Using Html.BeginForm inside section razor layout

I have a _Layout page with two sections: @RenderSection("LeftContent", False) and @RenderSection("MainContent", False)

All works perfectlly with another page that uses this Layout, except submit don do anything, I mean submit do not call HttpPost:

@ModelType iSAM.PROVINCIA

@Code
    ViewData("Title") = "Create"
    Layout = "~/Views/Shared/_Layout.vbhtml"
End Code

@section LeftContent
    Add navigation menu
End Section

@section MainContent
    <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
    @Using Html.BeginForm()
        @Html.ValidationSummary(True, "Error al crear el registro. Revise los errores e intente nuevamente.")

    @<fieldset>
        <legend>Fields</legend>
        <p>
            @Html.LabelFor(Function(Model) Model.DESC_PROVINCIA, "Name:")
            @Html.TextBoxFor(Function(Model) Model.DESC_PROVINCIA, New With {.style = "text-transform:uppercase"})
        </p>
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>

    @<div>
            @Html.ActionLink(" ", "ListProvincias", "_Layout", New With {.area = ""}, New With {.class = "imgBack", .title = "Back"})
    </div>

    End Using
End Section    

If I left the code outside MainContent section it works. There's a way to开发者_运维知识库 make it work inside this section?

Regards.

<input type="submit" value="Save" runat="server" />

Remove the runat="server" and it should work fine. Old web-form habits die hard = )

Edit:

While the above is an issue, it wasn't the root of the problem. The issue here was there was a @Html.BeginForm in BOTH the MasterPage and inside the content section, meaning two forms were defined and thus caused the one defined in the content section to not function.
