Trying to propagate CascadingParameters[CP] from Parent to Child. and it's going [explicative deleted].

Basically, got user logging on. Grab UserID and shove into CP. Got value here.

Call child form. declare CP the same way as on parent

[CascadingParameter]
public string LogID{ get; set; }

And it's null. [headdesk]

I've tried putting a name on it

[CascadingParameter(Name='UID")]
public string LogID{ get; set; }

this makes it null coming back from login

I'm probably missing something very simple - but I'm about ready to take a flamethrower to this code.

Can someone 'splain it to me, please?
