cannot changing theme settings.

[indigo1715]

I'm using .NET Framework 4.8 and working on WPF.

I defined the handy control as defined in the dictionary, as shown in the code below.

<Application.Resources>
    
    <ResourceDictionary>
        
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>

....

All controls work normally.
I don't know how to change the theme.
I looked for 'ThemeManager' using the preprocessor to define it in the code behind, but it said it was not defined.

Please tell me how to batch change the skins of Handycontrols applied at the code-behind level.

I used GetSkin method to specify Skintype and then changed the resourceDictionary URL.
It worked done. I was using multiple Theme libraries so handycontrol theme change worked by adding the priority library to the last resource.

HandyUI's project was helpful.
