ASP.Net Core Blazor: How to load different _Host.cshtml files based on header value

由 不想你离开。 提交于 2020-05-13 19:24:08
问题 I would like to load a _Host.cshtml file in an ASP.NET Core Blazor project (Server side Blazor) based on a header in the request. For example: A client connects to example.com and is redirected to a _Host.cshtml file specific for tenant A. Another client connects to test.com and is redirected to a _Host.cshtml file specific for tenant B. The _Host.cshtml file looks somehow like this: @page @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers <!DOCTYPE html> <html lang="en" dir="ltr"> <head>

问题 I am trying to change change a string, being used for a title, in my blazor-server-side application. But I am having trouble getting the UI to update. I tried using StateHasChanged(), but that didn't work so I looked around and found that on the FlightFinder Demo that was made, it has an OnChange event Action, so I am trying to implement that.

问题 I created a new ASP.NET Core 3.0 Web application and selected the Model-View-Controller option. I wanted to add Blazor Server side, so I added the below to the Startup.cs file. services.AddServerSideBlazor(); endpoints.MapBlazorHub(); and added the script file <script src="_framework/blazor.server.js"></script> in my Layout file. I created a simple component that displays what I enter in a textbox, and added the component to my Index.cshtml view. It works within Visual Studio, but when I push

Blazor EditContext doesn't trigger FieldState

由 心已入冬 提交于 2020-05-12 07:18:19
问题 When values change in the Form Component. The Editform does not validate and it does not set the IsModified of the FieldState to true. Only on submit it will validate. I see when the values change, the class "Modified" is not added the input tag in HTML. So it looks like the EditContext is not setting the FieldState? How can I achieve that? Many thanks! Code (Simplified): Form Component @typeparam TItem <EditForm EditContext="_editContext" OnValidSubmit="OnValidSumit">
