I have various checkboxes with Interaction.Triggers and Event Triggers for both Check and Uncheck for each checkbox as shown below. When the checkbox is checked or unchecked I will be catching the CommandParameter value which is different for each checkbox in my ViewModel. I am required to make the Event Triggers as a common code in my XAML which has to work for every different checkbox by catching the CommandParameter value.

I am a novice to C# and WPF. So I am browsing through the dotnet wpf repository on github trying to find how a text selection/highlight made on text in a RichTextBox gets actually rendered onto the screen. So far I found many files, classes and interfaces that are highly interconnected, however I am still unable to exactly figure out where this rendering and its logic is located. Is it a function, an instantiation of an object, passing a message or something else that makes a highlight visible on screen ?

I’m trying to put a page inside of a frame in code, it works fine when I call it from the main function. But when the button press calls it, it does not change the frame’s content. The Frame within the page is already in a page in a frame if that has anything to do with it.

I am repeating my code multiple times in XAML

I want to use an ItemsControl with a ItemsSource. My issue is how to ensure that the items maintain their height ratio when displayed. Each time I resize the window, the items should resize accordingly, but their height ratio should remain constant. I want to display all items without using a scrollbar.
