If overlapping navigation requests are made, the latest request always cancels earlier requests, which means the following: The app may treat multiple back and forward button selections as a single selection. Sample The following sample demonstrates the use of a RESTful Web API implemented with ASP.NET Core and Entity Framework. Component parameters can only receive query parameter values in routable components with an @page directive. The previous posts have covered aspects of the Blazor WASM app for browsing Sample C# .NET Core Sample apps on the server. The first part of the query string is key, and each key-value is separated by a =. When the Router component navigates to a new page, the FocusOnNavigate component sets the focus to the page's top-level header (

). Pass NavigationOptions to NavigateTo to control the following behaviors: For more information on obtaining the state associated with the target history entry while handling location changes, see the Handle/prevent location changes section. The Router component supports an OnNavigateAsync feature.

A different query parameter name is specified for the {QUERY PARAMETER NAME} placeholder: In the following example with a URL of /search?filter=scifi%20stars&page=3&star=LeVar%20Burton&star=Gary%20Oldman: Use NavigationManager.GetUriWithQueryParameter to add, change, or remove one or more query parameters on the current URL: Call NavigationManager.GetUriWithQueryParameters to create a URI constructed from Uri with multiple parameters added, updated, or removed.
