Blazor Server - Edit specific data based on roles

Question

Hi there,

I have a Blazor Server app and I have a list of inventories on a razor page. When a user selects a row and edits, I would like to check if this user has an appropriate role to update the data.

Here is a sample edit page;

Let's say this user can only edit the quantity. Is there a way to do this?

Thanks in advance.

Hi @Cenk ,

Using <AuthorizeView> is also similar right?

Yes, you are right. The AuthorizeView component supports role-based or policy-based authorization.

For role-based authorization, use the Roles parameter:

<AuthorizeView Roles="admin, superuser">  
    <p>You can only see this if you're an admin or superuser.</p>  
</AuthorizeView>  

More information, see Role-based and policy-based authorization.

inject the user and role mangers then:

        @if (context.User.IsInRole("some role"))  
        {  
            <InputText id="foo" @bind-Value="model.foo" />  
        }  
        else  
        {  
            <span class="field">@model.foo</span>  
        }

Thank you @Bruce (SqlWork.com) , displaying and hiding data based on roles is a clever way :) Using <AuthorizeView> is also similar right?
