How can i make a dependency property with type List<control> element in UWP-CodePudding

I am new to UWP and C# so i hope that somebody can help me. I am currently trying to make a custom control in UWP but got a problem. My idea is a button to change the theme of the application. For that i want to let the user of my custom control speicify which elements he want the background to change in the XAML-file.

It should look like this (Pseudocode):

<Grid x:Name="Grid1" Grid.Column="1" Background="Black">
   <Button x:Name="Button1"/>
   <local:ModeSelector Grid.Row="1">
      <local:ModeSelector.Tools>
         <Button1/>
         <Grid1/>
         ... 
      </local:ModeSelector.Tools>

   </local:ModeSelector>
</Grid>

My DependencyObject looks like this:

public List<Control> Tools
        {
            get { return (List<Control>)GetValue(ToolsProperty); }
            set { SetValue(ToolsProperty, new List<Control>()); }
        }

        public static readonly DependencyProperty ToolsProperty =
            DependencyProperty.Register("Tools", typeof(List<Control>), typeof(ModeSelector), new PropertyMetadata(new List<Control>()));

in my c# file i then have a list of controls from which i can change the backgroundcolor. In this example it is "Button1", "Grid1", ... . My question now how can i implement this list in my XAML file?

Thank you in advance

I'm not an expert on this, but it sounds like what you're trying to do is apply customized themes.

I would give this article a read through: Custom Themes in UWP Application

And this video here: XAML Themes

I'd suggest you use a list of string instead of a list of Control. I've tested the Control type of list with binding, the databinding will throw exceptions even when you set the x:DataType as Control. So you might need use the name of each control instead if you want to use binding to list all the Controls. Then when you select a control, you could find the control via its name.
