Could you please add some more information? What is the error you're seeing? Did this show up when you added something new to your Grid? Did you discover anything else that influences this behavior? What were you doing when this showed up? Does this only happen on Windows or also Android or iOS?

Thanks

감사

Nice to meet you. Arrange the labels in the Grid cells so that they overlap. Specify one Padding value as a positive number and one as a negative number. When I run it with VS, the build works fine, but an error occurs. It only occurs on Windows OS. thank you.

In my opinion, MAUI layout libraries should not throw exceptions, my philosophy is, if number crunching generates a result that doesn't meet the expectation, just simply return default (what's default is for specification)

@dsuny are you new to MAUI? I am a fan of MAUI.Blazor

do you want to be friends and help each other? do you have a Telegram app link. I am studying how to program while making my own libraries as a hobby

Nice to meet you. I am also a Maui+Blazor developer. The links below are the libraries under development. https://github.com/MetaFrm
