Adding Properties and Events in Layout @Body

[tsmccartan]

In the default Blazor App, is it possible to hide/show Menu Items in the NavMenu.razor (

) from a Button Click in the Index.razor file?

I don't know how to control the razor file that is loaded into the @Body area by default? I believe it has to do with the @route "/". I have data being loaded there with a selection list of items. And based on what the user chooses, I want to show/hide navigation items in the NavMenu.

Is this possible?
How do you determine the default razor page that is loaded in the @Body area of the layout?
If I add a component in the Layout you can add Parameters, etc. <Components "@MyParam"> /> but I don't know if this is possible with the default index.razor that is being loaded by default in the @Body?

Thanks,
Tom

Thanks for contacting us, @tsmccartan.
You can achieve this using either a service registered in DI and passed to different pages, or using CascadingParameter-s.
Also we're trying to address and simplify this as part of the work we're tracking at #10131
