Convert to NoXaml approach creates errors in my styles

[Joe]

I've been using the UI for WPF with the regular binaries and the StyleManager for a while.  Today I took a shot at switching to the NoXaml binaries.   Unfortunately my change has broken all of the custom styles I myself made for Telerik controls.  Specifically, the XAML parser blows up when it see me attempting to base my style on the default one like this:

<Style TargetType="{x:Type tk:RadRadioButton}"
   BasedOn="{StaticResource {x:Type tk:RadRadioButton}}">
    <Setter Property="CornerRadius" Value ="3"/>
</Style>

The "BasedOn" clause causes the problem.  I get the dreaded "Provide Value on StaticResourceHolder" error.  It would appear it cannot locate that default style for RadRadioButton on which I am trying to base my style.

Can you help me figure out further I need to do to make these styles work again?


I tried to follow the instructions here:

https://docs.telerik.com/devtools/WPF/styling-and-appearance/styling-apperance-setting-a-theme-overview

I removed all assembly references from the regular binaries and replaced them with references to the NoXaml equivalents.

Instead of copying the XAML files, I tried the approach that says to reference a theme from the /Binaries/NoXaml folder.

And since I am using the Windows8Touch, I m

https://docs.telerik.com/devtools/WPF/styling-and-appearance/themes-suite/common-styles-appearance-colorizing-metro-theme

And so I did this at the start of my application resources in App.xaml

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <tk:Windows8ResourceDictionary/>
            <tk:Windows8TouchResourceDictionary/>

Am I missing something?

Hi Joe,

Thank you for the code snippet.

Let me first start with that the name of the default style is created using the name of the control followed by a "Style" suffix. So in your case, the name of the default style of the RadRadioButton will be RadRadioButtonStyle. You can take a look at our Styling the Controls help article for further information.

<Style TargetType="{x:Type tk:RadRadioButton}" BasedOn="{StaticResource {x:Type tk:RadRadioButtonStyle}}">
    <Setter Property="CornerRadius" Value ="3"/>
</Style>

You can use this approach for all controls which you are using from our suite. Give it a try and let me know if you were able to run the project successfully.

In my case it was even shorter:

<Style TargetType="{x:Type tk:RadRadioButton}" BasedOn="{StaticResource RadRadioButtonStyle}}">
