[Solved] showing grid data role based

[Gerard Eikelboom]

Hi,
we are now implmenting sequirity in our application and one of the things is that I want to show data only when the user has a specific role.
We make use of the std asp.net role provider.
I have alreay implemented such for commands Edit /Delete in my grid. That works good.

columns.Command(commands =>
              {
             if (User.IsInRole("Administrator")) commands.Edit().ButtonType(GridButtonType.Image);
            if (User.IsInRole("Administrator")) commands.Delete().ButtonType(GridButtonType.Image);

I hope it's possible.

Hello Gerard Eikelboom,

 I am not sure what you mean by "show data only when the user has a specific role". Could you please clarify?

Atanas,
What I mean is when my Grid is initialised I get the data:

.DataBinding(dataBinding => dataBinding.Ajax().Select("_GetUsers", "User"))

What I normal do in my controller class when I want users to have permission based on a role to see it:

[Authorize(Roles="Administrator")]
       [GridAction]
       public ActionResult _GetUsers()

So only administrators have permission to go into that action.
I cannot do that with a GridAction because I get the error The requested Url did not return JSON.
Althought it's not showing data, so that's ok.

So, I wonder if you can handle it in the Grid itself, like you can with the command buttons (first piece of code)

Regards,
Gerard

Hi Gerard Eikelboom,

 No, the grid cannot handle this. What you can do is show the grid only when the user has rights:

<% if (User.IsInRole("Administrator")) { %>

<%= Html.Telerik().Grid() %>

<% } %>

Atanas,

Yes that's an option.
What I do now is handle it in my controller using my own written role provider implementation.
It's shows the grid but it returns an empty collection.
I will think about your option.

thanks,
