QUESTION
I have a .net cor 3.1 Blazor server project. I use the default identity system in this project. I want to access a specific razor page without login. How do I do that? Any Idea?
I tried adding @attribute [AllowAnonymous]
to the razor page. But it did not work for me
_Host.cshtml
...ANSWER
Answered 2022-Mar-13 at 10:32I found an answer. I created another _Host.cshtml with @attribute [AllowAnonymous]
in a separate folder inside of the Pages
folder and I put my razor page in that folder.
Add @layout PublicLayout
to your anonymous access component. In my case, MyAnonymousComponent.razor. PublicLayout
is PublicSection/PublicLayout.razor
My project structure is like this

My problem is: I am unable to pass array data from the view (HTML-select component multiple in mode) to the controller where there is a one-to-many relationship.
I tried to use Microsoft.AspNetCore.Mvc.TagHelpers
for the view.
Please see the MVC design (I simplified it):
Model
...ANSWER
Answered 2022-Mar-12 at 10:12In your select, the option field value is id
, hence you should expect a list of Product.id
.
Follow the steps below;
- Make a view model where we will bind the Name and Id list.

Given an editor for statement in a regular razor view in ASP.NET Core 6.
...ANSWER
Answered 2022-Mar-08 at 02:30Your tag helper will be run based on the content of your [HtmlTargetElement]
attribute.
When your tag helper is run, your properties will be bound based on any [HtmlAttributeName]
. But this binding is optional and will not prevent your tag helper from running.
Since you have only specified [HtmlTargetElement("input"
and haven't included any required Attributes =
, your tag helper will be run against all tags even if they have no
asp-for
attribute. Which explains why you are seeing that your For
property is always null
.
TLDR: what you need is;

...ANSWER
Answered 2022-Feb-21 at 09:25Looking at the issue with fresh eyes, I've realised my mistake - it turns out that it wasn't complaining about appendTo
, but rather panel
. I hadn't realised that was part of another library - importing that library after jquery (but before the custom function) solved the issue.
I'll leave the question here in case someone else goes down the train of thought that I did on Friday.
QUESTION
I have a blazor server application with authentication (single user accounts). The plan was to leave the default EF database handling all the authentication stuff and have a separate SQL database with the application data, which I access via my own data access layer.
The EF database stores email address to the username and displays this as "Hello, abc@xyz.com" if a user is logged in. Since I store the first and last name of the user in my application database, I wanted the text to change to display the first name: "Hello, abc!"
For some reason in a blazor project we have:
- Shared/LoginDisplay.razor
- Pages/Shared/_LoginPartial.cshtml
- Areas/Pages/Shared_LoginPartial.cshtm
In the Shared/LoginDisplay.razor file I managed to display the first name as follows (IUserData coming from my data access lib):

Answered 2022-Feb-15 at 09:11You just need to inject the UserManager class and SignInManager onto whatever page you wanting to access that layer.

QUESTION
I have an ASP.NET web site that access Google Drive using the .NET API v3. I followed the .NET Quickstart to create credentials and generate a token. The redirect_urls
section of the JSON credential file looks like this...
ANSWER
Answered 2021-Dec-20 at 17:43If you are using the code in that quickstart, then it won't work in a web app. The code there is for a desktop app, and uses your browser to open the oAuth screen.
That page really doesn't make this clear, I picked this up from this comment on a GitHub issue. To quote (spelling mistakes included!)...
GoogleWebAuthorizationBroker.AuthorizeAsync is for iinstalled applicatons. Its going to try and open the authorization web browser on the server which is not going to work.
Your going to need something like Web applications (ASP.NET MVC)
However, the code in that link is for MVC, and I don't know if it will work with Blazor, as auth is a whole new ball game there. If you read the previous comment in that GitHub issue, you'll see the suggestion that you perform user auth in a standard ASP.NET Core part of the app, then passing the IGoogleAuthProvider
into Blazor.
Hope that helps, even if it isn't what you wanted to hear!

QUESTION
Is there more elegant way how to mix 2 bootsraps/css together in one project?
I have an Blazor application (Server prerendered), which has 2 areas:
- End user ( ordering services ) for customer
- Admin ( administration of stock, prices... ) - just for admin user
I have developed Admin part for example using bootstrap 5 (in reality I have used MudBlazor with its own bootstrap).
I needed to have "End user" part of the web site, where will be used totally different bootstrap ( https://themes.getbootstrap.com/product/space-multipurpose-responsive-template/ ).
I can split 2 web sites to 2 different "Net projects", but customer prefers to have single app, I have not found documented sample how to achieve this, so I have changed _Host.cshtml to "catch" admin pages (and point them to page Admin.cshtml
)

In .net 5 (and before) the razor engine appears to stick its nose where it doesn't belong. Luckily there is an easy fix, escape the @
