The Radzen Blazor Menu uses the Blazor built-in NavLink component so whatever works with the latter will work with the menu. Try adding a slash before all paths to see if makes a difference e.g. "/add/param1"
When either of these two are clicked, the page will not refresh with the new parameter. Is there a way to force this? I know I can use the Click property and force the refresh with UriHelper, but it reloads the application which slows response time. Any help would be appreciated.
