Can I Remove the WebForms Script Tags from My ASP .NET MVC View?

Question

<div class="firstColumn">
<% for (int rowCount = 0; rowCount < Model.TaskAttributes.Count; rowCount += 2)
   {%>
       <%= Html.EditorFor(model => model.TaskAttributes[rowCount]) %>
 <%}
%>
</div>

So, I have this bit of code which works fine, but I'm unhappy with all the MVC mark-up.

The solution does not support Razor syntax yet, so I'm stuck with this syntax, but I'm wondering if it can be cleaned up at all.

What I was thinking should work is this:

<div class="firstColumn">
<% for (int rowCount = 0; rowCount < Model.TaskAttributes.Count; rowCount += 2)
   {
       Html.EditorFor(model => model.TaskAttributes[rowCount]);
   }
%>
</div>

This does not render any EditorFor's to my page, though. It appears that the '<%=' before the editorFor is cruicial. Is there any way to express this without having to close and open tags?

even if that code works, it s not a good code. it shouldnt have been doing that in your view. — DarthVader

I am aware of this. I have inherited technical debt and do not have the time scheduled to rewrite and propagate the changes everywhere, but if a small clean-up is possible then I would take that. — Sean Anderson

You could try @Html.EditorFor(model => model.TaskAttributes[rowCount]);. — kerzek

@SeanAnderson You need to be very, very careful when using Response.Write. This is a raw dump of information into the response stream. You lose all validation and safety of the output and take total responsibility for it. I don't know that's worth losing a couple WebForms tags... — Yuck

That's really about as good as it's going to get. You need to have:

<%= Html.EditorFor(model => model.TaskAttributes[rowCount]) %>

...so that the output is emitted to the response stream. Even with MVC3 syntax you would have to write:

@for (int rowCount = 0; rowCount < Model.TaskAttributes.Count; rowCount += 2) {
    @Html.EditorFor(model => model.TaskAttributes[rowCount])
}

and not just:

@for (int rowCount = 0; rowCount < Model.TaskAttributes.Count; rowCount += 2) {
    Html.EditorFor(model => model.TaskAttributes[rowCount])
}

<%= is shortcut for Response.Write() . Have you tried that?

This is a valid MVC3 conversion, but the OP has mentioned that Razor syntax is not available to him. He's just trying to refactor some of the seemingly extraneous script tags.
