C# method in view [ aspnet mvc ]

Question

I have a view in my asp.net mvc app, this view need a condition for display (or not) some information.

Unfortunately my condition need to get an object from the session and check several conditions

For example

<body>
<sometag>
<....>
<%
var oS = HttpContext.Current.Session["key"];

if(oS.some && oS.other == "other" && oS.Propertie == varInThisPage.Propertie && etc){

if(){

   if(){

       //in any place of universe
       return true;

       }
   }
return false; // for other
}
 %>
</body>

The problem is that I have that checks this condition in various part of the view, and do not want to create a method in the model, I feel that assassinate MVC

I thinking create a method in <% %> tag, but not working

bool MyMethod(){
var oS = HttpContext.Current.Session[InfoWeb.Models.SessionObjects.ConstSession.RT_SESSION];
....
return condition;    
}

In <% Visual Studio show error expected {

When i run, show error in next line with C# code

<%: Html.ActionLink("Create New", "BG", "CVSD")%> <!-- this work before i create method -->

I use asp.net-mvc 2

Controller send only the POCO class to the view, this problem is only for view, in my case. When there is a way to invoke the method from the controller, please let me know, i am java ee dev very unlucky — user2547522

Put the logic in the controller and make the result a property of the model. — SLaks

This way you are violating technically as well architecturally the principles of MVC. Try using a ViewModel. — Vikas Raturi

<% %> blocks can only contain statements.
(the code in the block is placed inside the generated function)

To add fields or methods to the generated class, use <script runat="server">...</script>.

@ataravati: I know (see my comment on the question). This answer is not wrong. You may be confusing MVC with Razor)

ataravati Over a year ago

What I meant by wrong is that it's not a good solution. The code should be inside a Controller, as you rightly said in your comment.

Jeff Over a year ago

i agree with ataravatti, it should be on the controller, and call this via ajax or jquery asynchronously. but in any case, for whatever reason, slaks solution will work for you.
