WinUI3 : Which is the best way to store an identifier in winui control

Question

Hi,

Im working on the WinUI3 desktop application in c++ without using XAML. I want to store an identifier in winui3 control, and I learned that we could do it with the help of Name property or Tag property.

My identifier is an integer, to store it in the Name property, I will have to convert it to hstring, and to keep it in the tag property I have to box it to inspectible, and to get back the identifier I have to unbox it.

So which is the best way to stare an integer identifier? does boxing and unboxing the value have a significant overhead?

Thank you

Hello,

Welcome to Microsoft Q&A!

I more recommend you use the Name property.

And according to the Doc: Boxing and Unboxing

It is best to avoid using value types in situations where they must be boxed a high number of times. Boxing and unboxing are computationally expensive processes.

Boxing and unboxing the value will have a significant overhead.

Thank you.
