Question Updating Modal 4.1.0 to 5.0.1

I am trying to update Blazor.Server Blazored.Modal from version 4.1.0 to the new version 5.0.1 and it is beating me up. The 4.1.0 version works perfectly though. If I add your CascadingBlazoredModal component as you request when the application starts it crashes on the <app> line in the _Host.cshtml below with a error of “InvalidOperationException: Blazored.Modal.BlazoredModal requires a cascading parameter of type IModalService”. Is there an issue with having two components wrapping the router in the App.razor file? How do I get around this issue?

The App.razor page already has a “CascadingAuthenticationState” component wrapping the router and has some additional parameters the application needs that are stored in your loacalStorage component.

`@code{ [Parameter] public string UserAgent { get; set; } [Parameter] public string IPAddress { get; set; } [Parameter] public string ServerUrl { get; set; }

protected override async Task OnAfterRenderAsync(bool firstRender)
{
    if (firstRender)
    {
        await localStorage.SetItemAsync("UserAgent", UserAgent);
        await localStorage.SetItemAsync("IPAddress", IPAddress);
        await localStorage.SetItemAsync("ServerUrl", ServerUrl);
    }
}

} ` And then the _Host.cshtml has some code like below inside the body tags:

<app> <component type="typeof(App)" render-mode="ServerPrerendered" param-UserAgent="@Model.UserAgent" param-IPAddress="@Model.IPAddress" param-ServerUrl="@Model.ServerUrl" /> </app>

Might not be related to your problem, but check if you have removed the leftover <BlazoredModal/> from <MainLayout> component.

This fixed it for me.

Hi,

Might not be related to your problem, but check if you have removed the leftover <BlazoredModal/> from <MainLayout> component.

After upgrade to the new version I have added the new <CascadingBlazoredModal/> to App.razor wrapping the router and got tripped by this (App would crash (js interop excepctions), or double Modals would appear).
