Qun Shen 60

The app uses an custom router component insead of the built-in Router component. When the application runs, it appears that pages not prerendered. Please the see the attached screen shot.

@Hi,@Qun Shen,are you working with .net 8?Could you share your custom router component so that we could reproduce your issue?

Yes. I am using asp.netcore 8. The custom router I am using can be found at https://github.com/oqtane/oqtane.framework/blob/dev/Oqtane.Client/UI/SiteRouter.razor

@Hi,@Qun Shen,I've checked your codes,RenderMode attribute is never used in your custom route attribute,why not just try the codes below in app.razor?

 <div style="@_display">
                <CascadingAuthenticationState>
                    <CascadingValue Value="@PageState">
                        <SiteRouter Runtime="@Runtime" @rendermode="RenderMode" VisitorId="@VisitorId" OnStateChange="@ChangeState" />
                    </CascadingValue>
                </CascadingAuthenticationState>
            </div>

......

@code { 
    
  
 public IComponentRenderMode RenderMode { get; set; } = new InteractiveServerRenderMode(true);  
}

The root component: App.razor alreadly specified render model:InteractiveServerRenderMode

The custom router is inside the Router component

So the rendermodel for the whole site are set!

The website was created using aspnetcore 8 standard blazor templae. and replace the built-in Router component with our custom router.

I also tried,according your suggestion, to set the router render model at custom router level. The result is the same: pages not prerendered!

the source code on the github is .net 7 Blazor Server App and not Blazor Web App. The project I am working on is Net 8 Blazor Web App!

Two projects are same except App.razor and Routers component. New project doest not use any “@page " directive.

It seems that use :@page to define routable componet, pages get prerendered.

But our appliaction is multi-tenant and pages are dynamical and can not use static routing.

Hi,@Qun Shen,Is your question based on this issue?

if yes,try call AddComponentRenderMode method

private RenderFragment BuildRenderFragment(Type componentType)
{
    return builder =>
    {
        builder.AddComponentRenderMode(....);
        builder.OpenComponent(0, componentType);
        builder.CloseComponent();
    };
}

Thanks for you reply. I have experimented according to your suggestion. Unfortunturely my problem strill not solved。

I experimented further and find that if use foramework-provided router, pages get prerrended!

The problem for us is that pages are dynamically generated

and page path can not be predeteriminded!
