Question

I need to do something like this is this possible?

<%
var Controller = null;
if (Model.ID== "ABC")
    {
        Controller = "Name";
    }
    else
    {
        Controller = "Detail";
    }
%>
<% using (Html.BeginForm("edit", Controller, FormMethod.Post, new { @id="exc-" + Model.SID}))
   {%>
<%= Html.Summary(true)%>

Is this possible?

If i do I am getting exception:

ERROR: Cannot assign to an implicitly-typed local variable

Answer 1

Why not just do:

<% var Controller = (Model.ID == "ABC") ? "Name" : "Details" %> 

EDIT: Based in your update do:

<% using (Html.BeginForm("edit", 
    (Model.ID == "ABC") ? "Name" : "Details", FormMethod.Post,
    new { @id="exc-" + Model.SID})) 
   { %>

You could also use your code that you editted and just change var to string.
