WPF SubControl (like TextBlock) doesn't inherit Style from window with TemplateSelector

Question

I need help because I don't understand why the controls coming from a datatemplate doesn't inherit the style defined in the window resources. May be is there a workaround? I would be very thankful if someone could give me a solution because I've spent a lots of time to find something. Hereby my exmaple. For instance the Texblock in horrizontal Template is not align: Udapte : I have added background colors. The style is applied to label but not totextblock and textbox defined by the datatemplate. ```

Accepted Answer

I've just tried some simple demos and yes the answer is you cannot apply default Style defined somewhere outside the template to some TextBlock inside the template (including both DataTemplate and ControlTemplate). This does not happen to other controls such as Label, TextBox (although you also said the Style did not apply on the TextBox, but I tried it and actually that's not true).

To fix the issue, the best way is set the Style explicitly for the TextBlock something like this:

```
<TextBlock Text="{Binding Path=SelectedItem.Content ,ElementName=Combo}" 
           TextAlignment="Right" Style="{StaticResource {x:Type TextBlock}}"/>
```

Note that as I said, it's required only for TextBlocks inside template (DataTemplate and ControlTemplate).

The code looks fairly ridiculous but it actually works, without doing that way as you see it won't work.
