In a WPF application I defined default control styles in separate resource dictionaries (e.g. "ButtonStyle.
xaml"), and added them as merged dictionaries to a resource dictionary named "ResDictionary.
xaml".
If I refer this "ResDictionary.
xaml" as merged dictionary in my App.
xaml, the default styles are not applied. However, if I refer the "ButtonStyle.
xaml", it works correctly.
If I recompile the same code in .NET 3.5 or 3.0, it recognizes and applies the default styles referred in "App.
xaml" through "ResDictionary.
xaml", but not in .NET 4.0.
At runtime if I check the Application.Current.Resources dictionary, the default styles are there, but they are not applied, only if I specify the Style property explicitly in the Button control.
Are there any solutions to refer a resource dictionary (containig default styles) this way in .NET 4.0?
App.xaml:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/ResDictionary.
xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
ResDictionary.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Default/ButtonStyle.
xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
ButtonStyle.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="Button">
<Setter Property="Background" Value="Yellow"/>
</Style>
</ResourceDictionary>
