@RenderSection Equivalent in Blazor?

由 一笑奈何 提交于 2019-12-11 07:34:36
问题 Razor pages have a mechanism where you can reference named sections in your layout, and then specify them in your pages that use that layout. For example, if your Layout (_Layout.cshtml) looks like this: @using... ... <!DOCTYPE html> ... <body> ... @RenderSection("modals", required: false) ... and then in your dashboard page, for example, you'd have: <div> ... </div> ... ... @section modals { <div class="modal-container>...</div> <div class="modal-container>...</div> } that would inject the

Can you use a ViewComponent in a Blazor layout

由 我只是一个虾纸丫 提交于 2019-12-11 04:53:33
问题 Just trying Blazor for the first time. With the default blazor template, I added a ViewComponent call to the MainLayout.cshtml: @await Component.InvokeAsync("HeaderComponent") Intellisense shows await can only be used in an async method. I tried the same in a Blazor view - same result. I use the component in an MVC app in the layout (i use vc:header-component there). So I'm not sure if this is possible, or just a current Blazor or VS2019 limitation. 回答1: No, you can't use ViewComponent in

JSInterop.Json.Deserialize is losing milliseconds from DateTime objects

由 醉酒当歌 提交于 2019-12-11 03:42:57
问题 In my Blazor 0.9.0 project I have a large json string for a list of objects with DateTime property including milliseconds. This is passed to my .cshtml file via Ajax and I call Microsoft.JSInterop.Json.Deserialize on the string. This deserializes well except the DateTime objects lose their milliseconds. For JsonConvert this can be rectified by using JsonSerializerSettings DateParseHandling. How do we do this in Blazor? var json = "{\"timestamp\":\"2019-03-01T12:22:26.102Z\"}"; I expect this

What's the difference between ASP.NET Core Hosted and Server-Side Blazor, really?

由 一世执手 提交于 2019-12-11 02:22:15
问题 I'm still struggling to understand the difference between ASP.NET Core Hosted and Server-side Blazor. I know same question already exists, but it's not satisfying. In fact, I couldn't find the satisfying answer anywhere - the answers were more or less the same. If hosted option uses server (IIS, Kestrel), then why server-side ? Confusing... It's a shame that official documentation didn't shed the light either... UPDATE The confusion stems from the fact that we have THREE options to create
