MVC.NET Tag For Checking Roles (equivalent Of Declarative Attribute PrincipalPermission)?
Apr 5, 2010I use declarative roles in my MVC.NET controllers and I have a custom membership & roles provider.This works fine:
[Authorize(Roles = "ADMIN")]
Also, I have a base MVC.NET CustomController class that all controllers derive from, and it has a "currentUser" property that is auto-fetched from the session on demand, so all controller code just refers to "currentUser" and doesn't worry about sessions, httpcontext, etc. I've implemented the membership provider properly, as it works with other parts of the framework that just deals with providers, but until now I had not tried to access the "User" principal from a view.What is the simplest syntax for check roles in a view page? I know I can use a helper to generate a partial view but I don't want that here, I want to explicitly wrap some sections of a page in some role checks.Something like this:
<% if(currentUser.IsInRole("ADMIN") { %>
...
<% } %>
Security :: Equivalent For LoginView Based On Roles?
Apr 21, 2010I have a website where users can login and they have different roles/privileges. I want to have it where the user's view of the webpage is determined by their role. Right now I am storing the role in the UserData property of the FormsAuthenticationTicket class (which is retrieved from a database during login). When the main page is loading, I want it to check the user's role and then only show the controls/portions of the page that are for that role. For example, if the user is not an administrator, they shouldn't be able to click on a button to delete a record. At the moment I am using labels to hide or show areas depending on the user's role. Something like this:
[Code]....
[Code]....
And here is a portion of the markup code with the Labels:
[Code]....
This works, but doesn't seem to be a very good way to handle this type of thing. Is there a cleaner, more elegant way of doing this? Something similar to the LoginView control, but which I can use for roles?

Populate Treeview Based On XML Attribute Ids?
May 25, 2010I'm currently working on a Web Site application project that requires a treeview to be heirarchically structured based on the attribute ids of each node rather than the format of the XML.

At present the above is lining up all names under each other, I would like the hierarchy to be based on the attribute parentid and Id. For example: Jane Smith should be a child of Joe smith and Bob Turner is a Child of Jane Smith.
How To Hide Specific Elements On A Razor View Based On Security Without Logic In View
Apr 4, 2011I have looked all over for elegant solutions to this not so age-old question. How can I lock down form elements within an ASP.Net MVC View, without adding if...then logic all over the place? Ideally the BaseController, either from OnAuthorization, or OnResultExecultion, would check the rendering form elements and hide/not render them based on role and scope. Another approach I have considered is writing some sort of custom attributes, so as to stay consistent with how how we lock down ActionResults with [Authorize]. Is this even possible without passing a list of hidden objects to the view and putting if's all over? Other background info: We will have a database that will tell us at execution time (based on user role/scope) what elements will be hidden. We are using MVC3 with Razor Viewengine. We're utilizing a BaseController where any of the Controller methods can be overridden.

View 1 RepliesMVC :: Partial View Based On Current View's Data?
Nov 10, 2010I have a view that displays all the records of my Roles table. I want to be able to click a Role record and have a list of users that pertain to that role displayed to the right of the Roles list. I'm sure I need to use a view model for this so I can get two sets of models in one view, but I'm not sure how to set up the view model.
Controller code:

I can just as easily get the full user list with return db.Users;
So what method needs added to my repository and how should my view model look?

MVC Generic Base View Class / Error Parsing Attribute 'something': Type 'System.Web.Mvc.ViewPage'
Feb 5, 2010I can have a base class for views in an MVC project like this:
public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}
And then in the ASPX I can do this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>
This works fine; the problem is when I try to do the same with the generic version:
public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}
When I try to use this from the ASPX, like this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>
I get the error message:
Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.

Are Events Based On View State In C#
Nov 8, 2010I've read somewhere that events of ASP .NET are based on View State of ASPX page. The values of submitted controls are matched with their value of view state and if any difference is found then the corresponding event is called up.
"When events are really based on view state than why events are fired even when the view state is disabled using EnableViewState=false."
A XAML Based View Engine For MVC?
Apr 17, 2010As ASP.NET MVC has a pluggable view engine architecture, and XAML is an object descriptive mark-up that, given the right processor/ parser, can generate an appropriate UI...are there plans/ efforts to create a view engine that can turn XAML into HTML?
Personally, I think this would help to re-enforce the efforts the WPF/ Silverlight people have gone to in providing a means of seperating the view from the model/ business logic between designers and developers (via Visual Studio and Expression Blend)...
Seems like a logical step to me, but not knowing XAML as well as I should, I'm wondering if feasable, or even relevant.

MVC :: Loading Partial View Based On Html Radiobutton Selection?
Jan 15, 2010I have two strongly Typed partial views (Developers list and Testers list) and the respective views are Developers.ascx and Testers.ascx Now I want to load one partial view based on the radiobutton selected.
How to read the value of the radiobutton option? if anyone can provide Code snippet or some guidelines.
Here is my parent Controller Code & View:
Parent Controller:
[HttpGet]
public ActionResult View IT People List(string type)
{
var developers = from d in itEntity.Developers select s; return View(developers);
}
Parent View:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Mvc.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<DataModel.Developers>>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="cphHead" runat="server">
</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="cphContent" runat="server">
<h2>View All IT Dept List</h2>
<table>
<tr>
<td><label for="txType">Select List:</label> </td>
<td>
<%= Html.RadioButton("Type", 1, true)%> Developers <%= Html.RadioButton("Type", 2, false)%> Testers
</td>
</tr>
<tr>
<td colspan = 2>
<%Html.RenderPartial("Developers", Model);%>
</td>
</tr>
</table>
</asp:Content>
Two strongly Typed Controllers are:
[HttpGet]
public ActionResult Developers()
{
var developers = from d in itEntity.Developers select d; return View(developers);
}
[HttpGet]
public ActionResult Testers()
{
var testers = from t in itEntity.Testers select t; return View(testers);
}
Forms Data Controls :: Tree View Image/Icon Based Off A Value?
Mar 18, 2010I have a tree view which uses my SQL database and tables to generate the tree view and list of reports under the different categories and folders. That all works perfectly... However, since some of the reports are private, and some of the reportsare pubic I was hoping to be able to adjust the image of the report to a different icon to differentiate between the two. Here is my code which generates the tree view and lists the reports below it:(All code is in VB.NET)
[Code]....
I've thought about this but havn't tried to many options, figured I would see if anything stood out as easy as node.setimageurl = "~/images/image.png" etc.
