Hello Friends. I was wondering if someone has experience using the RelayCommand in a .net Maui application? I need to pass a value that I set in my picker control to a function as a parameter. Thanks for any help.

Can you please provide more details on what exactly you're trying to do and what specifically you're having trouble with?
We can help you better if you provide the versions you're using of VS, MAUI, and your target platforms, the problem you're trying to solve, what you've already tried to solve it, and how that isn't working.
MAUI doesn't provide its own RelayCommand: there are several available in different toolkits you can use with MAUI. I think they all work essentially the same, but there are some small differences.
MAUI Pickers are commanding controls and don't work directly with Commands. You can bind to the SelectedIndex or SelectedItem, you can handle the SelectedIndexChanged event, or you can associate a commanding control such as a button to let the user explicitly fire off the command. How best to deal with this will depend on your specific design and scenario.Some docs to start with:
Maui Fundementals.Data Binding.Commanding in the MAUI docs
.Net Community Toolkit's RelayCommand in the .Net Community toolkit docs -
