I am have made the following usercontrol, and all works well except the 2 Background setter properties with value transparent for both isMouseOver and IsSelected that do nothing..
<UserControl.Resources>
<DataTemplate x:Key="DeviceItemTemplate">
<Border Padding="10,5" Margin="10" BorderThickness="4" BorderBrush="Green" CornerRadius="20" Height="150" Width="150">
<StackPanel Orientation="Vertical">
<TextBox Name="screenNameTextBox"
Margin="10" Height="20"
Text="{Binding Name}" />
<TextBox
Margin="10" Height="20"
Text="{Binding Location}" />
</StackPanel>
</Border>
</DataTemplate>
<DataTemplate x:Key="DeviceItemTemplateSelected">
<Border Padding="10,5" Margin="10" BorderThickness="4" BorderBrush="Orange" CornerRadius="20" Height="150" Width="150" >
<StackPanel Orientation="Vertical" >
<TextBox Name="screenNameTextBox"
Margin="10" Height="20"
Text="{Binding Name}" />
<TextBox
Margin="10" Height="20"
Text="{Binding Location}" />
</StackPanel>
</Border>
</DataTemplate>
<Style TargetType="{x:Type ListBoxItem}" x:Key="DeviceContainerStyle">
<Setter Property="ContentTemplate" Value="{DynamicResource DeviceItemTemplate}"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True" >
<Setter Property="BorderThickness" Value="0" />
<Setter Property="Background" Value="Transparent" />
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="ContentTemplate" Value="{DynamicResource DeviceItemTemplateSelected}"/>
<Setter Property="BorderThickness" Value="0" />
<Setter Property="Background" Value="Transparent" />
</Trigger>
</Style.Triggers>
</Style>
</UserControl.Resources>
<Border
Grid.Column="0"
Margin="10"
BorderBrush="Silver"
BorderThickness="1">
<ListBox ItemsSource="{Binding Devices, UpdateSourceTrigger=PropertyChanged}"
SelectedItem="{Binding SelectedScreen, Mode=TwoWay}"
ItemContainerStyle="{StaticResource DeviceContainerStyle}"
ScrollViewer.HorizontalScrollBarVisibility="Disabled" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
</Border>
This is how it looks
I also tried white, but got same results. I cannot get rid of this blue background.
What am I overlooking please?
-----After receiving mm8 answer-----
Placed all his code in a resource dictionary, made some changes to the solidcolorbrush and BorderThickness, and modified the style section from previous to:
<Style BasedOn="{StaticResource ListBoxItemSSDS}" TargetType="{x:Type ListBoxItem}" x:Key="DeviceContainerStyle">
<Setter Property="ContentTemplate" Value="{DynamicResource DeviceItemTemplate}"/>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="ContentTemplate" Value="{DynamicResource DeviceItemTemplateSelected}"/>
</Trigger>
</Style.Triggers>
</Style>
You need to define a custom ControlTemplate
for the ListBoxItem
to be able to the background of it when the IsMouseOver
and IsSelected
properties are set.
You can right-click on a ListBoxItem
in design mode in Visual Studio or in Blend and choose Edit Template->Edit a Copy to copy the default template into your XAML markup and then edit it as per your requirements.
Here is what it looks like and the resources that are involved:
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<SolidColorBrush x:Key="Item.MouseOver.Background" Color="#1F26A0DA"/>
<SolidColorBrush x:Key="Item.MouseOver.Border" Color="#a826A0Da"/>
<SolidColorBrush x:Key="Item.SelectedInactive.Background" Color="#3DDADADA"/>
<SolidColorBrush x:Key="Item.SelectedInactive.Border" Color="#FFDADADA"/>
<SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>
<SolidColorBrush x:Key="Item.SelectedActive.Border" Color="#FF26A0DA"/>
<Style x:Key="ListBoxItemStyle1" TargetType="{x:Type ListBoxItem}">
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="Padding" Value="4,1"/>
<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="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<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}"/>
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsMouseOver" Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="Background" TargetName="Bd" Value="{StaticResource Item.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="Bd" Value="{StaticResource Item.MouseOver.Border}"/>
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="Selector.IsSelectionActive" Value="False"/>
<Condition Property="IsSelected" Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="Background" TargetName="Bd" Value="{StaticResource Item.SelectedInactive.Background}"/>
<Setter Property="BorderBrush" TargetName="Bd" Value="{StaticResource Item.SelectedInactive.Border}"/>
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="Selector.IsSelectionActive" Value="True"/>
<Condition Property="IsSelected" Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="Background" TargetName="Bd" Value="{StaticResource Item.SelectedActive.Background}"/>
<Setter Property="BorderBrush" TargetName="Bd" Value="{StaticResource Item.SelectedActive.Border}"/>
</MultiTrigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="TextElement.Foreground" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You may for example change the Co lor of
the Item.MouseOver.Background
and Item.SelectedActive.Background
resources.
