Declaring more complex Header and Content
If the information in the Header and/or the Content is more complex then we can rely on the XML Element initializing technique. Below is the sample xaml-code:
CopyXAML
<telerik:RadExpander>
<telerik:RadExpander.Header>
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="Header" />
<Rectangle Grid.Column="1"
Height="2"
Margin="5,0,0,0"
VerticalAlignment="Center"
Fill="Gray" />
</Grid>
</telerik:RadExpander.Header>
<StackPanel Orientation="Vertical">
<Ellipse Width="33"
Height="33"
Margin="5"
Fill="Yellow" />
<Ellipse Width="33"
Height="33"
Margin="5"
Fill="Blue" />
<Ellipse Width="33"
Height="33"
Margin="5"
Fill="Red" />
</StackPanel>
</telerik:RadExpander>
