I'm trying to write a HeaderTemplate
for an extender. So far, I've noticed all the examples use the {Binding}
keyword to get the data from the header. However, what happens if there are multiple controls within the Header? How do I specify that those controls should be inserted at a specific location?
<Window.Resources>
<Style x:Key="ExpanderStyle" TargetType="{x:Type Expander}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<!-- what do I put in here? -->
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Expander Style="{StaticResource ExpanderStyle}">
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock>Some Text</TextBlock>
<TextBlock Text="{Binding SomeBinding}" />
<Button />
</StackPanel>
</Expander.Header>
<Image Source="https://www.google.com/logos/2012/steno12-hp.jpg" />
</Expander>
Should I be moving my binding into the HeaderTemplate
in the style and just overwriting whatever the Header
in the Expander
is?

You can use ContentPresenter
to insert whatever the usual content would be into your Template
For example:
<Style x:Key="ExpanderStyle" TargetType="{x:Type Expander}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<Border BorderBrush="Blue" BorderThickness="2">
<ContentPresenter />
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>

Header's property Content could contain only one object.
If you merge these object in one panel:
<StackPanel>
<TextBlock>Some Text</TextBlock>
<TextBlock Text="{Binding SomeBinding}" />
<Button />
</StackPanel>
then in template you could use {binding}
