Setting Visible Disabled with Security Roles

Radzen Studio Blazor Server
1

Hi Radzen,
I'm struggling on setting the component "visible"" and "disabled" properties using the Security.IsInRole object.
What is the proper way to do this in the Designer.
I have used the forum to search and have tried the suggestions, it sometimes works for one component and not for an other.
Getting : too many characters (cs1012) and all sorts of errors.

In Navigation items this with one or two options works: but not with 3 options

@Security.IsInRole(new string[]{"XXX","YYYY","ZZZZ"})

also tried this

@Security.IsInRole(new string[]{'XXX','YYYY','ZZZZ'})

Please advice :
PS: using page properties is not a clean solutions with many roles defined.
Regards,
Mehmet

Just tested this and got no errors. Tested with 3 options and more. What is the generated code? What is the exact compilation error?

This won't work because strings in C# need ". Single quotes are for char which are only one character long.

Please test with the Navigation items (menu) :

reproduce:
Create a menu (with no path , to make a sub menu heading)
Create a menu item under the first one .
And put the Security.IsInRole with three Rols in it and you will get an error , with two roles it wil not complain.
Rolenames must be of some length , "ADMIN","Tenantsadmin","Helpdesk" e.g.

The singe quotes I have used with the ${} notation without the @ sign, just to be sure ..

The error is not given right away, I have stopt and run the application again ..

dotnet: D:\Radzen\Blazor\xx\xxx\RadzenAPP\server\Shared\MainLayout.razor(137,75): error RZ9986: Component attributes do not support complex content (mixed C# and markup). Attribute: 'Visible', text: 'Security.IsInRole(new string[]{"MCM","tenantsadmin","Helpdesk"}) ' [D:\Radzen\Blazor\xx\xxx\RadzenAPP\server\RadzenAPP.csproj]

PS: I notice that there is a " " blank- space char at the end of the line with code like:
'Security.IsInRole(new string[]{"MCM","tenantsadmin","Helpdesk"}) '

That's what I tested with ...

<RadzenPanelMenuItem Text="Item 0" Visible="@Security.IsInRole(new string[] { "One", "Two", "Three", "Four", "Five"})">
</RadzenPanelMenuItem>

In addition the IsInRole method is declared as params

public bool IsInRole(params string[] roles)

This means you can use it like this:

Security.IsInRole("One", "Two", "Three", "Four", "Five")

Trailing whitespace after the ) may indeed be a problem - delete it if there is any.
