Show Roles in users grid is always empty

[korchev]

Roles are empty as they are not included by default. Here is how to display them.

1. Open SecurityService.cs and change the GetUsers method to this:

       public async Task<IEnumerable<ApplicationUser>> GetUsers()
       {
           var uri = new Uri(baseUri, $"ApplicationUsers");
   
           uri = uri.GetODataUri(expand:"Roles"); // Get the roles as well
   
           var response = await httpClient.GetAsync(uri);
   
           var result = await response.ReadAsync<ODataServiceResult<ApplicationUser>>();
   
           return result.Value;
       }
   

2. Set the Template of the Roles data grid column to this:

   <RadzenDataGridColumn TItem="YourApp.Models.ApplicationUser" Property="Roles">
      <Template>
          @string.Join(", ", context.Roles.Select(r => r.Name))
      </Template>
   </RadzenDataGridColumn>
   

The final result would look like this:
