Label and Expander control with rounded corners - wpf

Question

Hi I try make a style with rounded corners for label and expander control.
Label style:
<Style x:Key="InfoLabelStyle" TargetType="{x:Type Label}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Border Name="Border" Background="#BFE3FE" BorderBrush="#BFE3FE" BorderThickness="1" CornerRadius="7" Padding="3">
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="FontSize" Value="12"/>
<Setter Property="FontWeight" Value="Normal"/>
<Setter Property="Height" Value="25"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="#BFE3FE"/>
<Setter Property="Background" Value="#BFE3FE"/>
<Setter Property="Margin" Value="2,4,0,1" />
<Setter Property="Padding" Value="4,0,0,0" />
</Style>
I use multibinding on this style in view:
<Label Style="{StaticResource InfoLabelStyle}">
<Label.Content>
<MultiBinding StringFormat="{}{0}, {1} rokov">
<Binding Path="Oponent.Info.Sex" Converter="{StaticResource sexConverter}"/>
<Binding Path= "Oponent.Info.Age"/>
</MultiBinding>
</Label.Content>
</Label>
But if I run app, content of this label is empty, binding is good, I try it on textBox control and work.
Second problem is, I would like have also rounded corners on expander control.
I try same way as in label style:
<Style x:Key="InfoExpanderStyle" TargetType="{x:Type Expander}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Expander}">
<Border Name="Border" Background="#BFE3FE" BorderBrush="#BFE3FE" BorderThickness="1" CornerRadius="7" Padding="3">
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Applu style on Expander control:
<Expander Name="InfoExapnder"
Header="{Binding Path=Oponent.Info.Nick, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
Style="{StaticResource InfoExpanderStyle}"
IsExpanded="True"
FontSize="18"
FontWeight="Normal"
Background="#ECEBEB"
Margin="3,0,3,0"
Grid.Row="0">
<Grid>
</Grid>
But result is same, empty content of the control.
What I do bad?

The label is empty because you've re-templated it but not specified where the content should be placed. You want something like:
<ControlTemplate TargetType="{x:Type Label}">
<Border Name="Border" Background="#BFE3FE" BorderBrush="#BFE3FE" BorderThickness="1" CornerRadius="7" Padding="3">
<ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
</Border>
</ControlTemplate>
