I am trying to establish the color of my font and the highlighted color. With the font color I do not know how and the highlighted does not seem to work. It is already a list binded to the comboBox.
<ComboBox x:Name="selectCurrentLUT" HorizontalAlignment="Left"
Height="21" Margin="2,0,0,0" VerticalAlignment="Top"
Width="121" FontSize="15" FontFamily="Microsoft Sans Serif"
ItemsSource="{Binding AllLUTLibraries}">
<ComboBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.WindowBrushKey}" Color="#404040"/>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Yellow" />
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Yellow" />
</ComboBox.Resources>
</ComboBox>
Your code is working fine after I copied/pasted it in a new WPF app.
Here is a commented version with each SolidColorBrush you would want to use.
<ComboBox x:Name="selectCurrentLUT" Width="100" Height="50" FontFamily="Microsoft Sans Serif" ItemsSource="{Binding MyList}">
<ComboBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.WindowTextBrushKey}" Color="Red"/> <!-- Font color of all items -->
<SolidColorBrush x:Key="{x:Static SystemColors.WindowBrushKey}" Color="Green"/> <!-- Background color of all items -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Blue"/> <!-- Font color of the highlighted item -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Yellow"/> <!-- Background color of the highlighted item -->
</ComboBox.Resources>
</ComboBox>
Hope it helps.

I'm trying to add a Style to a datagrid, but I'm getting this error:
If I comment the style part everything works fine.
Here is my XAML, can anybody help me? thank you

<Style TargetType="DataGridRow">

</dg:SelfBindingDataGrid>

You have added the Style as data item, but apparently wanted to add it to the Resources of the SelfBindingDataGrid:
<dg:SelfBindingDataGrid ...>
<dg:SelfBindingDataGrid.Resources>
<Style TargetType="DataGridRow">
...
</Style>
</dg:SelfBindingDataGrid.Resources>
...
</dg:SelfBindingDataGrid>
If you intended to set the Style of the SelfBindingDataGrid, it should look like this:
<dg:SelfBindingDataGrid ...>
<dg:SelfBindingDataGrid.Style>
<Style TargetType="dg:SelfBindingDataGrid">
...
</Style>
</dg:SelfBindingDataGrid.Style>
...
</dg:SelfBindingDataGrid>
My ScrollViewer is auto scrolling to a middle offset, even when I try to force it back to a 0 offset it still aligns incorrectly
Here is part of the XAML:
<ScrollViewer x:Name="ScrollView" Grid.Row="0" Grid.Column="0" VerticalScrollBarVisibility="Auto">
<TreeView Grid.ColumnSpan="2" Name="LOBSummaryTree"
BorderThickness="0" DataContext="{Binding}">
<TreeView.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
<common:VisibilityConverter x:Key="VisibilityConverter"/>
<common:TextStyleConverter x:Key="TextStyleConverter"/>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate DataType="ContentPresenter">
<StackPanel x:Name="StackGroups" Orientation="Horizontal">
<TextBlock Name="txtBox" Tag="{Binding}">
And the attempt from the code behind to force the offset:
var scrollViewer = this.ScrollView;
if (scrollViewer != null)
{
scrollViewer.InvalidateScrollInfo();
scrollViewer.ScrollToHorizontalOffset(0);
UpdateLayout();
}
What am I doing incorrectly, I want the alignment of the horizontal scollbar to be forced to the left on the initial load of the treeview?
Imagine I have this brush:
<SolidColorBrush x:Key="MySolidDarkBackground" Color="{DynamicResource DarkBackgroundColorTop}" />
How can I use this brush for a scrollviewer background but with a different opacity?
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="1">
<ScrollViewer.Background>
< ??? >
</ScrollViewer.Background>
</ScrollViewer>
You'd either have to create a second Brush resource and use it:
<SolidColorBrush x:Key="MyTransparentDarkBackground" Opacity="0.5" Color="{DynamicResource DarkBackgroundColorTop}" />
<ScrollViewer Background="{DynamicResource MyTransparentDarkBackground}" />
Or you could just reuse the dynamic Color resource:
<ScrollViewer>
<ScrollViewer.Background>
<SolidColorBrush Opacity="0.5" Color="{DynamicResource DarkBackgroundColorTop}" />
</ScrollViewer.Background>
</ScrollViewer>
I have a ListBox with some ListBoxItems. Each ListBoxItem contains some text and a background image. When the user clicks a ListBoxItem I want to add an image on top of the ListBoxItem (it decorates the item with some additional looks).
I'm looking for a way to overlay the image onto the clicked ListBoxItem. That's the code I have so far:
<ListBox Margin="0,34,0,25.113" Background="{x:Null}" BorderThickness="0">
<ListBoxItem Content="First Item" Height="71.96" Margin="0,10,0,0">
<ListBoxItem.Background>
<ImageBrush ImageSource="Untitled-4.png"/>
</ListBoxItem.Background>
</ListBoxItem>
</ListBox>
Put your ListBoxItem.Content in a panel which allows overlapping controls, such as a Grid, and make your top image's Visibililty be based on ListBoxItem.IsSelected
<ListBox.Resources>
<BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" />
</ListBox.Resources>
<ListBoxItem Height="71.96" Margin="0,10,0,0">
<ListBoxItem.Background>
<ImageBrush ImageSource="Untitled-4.png"/>
</ListBoxItem.Background>
<Grid>
<TextBlock Text="First Item"
VerticalAlignment="Center" HorizontalAlignment="Center" />
<Image Source="SomeImage.jpg"
Visibility="{Binding IsSelected,
RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}},
Converter={StaticResource BooleanToVisibilityConverter}}" />
</Grid>
</ListBoxItem>
Edit
You can also remove the blue background for the SelectedItem by overwritting the HighlightBrush Color and making it Transparent
<ListBox.Resources>
<BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" />
<Style TargetType="{x:Type ListBoxItem}">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
</Style.Resources>
</Style>
</ListBox.Resources>
I would like to apply a style on a WPF Expander Header. In the following XAML I have an Expander but the style is for all of it not just for the header.
Thanks.

I have combined some XAML from Josh Smith and MSDN and came up with a solution. Indeed, the control (al least the header) must be retemplated.

I think Vasile's answer is on the right track, but it seems like it does a lot more than the original poster needed. All the original question was asking to do was to change the background of the header. While the change presented does do that, it also does other things.
One of these other things is to replace the default implementation, I believe a ContentPresenter, with a TextBlock. So what happens when later we change our Expander so that the header is more complicated? Maybe something like:
<Expander>
<Expander.Header>
<StackPanel>
<Border height="5" width="5" Foreground="Blue"/>
<TextBlock>Ha!</TextBlock>
</StackPanel>
</Expander.Header>
</Expander>
I don't know, but it's not good. Instead, I think we want to keep this simple.
<DataTemplate x:Key="expanderHeader">
<ContentPresenter
Content={Binding}
TextBlock.Background={StaticResource myBrush}/>
</DataTemplate>
<Style TargetType="Expander">
<Setter Property="HeaderTemplate" Value="{StaticResource expanderHeader}"/>
</Style>
That way when someone puts something that is not just text in our styled expander, we don't break. If you want to make sure you wrap the entirety of what they do with this background, which is probably desired, that would look like:
<DataTemplate x:Key="expanderHeader">
<Border Background={StaticResource myBrush}>
<ContentPresenter Content={Binding}/>
</Border>
</DataTemplate>
Depends what you want to style -- you can style any part of it. If you want to change the content in the header, just place all your UI in the Expander.Header property, and it'll show in the header area.
if that does't meet your needs, you probably need to re-template the control. Take a look at the control templates shipped in WPF here
