ColumnDefinition Width="30" />
</Grid.ColumnDefinitions>

<Button ... Grid.Row="0" Grid.Column="2">

</Button>
<Button ... Grid.Row="0" Grid.Column="3" >

</Grid>
</Border>

I tried the following style to no effect:
<Window.Resources>
<Style x:Key="{x:Type ListBox}" TargetType="{x:Type ListBox}">
<Setter Property="Focusable" Value="False" />
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
</Window.Resources>
This is how the selection looks - I don't want it to be selectable. (I have the same issue with the buttons btw - same solution would be applicable?)

After click:
Also: Bonus points if you can help me figure out how to remove the "aliasing" line between the grid and the border around it.. ;-; Only happens on the win 7 mahcine, not my win 8 machine.
I guess you want to remove the selection state of ListBoxItem, if thats right, Please use the below style,
in this i have commented out the triggers responsible for selection and mouse over state.
You can assign this style in ItemContainerStyle of ListBox,,

Why don't you remove the selection upon happening? Like this:
private void listBoxSecrets_SelectionChanged(object sender, EventArgs e)
{
listBoxSecrets.SelectedIndex = -1;
}
You then setup the listener like this:
<ListBox x:Name="listBoxSecrets" Margin="0,84,10,10" Background="{x:Null}"
HorizontalContentAlignment="Stretch" BorderBrush="{x:Null}" SelectionChanged="listBoxSecrets_SelectionChanged" >

ListViewItem custom control doesn't respond to clicks in certain empty spaces that are still part of the item

I am trying to make a custom control for that inherits from ListView and one that inherits from ListViewItem. The appearance is fine. The problem is that when clicking on the parts of the control shown below, the item does not get selected - you have to click directly on the image. The text had the same problem with its margins (you could not click in the margins), but I added padding to them. I thought that adding the content inside of ContentPresenter.Content would fix the problem, but it didn't.
Also, if I add this style to my resources, rather than in Generic.xaml, and remove the DefaultStyleKeyProperty.OverrideMetadata method in NavigationListViewItem.cs, it does work correctly (not sure what's up there).
The code-behind for the custom controls do not have any addition code added into them. Here is the style in Generic.xaml:
<Style TargetType="{x:Type ui:NavigationListViewItem}">
<Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
<Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ui:NavigationListViewItem}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
<ContentPresenter.Content>
<StackPanel x:Name="itemPanel"
MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListView}}, Path=ActualWidth}"
VerticalAlignment="Center">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="19" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition MinHeight="22" />
</Grid.RowDefinitions>
<ui:ColorableImage Grid.Column="0" Grid.Row="0" Source="arrow-right-white.png" Height="15" Width="15" />
<TextBlock Grid.Column="1" Grid.Row="0"
x:Name="itemText"
FontSize="14"
FontFamily="Segoe UI"
FontWeight="Bold"
TextWrapping="Wrap"
VerticalAlignment="Center"
HorizontalAlignment="Stretch"
Text="Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text "
Padding="3,10,10,10" />
</Grid>
</StackPanel>
</ContentPresenter.Content>
</ContentPresenter>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
<Setter TargetName="itemText" Property="Foreground" Value="Red" />
</Trigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="true"/>
<Condition Property="Selector.IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}}"/>

<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>

</Style>
Your Border background for NavigationListViewItem is set to null by default and that won't react to mouse clicks. You need to initialize it to something, for example Transparent
<Style TargetType="{x:Type ui:NavigationListViewItem}">
<!-- other setters -->
<Setter Property="Foreground" Value="White" />
<Setter Property="Background" Value="Transparent" />
also in your Trigger which changes Background you don't need to specify TargetName. Since you already do TemplateBinding you should be to change Background directly on the item.
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<!-- other setters -->
</Trigger>

DataTemplate, Style, Triggers

I have a <ListBox> with custom <ListBox.ItemTemplate> and <DataTemplate> in it:
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="2" CornerRadius="5">
<Image Source="{Binding Picture}" />
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Now when I'm choosing the ListBoxItem it gets ugly with blue colored row selection. I'd like to change it. I want to color only border's background and nothing else. Also I want to change MouseOver behavior. I've tried trough triggers, but ContentPresenter doesn't have Background property.
UPD:
Well, I've managed to change the background on MouseEnter and MouseLeave:
<EventTrigger RoutedEvent="Border.MouseEnter">
<BeginStoryboard>
<Storyboard >
<ColorAnimation Storyboard.TargetProperty="Background.Color"
To="LightBlue" Duration="0:0:0.03"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
But still can't change the Background when item's selected. I'm trying through:
<Trigger Property="ListBoxItem.IsSelected" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
Doesn't work
The coloring you're looking for is in two Triggers inside the template for ListBoxItem, not the ItemTemplate. To change this you need to edit the ItemContainerStyle for the ListBox. This is the default that can be used as a starting point:
<ListBox>
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="HorizontalContentAlignment" Value="{Binding Path=HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="VerticalContentAlignment" Value="{Binding Path=VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="Padding" Value="2,0,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
</Trigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="true"/>
<Condition Property="Selector.IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
</MultiTrigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
You can do this by using triggers. I have in one of my projects something like this:
<Trigger Property="IsSelected" Value="true">
<Setter Property="Panel.ZIndex" Value="1"/>
<Setter Property="Background" TargetName="Bd" Value="{StaticResource TabItemSelectedBackground}"/>
</Trigger>
Though it doesn't change Border color, it shows how to change the Background. So, maybe try to set this to null. This triggers are part of a custom Style in which a tracking is achieved using IsMouseOver property.

WPF Xaml Custom Styling Selected Item Style in a ListBox

I have a ListBox that scrolls images horizontally.
I have the following XAML I used blend to create it. It originally had a x:Key on the Style TaregetType line, MSDN said to remove it, as I was getting errors on that. Now I'm getting this error:
Error 3 Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.
I don't understand how to apply all of this junk that way, I've tried several things, nothing is working.
My goal is to have the selected item's background be white, not blue. Seems like a lot of work for something so small!
Thanks.
<ListBox ItemsSource="{Binding Source={StaticResource WPFApparelCollection}}"
Grid.Row="1" Margin="2,26,2,104" ScrollViewer.VerticalScrollBarVisibility="Hidden"
ScrollViewer.HorizontalScrollBarVisibility="Hidden" SelectionMode="Single"
x:Name="list1" MouseLeave="List1_MouseLeave" MouseMove="List1_MouseMove" Style="{DynamicResource ListBoxStyle1}" >

</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Image}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Wrap the Style Tag with an ItemContainerStyle as below:
<ListBox ItemsSource="{Binding Source={StaticResource WPFApparelCollection}}"
Grid.Row="1" Margin="2,26,2,104"
ScrollViewer.VerticalScrollBarVisibility="Hidden"
ScrollViewer.HorizontalScrollBarVisibility="Hidden"
SelectionMode="Single"
x:Name="list1" MouseLeave="List1_MouseLeave" MouseMove="List1_MouseMove"
Style="{DynamicResource ListBoxStyle1}" >
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent"/>
</Style>
<!-- the rest of your code, but close the ItemContainerStyle -->
</ListBox.ItemContainerStyle>
</ListBox>
I tried the above solution but it didnt worked as expected so I found another way to solve my problem which is to disable selection for listbox
this is what I did
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Focusable" Value="False"/>
</Style>
</ListBox.ItemContainerStyle>
