How to change image background for selected item in listBox with buttons in each line ?

I haven't tested it, but you need some code that looks like this:
<ListBox x:Name="lbname" ItemsSource="{Binding myCollection}">
<ListBox.ItemTemplate>
<DataTemplate>
<Button x:Name="btnname" Click="btnname_Click">
<Image>
<Image.Style>
<Style>
<Setter Property="Image.Source"
Value="/myApplication;component/images/buttons/normal.png" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected,
RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}"
Value="True">
<Setter Property="Image.Source"
Value="/myApplication;component/images/buttons/click.png" />
</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
<TextBlock Text="{Binding name}" HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
The idea is to bind directly to the IsSelected
property of the ListBoxItem
object. This is done using a RelativeSource
binding. However, I'm guessing that this code doesn't do what you want... I suggest that you might want to use a ToggleButton
instead... something like this:
<ListBox x:Name="lbname" ItemsSource="{Binding myCollection}">
<ListBox.ItemTemplate>
<DataTemplate>
<ToggleButton x:Name="btnname" Click="btnname_Click" IsChecked="{Binding
IsSelected, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type
ListBoxItem}}}">
<Image>
<Image.Style>
<Style>
<Setter Property="Image.Source"
Value="/myApplication;component/images/buttons/normal.png" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected,
RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}"
Value="True">
<Setter Property="Image.Source"
Value="/myApplication;component/images/buttons/click.png" />
</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
<TextBlock Text="{Binding name}" HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
</ToggleButton>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

if you are using MVVM then make a property in viewModel and bind this to ImageBrush as ImageSource,
when you are selecting value in ListView then get selected record and change image path of this property.
