How do I use an existing element as content for every new tabview item?

Question

Hi I am using C# WinUI 3 WinAppSDK for my app.
I have a tab view with add tabs option and i also have a home page panel which is collapsed at general state.
Now whenever the user adds a new tab, I want the same home page to appear as its content instead of programmatically adding each element in the tabview item.
When I set this:
newItem.Content = homepagegrid;

I get this error:
System.ArgumentException: 'Value does not fall within the expected range.'

Hello @Hemanth B
Welcome to Microsoft Q&A!

Have you read this document Create a tab view?

I also encountered the same problem when adding a panel to the TabView, you can write the panel into a page and then add this page to the content of the tabview.

Frame frame = new Frame();  
newTab.Content = frame;  
frame.Navigate(typeof(Page1));  

Thank you.
