.Net MAUI grid tag seems to have some magic associated with it.
Oover the last couple of years, I've been trying my best to learn .net maui. one of the things that i have found is that the <grid /> tag seems to have some magic in it. first, i found that the listview didn't work right without it, thank you to whoever identified that for me. then I was working on an issue I found last with a third party control i decided to try. i had tried a bunch of things with no luck. i saw some example somewhere with a grid control. i put that in, and poof, bob's your uncle and it all worked. i played around with things more and it all seems to be working now.
if you run into an issue with display in maui, try wrapping everything in a grid and see if it works.
good luck!
