[Solved] Implicit Styles - Basing styles on theme style

[Jens]

Hey,

i just switched from StyleManager to implicit styles using this guide:
http://docs.telerik.com/devtools/silverlight/styling-and-appearance/styling-apperance-implicit-styles-overview

Using the styles from the theme dll provided in the NoXaml folder works fine.

1.<ResourceDictionary>
2.    <ResourceDictionary.MergedDictionaries>
3.        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/>
4.        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/>
5.        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
6.        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Docking.xaml"/>
7.    </ResourceDictionary.MergedDictionaries>
8.</ResourceDictionary>

But when trying to create a style based on an existing one

1.<Style x:Name="MyComboBox" TargetType="telerik:RadComboBox" BasedOn="{StaticResource RadComboBoxStyle}">
2.
3.</Style>

The RadComboBoxStyle (or any other base style) cannot be found. When referencing the .xaml files from the Themes.Implicit folder everything works as expected 

1.<ResourceDictionary Source="Resources/Themes/Windows8/System.Windows.xaml"/>
2.<ResourceDictionary Source="Resources/Themes/Windows8/Telerik.Windows.Controls.xaml"/>
3.<ResourceDictionary Source="Resources/Themes/Windows8/Telerik.Windows.Controls.Docking.xaml"/>
4.<...>

Im just curious if this is the way things work. Without custom styles, use the .dll - if your want custom styles use the xaml files. But i dont see why referencing the .dll makes any difference. Can you explain this behaviour to me?

 Thanks & Cheers,

Jes

Hello Jens,

There is no such limitations. It appears that the problem is related to the structure of your application's resources. Can you please provide us with more information or a sample project that can shed some light on this so we can be able to help you further?

It's a Silverlight 5 application and that's my whole App.xaml

59.        </ResourceDictionary>
60.    </Application.Resources>
61.</Application>

All .xaml files are set to Build Action - Resource.

Thanks for having a look!

Hello again,

In order to make this work, you need to merge the needed telerik resource dictionary in Styles.xaml.

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</ResourceDictionary.MergedDictionaries>

You can check the attached project. Please also note that the order of merging the resource dictionaries in App.xaml is important. You can follow our recommendations described in our help.
